Description

A kind of operational approach and autonomous networks of autonomous networks

Technical field

The present invention relates to the technical fields of communication, and the service communication method and one kind more particularly to a kind of autonomous networks are certainly Control network.

Background technique

Network (including internet) makes that information and other information resource can be exchanged between different individual and mechanism.Net Network generally includes the technologies such as access, transmission, signaling and network management.These technologies are widely seen in all kinds of documents.

Connect the terminals to the path technology (local loop of such as terminal installation and network edge) of a wide-area transmission network From the modem of 14.4,28.8 and 56K develop to including ISDN, T1, cable modem, DSL, Ethernet and Technology including wireless connection.

Now with transmission technology in the wide area network include: synchronous optical network (SONET), dense wave division multipurpose (DWDM), Frame relay, asynchronous transfer mode (ATM) and resilient packet ring (RPR).

(agreement and side such as the communication that is used to establish, maintain and terminate in a network in all different signaling technologies Method), with being most widely used for Internet protocol (IP).In fact, almost all of communication and digerait think collection sound Sound (such as phone), video and data network will be inevitable in a network (such as internet) based on IP agreement of one. Just as illustrating an author: " something is clear, that is, the integration disparate networks based on IP are in one The train of body has sailed out of station, some passengers are to this great enthusiasm of travelling, and other are then very reluctantly dragged And go, and cry, cry, savate enumerate many disadvantages of IP.But whether which kind of defect it has, IP has been adopted as a kind of row Industry standard has the space of so big potentiality and development other than it without any other technology."

With the business explosive growth of Internet, application range has expanded to social every field and each row Industry.From the point of view of telecommunications industry, traditional telecommunication service is transmitted using IP more and more, i.e., so-called Everything Over IP.The frame of existing telecommunications network will gradually be turned to from circuit switching and its networking technology using packet switch especially IP as base The new frame of plinth, the net loaded business of telecommunications will turn to based on data service from based on phone.

TCP/IP network protocol

TCP/IP (Transmission Control Protocol/Internet Protocol, transmission control protocol/ Inter-network agreement) it is the agreement being most widely used in the world at present, its prevalence and the close phase of fast development of Internet Pass-TCP/IP is initially designed by the prototype Advanced Research Projects Agency Network for internet, it is therefore an objective to provide that a whole set of is convenient and practical, can apply In the agreement in multiple network.Facts proved that TCP/IP has accomplished this point, it becomes easy the network interconnection, and makes The fact that more and more networks are added thereto, become Internet standard.

* application layer-application layer be all users towards application program general designation.TCP/IP protocol suite is in this layer There are many agreements in face to support different applications, and the realization of everybody many known applications based on Internet is not just from Open these agreements.Http protocol, file transmission File Transfer Protocol, Email have been used as we carry out WWW (WWW) access It sends and uses SMTP, the parsing DNS Protocol of domain name, Telnet Telnet agreement etc., be all to belong to TCP/IP application layer 's.For user, user it is seen that be mostly patterned operation interface as constructed by software one by one, and it is practical Running background is above-mentioned all kinds of agreements.

* transport layer-transport layer function is mainly to provide the communication between application program, and TCP/IP protocol suite is in this layer Agreement have TCP and UDP.

* network layer-network layer is very crucial in TCP/IP protocol suite one layer, main definitions IP address format, from And the data of different application type is enabled to transmit on internet unobstructedly, IP agreement is exactly a network layer protocol.

* network interface layer-network interface layer is the bottom of TCP/IP software, is responsible for receiving IP data packet and passes through net Network is sent, or physical frame is received from network, is extracted IP data packet out, is given IP layers.

Does is IP how to realize the network interconnection? the network system and equipment of each producer's production, such as Ethernet, packet switch Net etc., they are unable to intercommunication between each other.The main reason for being unable to intercommunication is the basic unit because of their transmitted data The format of (being technically referred to as " frame ") is different.IP agreement is actually a set of protocol software being made of software program, its handle Various differences " frame " are uniformly converted into " IP data packet " format, and this conversion is a most important feature of internet, so that All various computers can realize intercommunication on the internet, that is, have the characteristics that " opening ".

Does is so, what " data packet "? what feature does it have again? data packet is also a kind of form of packet switch, just It is the data sectional transmitted to be broken into " packet ", then send out.But it belongs to " connectionless ", is each of breaking into " packet " (grouping) is all sent out as one " independent message ", so being called " data packet ".In this way, before starting communication There is no need to first connect each circuit, each data packet is different to be established a capital through same path transmission, so being called " no to connect Direct type ".This feature is extremely important, and in the case where text information transmission, it substantially increases the robustness and safety of network Property.

Each data packet has message and the two parts of header, has the required contents such as purpose address in header, makes each Data packet can accurately arrive at destination without same path.The number for being reduced into and sending originally is reconfigured in destination According to, this will IP have the function of grouping be packaged sum aggregate be combined dress.

In practical transmit process, data packet also wants that data packet can be changed according to the packet size of passed through network provision Length, the maximum length of IP data packet is up to 65535 bytes.

How to guarantee that service quality (QoS) is a main problem of the internet IP.If we are by QoS major milestones It is chronological, although numerous research report attempts to solve this problem for a long time, it is not difficult to find out that internet QoS is The helpless history for constantly lowering the requirement, and constantly failing.From " Inte Serv " (1990) to " Diff Serv " (1997), then arrive " Lightload " (2001), it is various to seem effective QoS minor betterment scheme and add up, apart from network-wide basis quality guarantee For target still as the moon in water, QoS seems close, in fact distant unreachable.

Early in the internet IP initial stage, video signal application has become the target of network service, such as MBone.Due to lacking Weary effective quality guarantee can not carry out commercially valuable video communication service for a long time, weaken the profit of the internet IP Ability.Therefore, network transmission quality problem is solved, there is very big commercial value.Network transmission quality is embodied in packet loss And error code, computer document are insensitive for the mistake in transmission, even if most data packets are all lost in transmission process, as long as There is the retransmission mechanism of TCP, computer still will be considered that network is available.But if packet loss or the bit error rate are higher than one thousandth, The view sound quality decline of synchronous video signal will be will cause.Empirical data teaches that the video communication of high-quality even requires packet loss Rate and the bit error rate are lower than ten a ten thousandths.The test data of current network environment shows that most packet losses occur in router Inside, and the error code generated in optical fiber transmission then almost can be ignored.

* why be " Inte Serv " unsuccessful?

" Inte Serv " is established on the basis of individual flow resource reservation, using Resource Reservation Protocol (RSVP) agreement.In a large-scale network environment, if a part can be reserved between two video terminals Bandwidth resources, it is dedicated for the videoconferencing service, it sounds wonderful, but actual uplink is obstructed.

Firstly, this scheme requires whole network equipment transformation, it is equal to networking again, practical operation is almost impossible.

Even if the videoconferencing service for being 2Mbps is protected secondly, realizing the whole network transformation, such as can be in each interchanger 2Mbps bandwidth is stayed, quality guarantee can be solved? answer is equally negative.

The 2Mbps bandwidth of so-called RSVP can only for macroscopic view for, if 1 second data concentrate on the first half second transmission, It will result in problem, form periodic burst flow.Since the core concept of the internet IP is to do one's best, in each net Network node, interchanger always attempt to forward data with prestissimo, necessarily cause after a video signal stream passes through multistage switches Flow distribution is uneven, and multiple non-uniform asynchronous streams are combined, and will generate whithin a period of time bigger uneven.? That is network flow centainly has periodic obstruction.With the increase of video signal number of users, periodically there is no upper for obstruction Limit will directly result in packet loss when being more than interchanger internal reservoir amount.

* why be " Diff Serv " unsuccessful?

After " Inte Serv " comes out 7 years, a kind of new method " Diff Serv " is come into vogue." Diff Serv " attempts There is provided a kind of better than the network service done one's best, this method does not need complicated the whole network resource reservation, implement it is very simple, only " priority " label is stamped in each data packet, network switch first processing has the video signal data of " priority ".Its It is that VIP client provides gold card that basic principle, which cans be compared to bank, can effectively reduce the queuing time of high-end customer.This method has been listened Come also fine but actually still unworkable.

We cannot ignore a simple fact, and single videoconferencing service flow is far longer than the non-videoconferencing service of tradition (hundred times or more).

As long as there is a small amount of video signal user, what is seen on network is nearly all video signal data packet.If most data packets are all Hold gold card, be also just far from being VIP.It is not enforceable additionally, due to the internet IP, although QoS is that user has formulated one IImmune moral standards are covered, but it is at all unrealistic to require others all consciously to execute.

Therefore, " Diff Serv " is other than the use in a small number of Enterprise Special Networks, it is difficult to effectively push away in extensive public network Extensively.

* why be " Light load " unsuccessful?

Since the internet IP is gradually popularized, people find incessantly solves the good recipe that network quality guarantees.Network Technical specialists rack one's brains by more than ten years, and two big QoS schemes are undesirable.In the overall situation lost the confidence to solution QoS Under, some to be reluctant that the people to leave behind a good reputation proposes be not the method for method, i.e., " Light load ".It is so-called underloading that it imagines substantially Network, it is believed that as long as wide to foot straps, fiber entering household is just not concerned about network congestion.

Can the imagination for being lightly loaded network be all right? answer still negates.

Current network technology brainstrust does not appear to recognize that a basic principle is exactly the root of Network Packet Loss phenomenon Caused by being the even property of mass flow discrepancy.It is slightly quicker from macroscopically, being sent in a period, necessarily lead to another period Crowded, as long as network flow is uneven, the peak flow that network is likely to be breached can take appoint in a short time without the upper limit It anticipates big bandwidth.

In fact, as long as there is 2Mbps bandwidth to transmit pretty good video. programs, if there is 8Mbps bandwidth, so that it may Transmit the video content of HDTV quality.However, if our optional points on general Websites see passage or a photos, it is existing Modern Website server majority uses gigabit network interface, and moment flow is the decades of times of HDTV.If there are many a similar website, It by chance piles up, can be more than that needed for the whole network user uses HDTV, can take in the burst flow that some short time generates Any wide network.Statistical analysis display, this collision are very frequent.

The internet IP attempts to absorb moment flow using reservoir, and consequence is to increase propagation delay time.Due to storage Ability is limited, and burst flow does not have the upper limit.Therefore, the probability that this equipment packet loss can only be improved using storage method, in this section The burst flow that point absorbs will cause bigger pressure to next node.Video signal flow continually, interchanger storing mode It exacerbates burst flow to converge to weak node, Network Packet Loss is inevitable.

Current network construction persons add " Diff Serv " technology using underloading, can deal with the VoIP voice of narrowband Business.This is because voice does not account for major part in network total flow, once generation is crowded, computer document can be sacrificed, it is right Voice is preferential.But for the video communication of high bandwidth, local dilatation can only receive the effect temporarily improved.If its His local also dilatation, and then when the river rises the boat goes up for the inhomogeneities of network flow, led to the effect decline of original dilatation part.If The whole network is all averaged if dilatation, and transmission quality is restored to original without the appearance before dilatation again.That is, whole dilatation is Invalid.

Current device manufacturer recommends each household tens of or even up to a hundred million ultra wide band accesses net, even if there is light in every family Fibre arrives family, is still difficult to show the video communication service of quality guarantee to consumer.Complicated QoS means at most can only again The transmission quality of the internet " improvement " IP, and " can not guarantee " network transmission quality.

Specific embodiment

In order to make the above objects, features, and advantages of the present application more apparent, with reference to the accompanying drawing and it is specific real Applying mode, the present application will be further described in detail.

The concept of entropy was proposed in 1865, was initially one of the state of matter parameter for describing " Energy Degeneration ", It is widely used in thermodynamics.But entropy is only the physical quantity that can be measured by heat change at that time, essence It is explained still without good, until a series of scientific theory development such as Statistical Physics, information theory, the essence of entropy is just gradually explained It is clear, that is, the essence of entropy is a system " inherent confusion degree ".

Negentropy is exactly the opposition of entropy, and what entropy represented is unordered, and what negentropy indicated is then ordered into.Draw negentropy, Ke Yijian Single is interpreted as after absorbing substance or energy from the external world, reduces the entropy of system, becomes more orderly.

When the mankind put fire, timber, air, clay, stone when burning out pottery, smelt metal out together, one The similar photosynthetic variation of kind occurs --- negentropy.

After the mankind continuously can extract negentropy from the Nature with combined form, it is upper just to declare that the mankind have stood The top of biological chain.It is separately to build a set of negentropy except the charcoal circulation driven and follow with sunlight that the essence of intelligence, which is in nature, Ring system.

Network world be also in this way, existing internet be substantially follow this code of conduct of doing one's best without pipe Reason, mixed and disorderly unordered network are exactly in other words the extra high network of entropy, and existing Internet company is special in entropy Factum criterion is established on high internet, is allowed to orderly, negentropy height.

For example, e-commerce website is clearly presented the commodity of various businessmans with certain rules in front of the user, miscellaneous Disorderly unordered thing is shown in an orderly manner, and here it is the commercial values of e-commerce website！

Does is innately it exactly that negentropy is extra high, very well ordered either with or without a kind of network? here it is the autonomies that inventor proposes The concept of network, it is congenital manage it is very well ordered.

Traditional viewpoint is to be from individual to society in a multilayer system, the flat world of managing state affairs of cultivating oneself and putting family in order, layer by layer outward Extension.A people and society, for people, this is not one or the other alternative.

Body is seen with body, this is to say human nature；House is seen with family, has begun with small-scale public character；With Guo Guan state, to see all over the world All over the world, the public character of personal behavior has been put into maximum.

So-called " the own boundary of group ", is exactly the boundary between this multilayer, what layer to do the thing of what layer at, not cross the border and It is out of normal activity.

Same reason is suitble to network world, and autonomous networks that are distributed, having levels have agreed traditional wisdom without prior consultation！

The autonomous networks proposed below to the embodiment of the present application are introduced:

One, the topological structure of autonomous networks

Referring to Fig. 1, a kind of structural schematic diagram of autonomous networks of the application one embodiment is shown.

As shown in Figure 1, autonomous networks, are a kind of distributed centrally controlled networks, it include multiple press in autonomous networks The autonomous cloud of layer distribution, i.e. the overall network structure of autonomous networks are interconnected together by multiple minor structures for being known as autonomous cloud, Autonomous cloud shows hierarchical structure when interconnecting.

Since the autonomous cloud of top layer, each autonomy cloud can be interconnected with one or more next layer of autonomous clouds, The autonomous cloud of lower layer is connected with more next layer of autonomous cloud again, and until bottom autonomy cloud, all autonomous clouds are with this Mode is formed autonomous networks net after connecting layer by layer.

Obviously, this hierarchical structure is tree, each autonomous cloud is exactly a node in tree, entire autonomy net Network is exactly the tree being made of multiple autonomous clouds as node.

As shown in Figure 1, the autonomous networks include four layers, the autonomous cloud in the 4th layer (L4) connects multiple third layer (L3) In autonomous cloud, the autonomous cloud in multiple second layers (L2) is connected in the autonomous cloud in third layer (L3), in the second layer (L2) Autonomous cloud connect the autonomous cloud in one or more first layers (L1).

Fig. 2 is participated in, a kind of structural schematic diagram of autonomous cloud of the application one embodiment is shown.

As shown in Fig. 2, autonomous cloud is the basic minor structure in autonomous networks structure, and transport autonomous networks normally Capable structural units.

One autonomous cloud, can be in the function of autonomous cloud internal independence realization autonomous networks in the case where configuring correct situation.

When autonomous cloud can not be connected due to communication failure with upper and lower level autonomy cloud, business in autonomous networks still can be with It is realized inside single autonomous cloud, this is also the origin (autonomy operation) of autonomous cloud title.

When autonomous cloud can be with the autonomous cloud normal communication of upper and lower level, it is bigger that these autonomous clouds just constitute a range Autonomous networks, the business across autonomous cloud may be implemented.

In the concrete realization, each autonomous cloud includes main control server, thin cloud server, terminal and exchange network.

1, main control server

Main control server is the centralized control node of autonomous cloud, the function of realization mainly include to the equipment in autonomous cloud into Row management realizes that autonomous cloud inside and the management across business, autonomous networks between autonomous cloud are communicated to realize higher Management etc., by main control server, each autonomy cloud can become an independently operated centrally controlled network.

In each autonomous cloud, main control server and thin cloud server access exchange network, i.e. main control server can be with Multiple thin cloud servers are attached by the same exchange network, this exchange network and with it connect common group of equipment At the master control thin cloud of autonomous cloud, the quantity of the master control thin cloud in autonomous cloud is one, and the equipment in master control thin cloud can be with tree The various topological classifications such as type, star-like, total exchange are attached.

In general, the equipment in autonomous networks is registered firstly the need of on main control server, then accessed by networking process Autonomous networks, the equipment that do not register can not network, and cannot obtain the service of autonomous networks offer.

Referring to Fig. 3, a kind of structural schematic diagram of main control server of the application one embodiment is shown.

As shown in figure 3, main control server 300 mainly includes network transceiving module 301, device management module 302, multicast pipe Manage the modules such as module 303, Service Processing Module 304.

Wherein:

Network transceiving module 301 is responsible for sending and receiving for data packet, and when received data packet can check whether data packet accords with It closes the packet format of autonomous networks, whether be destined to the packet of main control server, according to disappearing in data packet if meeting the requirements Type is ceased by packet delivery to device management module 302, multicast management module 303 and Service Processing Module 304.

Device management module 302 be responsible for processing and autonomy cloud in equipment enter net state it is related and with neighboring autonomous cloud it Between the relevant agreement of access state, safeguard relevant with these states table, realize networking such as equipment and logout, it is adjacent oneself Control the processes such as access and the disconnection between cloud.

Multicast management module 303 is responsible for multicast traffic stream or and the multicast number across autonomous cloud inside processing and autonomous cloud According to relevant agreement is flowed, table relevant with these data flows is safeguarded, realize creation and destruction, data such as data flow transmitting terminal Flow the processes such as addition and deletion, the management across autonomous cloud data flow of receiving end.

Service Processing Module 304 is responsible for processing agreement relevant with various autonomous networks business, maintenance and these business phases The table of pass realizes the process of such as live broadcast, videophone, video conference service.

2, thin cloud server

Thin cloud server is the exchcange core of autonomous cloud, in most cases, the communication that the equipment in autonomous networks issues Data arrive at final destination by the forwarding of thin cloud server.

Furthermore, thin cloud server includes border router, terminal sub-control server and boundary sub-control server.

2.1, sub-control server

Terminal sub-control server and boundary sub-control server are also referred to as sub-control server, and sub-control server is the number of autonomous cloud According to forward node, there is a upstream Interface and a downstream interface.Upstream Interface is used to be connected to the master control thin cloud of autonomous cloud, Downstream interface can be attached with the border router in terminal or other autonomous clouds by the same exchange network, this Exchange network and the equipment connected with it have collectively constituted a sub-control thin cloud of autonomous cloud.

Wherein, terminal sub-control server and terminal access another exchange network, and corresponding sub-control thin cloud is also known as terminal point Control thin cloud.

Boundary sub-control server and border router access another exchange network, and corresponding sub-control thin cloud is also known as boundary point Control thin cloud.

In the embodiment of the present application, master control thin cloud, sub-control thin cloud may be collectively referred to as thin cloud.

Assuming that the hierarchical structure of autonomous cloud is 4 layers, and the thin cloud level inside each autonomous cloud is 2 layers, then entire autonomous The hierarchical structure of thin cloud is 8 layers in network.

Equipment in sub-control thin cloud can be equally attached with the various topological classifications such as tree-shaped, star-like, total exchange.

Each of master control thin cloud sub-control server can correspond to a sub-control thin cloud, and sub-control thin cloud and master control are micro- Cloud realizes connection by being multiplexed the same sub-control server.

Since thin cloud server can be linked into simultaneously in two different thin clouds, so can pass through between multiple thin clouds Thin cloud server, which is realized, to be interconnected, and when connection needs to meet following rule:

It cannot be interconnected between sub-control thin cloud inside autonomous cloud；

When master control thin cloud inside autonomous cloud is connected with sub-control thin cloud, the upstream Interface access master control of thin cloud server is micro- Cloud, downstream interface access sub-control thin cloud；

Master control thin cloud can be connected with the sub-control thin cloud in upper layer autonomy cloud, and the upstream Interface of thin cloud server accesses sub-control Thin cloud, downstream interface access master control thin cloud；

Master control thin cloud can only be connected with the sub-control thin cloud in a upper layer autonomy cloud；

Sub-control thin cloud can be connected with the master control thin cloud in lower layer's autonomy cloud, and the upstream Interface of thin cloud server accesses sub-control Thin cloud, downstream interface access master control thin cloud；

Sub-control thin cloud can be connected with the master control thin cloud in multiple lower layer's autonomy clouds.

CRC can be made of 4 bytes, and calculation method follows the Ethernet CRC algorithm of standard.

2, autonomous networks address

There are 3 kinds of different addresses in autonomous networks, is link address, unicast address, multicast address respectively.

Wherein:

Link address uses in the networking process of equipment, and the numerical value of its 8 bytes is identical, such as 0x0101 0x0101 0x0101 0x0101.Link address is for distinguishing the equipment being linked into the same thin cloud；

Unicast address is the global logic address of network interface, such as 0x0102 0x0304 0x05060x0708；

Multicast address is used to distinguish the multicast traffic stream in the same autonomous cloud, and multicast address can only autonomous net as a purpose Network address uses and cannot control network address as being originated from and use.

Rear 4 bytes in 8 bytes can be used in multicast address, and preceding 4 bytes are fixed as full 0, such as 0x0000 0x0000 0x0012 0x3456。

3, type of data packet

There is the data packet of 3 seed types in autonomous networks: connection packet, unicast packet, multicast packets.

Wherein:

Connection packet uses in the networking process of equipment, its purpose autonomous networks address and from network address is controlled all is Link address respectively indicates the recipient and sender of connection packet；

Unicast packet uses after equipment networking, the agreement PDU being used for transmission between equipment, its purpose autonomous networks address Be originated from that control network address be all unicast address, respectively indicate the recipient and sender of unicast packet；

Multicast packets use after equipment networking, the data PDU being used for transmission between equipment, its purpose autonomous networks address It is multicast address, is unicast address from network address is controlled, respectively indicates the recipient and sender of multicast packets.

In order to distinguish different data packets, can be arranged as follows in advance:

The value of ethernet type is 0x0800；

The Packet type value of connection packet is 0x10；

The Packet type value of unicast packet is 0x02；

The Packet type value of multicast packets is 0x81.

When later to being specifically partially described in data packet, it will usually omit for ethernet type and VLAN The description on head.

4, data packet is transmitted

4.1, connection packet

Connection packet is not supported to forward, and can only transmit between two equipment in the same thin cloud.

Connection packet indicates the sender and recipient of data packet using link address.8 byte values of link address are all Identical, numerical value is usually exactly the logic port address of the network interface of sender or recipient.

4.1.1, non-forwarding nodes behavior

For main control server and terminal, with needing to be arranged the MAC that target MAC (Media Access Control) address is recipient when sending connection packet Location, setting source MAC are the MAC Address of oneself, and setting purpose autonomous networks address is the link address of other side, and setting is originated from Control the link address that network address is oneself.Need to check whether target MAC (Media Access Control) address is oneself MAC when receiving connection packet Location.

4.1.2, forward node behavior

For sub-control server and border router, they maintain two Ethernets in inside and send matching list.Two Table corresponds to two network interfaces, and downstream interface is No. 0 mouth, and corresponding matching list is No. 0 table, and upstream Interface is No. 1 mouth, corresponding Matching list be No. 1 table.It include 256 list items, the logic port address corresponding to 8bit in every matching list.In each list item Including an ethernet mac address (physical port information) and a transmission flag bit.Flag bit is that 0 expression port is invalid, MAC Address is meaningless.Flag bit is that 1 expression port is effective, and MAC Address is exactly the mesh used when sending data packet to the port MAC Address.

Setting is originated from the link address for controlling that network address is oneself when forward node sends connection packet, and source MAC is arranged For the MAC Address of transmission interface, the link address that purpose autonomous networks address is other side is set.It is arranged first when target MAC (Media Access Control) address The corresponding table item in Ethernet transmission matching list is first searched according to the link address of other side.For example the link address of other side is 0x3434 0x3434 0x3434 0x3434, connection packet need to be dealt into No. 1 mouth, then inquire No. 1 Ethernet and send in matching list 0x34 list item.The connection packet is not sent if sending flag bit and being 0, if sending flag bit and being 1 purpose MAC is set Location is then the MAC Address in list item is sent.

Forward node receive connection packet when need to check target MAC (Media Access Control) address whether be receiving interface MAC Address.

4.2, unicast packet

Unicast packet indicates the sender and recipient of data packet using unicast address.Unicast packet can pass through data forwarding section The forwarding of point, is transferred to another thin cloud from a thin cloud, realizes the communication of equipment within the scope of full autonomous networks.

4.2.1, non-forwarding nodes behavior

Setting is needed to patrol from the overall situation that network address is oneself is controlled for main control server and terminal, when sending unicast packet Address is collected, setting source MAC is the MAC Address of oneself, the global logic that purpose autonomous networks address is recipient is arranged Location, setting target MAC (Media Access Control) address are MAC Address corresponding to next recipient of unicast packet.

For terminal, next recipient of unicast packet is exactly No. 0 mouth of the sub-control server of affiliated thin cloud.

For main control server, next recipient of unicast packet needs to calculate according to the following rules:

When autonomous cloud layer time is 1, compare recipient global logic address and first 6 of the global logic address of oneself Whether byte is identical, if identical, the local logical address that next recipient is arranged is the global logic address of recipient 7th, 8 bytes, if it is different, next recipient of unicast packet is exactly No. 0 mouth of border router in master control thin cloud；

When autonomous cloud layer time is 2, compare recipient global logic address and first 4 of the global logic address of oneself Whether byte is identical, if identical, the local logical address that next recipient is arranged is the global logic address of recipient 5th, 6 bytes, if it is different, next recipient of unicast packet is exactly No. 0 mouth of border router in master control thin cloud；

When autonomous cloud layer time is 3, compare recipient global logic address and first 2 of the global logic address of oneself Whether byte is identical, if identical, the local logical address that next recipient is arranged is the global logic address of recipient 3rd, 4 bytes, if it is different, next recipient of unicast packet is exactly No. 0 mouth of border router in master control thin cloud；

When autonomous cloud layer time is 4, the local logical address that next recipient is arranged is the global logic of recipient Location the 1st, 2 bytes；

Corresponding equipment is found according to the local logical address of next recipient；

If equipment is the border router in master control thin cloud, next recipient of unicast packet is exactly side in master control thin cloud No. 0 mouth of boundary's router；

If equipment is not the border router in master control thin cloud, the topological classification of master control thin cloud is checked；

If the topological classification of master control thin cloud be it is star-like, next recipient of unicast packet is exactly the center in master control thin cloud No. 1 mouth of equipment；

If the topological classification of master control thin cloud is total exchange, check that equipment is sub-control server；

If equipment is sub-control server, next recipient of unicast packet is exactly No. 1 mouth of sub-control server；

If equipment is not sub-control server, equipment is exactly the equipment under some sub-control thin cloud, unicast packet it is next A recipient is exactly No. 1 mouth of the sub-control server of the sub-control thin cloud；

Main control server and terminal need to check whether target MAC (Media Access Control) address is oneself MAC Address, mesh when receiving unicast packet Autonomous networks address whether be oneself global logic address.

4.2.2, forward node behavior

For sub-control server and border router, they will appreciate that the global logic address of No. 0 mouth and No. 1 mouth after networking And level of the corresponding thin cloud of No. 0 mouth in autonomous networks.

Provide that the protocol process module inside head-end site is made using the global logic address of No. 0 mouth in autonomous networks It is communicated for the unicast address and other equipment of oneself.

Forward node is when receiving the unicast packet on No. 0 mouth or No. 1 mouth, it is necessary first to check target MAC (Media Access Control) address Whether be receiving interface MAC Address, then according to purpose autonomous networks address, oneself No. 0 mouth global logic address and Next recipient of thin cloud level calculating unicast packet.

Assuming that purpose autonomous networks address is D8.D7.D6.D5.D4.D3.D2.D1, No. 0 mouth global logic address of oneself For S8.S7.S6.S5.S4.S3.S2.S1.Wherein D8 to D1, S8 to S1 respectively indicate 1 byte in address.

Before calculating, purpose autonomous networks address and No. 0 mouth global logic address are divided into 3 according to No. 0 mouth thin cloud level Point, it is referred to as address 2, address 1 and address 0.

Following table is the method for dividing address:

Calculate 4 kinds of situations of next recipient's time-division:

If 3 parts of two addresses are all identical, indicate that next recipient is exactly oneself, it, will at this time without forwarding Data packet is given internal protocol process module and is handled；

If two addresses only have 0 part of address different, indicate that next recipient is located in thin cloud belonging to No. 0 mouth, it is right The logic port address answered is exactly 0 part of address of purpose autonomous networks address；

If 2 part of address of two addresses is identical but 1 part of address is different, indicates that next recipient is located at No. 1 In thin cloud belonging to mouthful, corresponding logic port address is exactly 1 part of address of purpose autonomous networks address；

If 2 part of address of two addresses is not identical, next recipient is exactly thin cloud (master control thin cloud belonging to No. 1 mouth Or sub-control thin cloud) in be known as a special installation of upper layer forward node, its logic port address is when forward node networks It obtains；

If necessary to forward after the completion of calculating, then pair in the Ethernet matching list of corresponding interface is inquired according to calculated result List item is answered, does not send the unicast packet if sending flag bit and being 0, target MAC (Media Access Control) address, which is arranged, if sending flag bit and being 1 is MAC Address in list item, setting source MAC are then the MAC Address of corresponding interface is sent.

When internal protocol process module sends unicast packet, setting is with being originated from the global logic for controlling that network address is No. 0 mouth Location, setting purpose autonomous networks address are the global logic address of recipient.Then according to the global logic address of recipient, from Oneself No. 0 mouth global logic address and thin cloud level calculate next recipient of unicast packet.Calculation method and calculating come from 0 The method of next recipient of number mouth or the unicast packet on No. 1 mouth is identical, and target MAC (Media Access Control) address and source MAC is then arranged Method it is also identical.

There are the data communication scenes of point-to-multipoint in business in autonomous networks, for example, more people watch that one shows simultaneously The concert of live streaming largely the side of attending a meeting while watching video and audio of speaking party, etc. in video conference.

It, can be due to reality if still being communicated using point-to-point unicast mechanisms under these data communication scenes Network bandwidth it is limited and may cannot achieve, therefore, for these data communication scenes, autonomous networks realize cast communication Mechanism can carry out the data communication of point-to-multipoint in network-wide basis, the bandwidth without consuming magnanimity.

Feature of the cast communication mechanism in Dan Zizhi cloud includes at least one following:

Using multicast address as the unique identification for distinguishing multicast traffic stream, i.e., no matter is the data flow that the same sender issues How many recipient, in the life span of data flow, its multicast address is constant；

Multicast address Dynamic Maintenance is distributed in real time when data flow generates, is discharged in real time in data flow extinction time；

Data remittance Dynamic Maintenance, can add or delete the recipient of data flow in the life span of data flow at any time；

The bandwidth of propagation path and consumption of the data flow inside autonomous cloud is unifiedly calculated by main control server；

The head-end site on traffic propagation path is uniformly controlled by main control server to be forwarded data；

According to the actual propagation path of data flow, occur inside the same thin cloud one or more equipment need to receive or When forwarding the data flow, data flow is forwarded by head-end site.

The characteristics of cast communication mechanism is in more autonomous clouds includes at least one following:

Multicast address is unique inside autonomous cloud, and multicast address needs to replace when across autonomous cloud；

The multicast address and relevant information of each autonomy cloud independent maintenance oneself；

The main control server of each autonomy cloud is interacted by the agreement of autonomous networks, and Cooperative Maintenance is across autonomous cloud multicast number According to the information of stream；

Border router is responsible for the forwarding of multicast traffic stream and multicast address replacement when across autonomous cloud；

By each main control server be uniformly controlled the border router on traffic propagation path data are forwarded and Multicast address replacement.

In cast communication mechanism, the equipment for sending data flow is referred to as data source, receives the equipment of data flow and converges for data, Data source to data converge between propagation path be referred to as multicast link.

In multicast link, the data packet of transmission is multicast packets, the multicast packets that data source issues, may by one or After the forwarding of multiple head-end sites, reaches data and converge.

Head-end site is divided into head-end site and the borderline head-end site of autonomous cloud inside autonomous cloud. Head-end site inside autonomous cloud includes terminal sub-control server and boundary sub-control server.The autonomous borderline data of cloud Forward node is exactly border router.

When data source and data remittance belong to the same autonomous cloud, multicast packets are after data source sending, inside autonomous cloud Data are reached after the forwarding of one or more internal data forward node to converge.

When data source and data remittance belong to different autonomous clouds, multicast packets are after data source sending, first in data source Border router is reached after the forwarding of one or more internal data forward node inside place autonomy cloud, then on boundary Multicast address replacement is carried out on router, and multicast address is substituted for the latter multicast address jumped in autonomous cloud, is then proceeded to It is forwarded inside the autonomous cloud of latter jump, the position converged according to data, it may be necessary to be forwarded, pass through inside multiple autonomous clouds It crosses after one or more border routers carry out multiple address replacement and reaches autonomous cloud where data are converged, finally where data remittance Autonomous cloud reaches data by forwarding and converges.

In order to preferably describe cast communication, multicast traffic stream is known as since data source to the transmission path that data are converged Transmission path of the global multicast link inside each autonomous cloud is known as local multicast link by global multicast link.

Data source and data in global multicast link, which are converged, is also known as global data source and global data remittance.

Also the concept for having data source and data to converge in local multicast link, they are also known as local data source and local data It converges.

Global data source and global data remittance can be terminal, terminal sub-control server or boundary sub-control server.

Local data source and local data remittance can be terminal, terminal sub-control server, boundary sub-control server or side Boundary's router.

When local data source is terminal, it is called physical data source；When local data source be terminal sub-control server or When the sub-control server of boundary, it is called virtual data source；When local data source is border router, it is called relaying data Source.

When it is terminal that local data, which converges, it is called physical data remittance；When local data converge be terminal sub-control server or When the sub-control server of boundary, it is called virtual data remittance；When it is border router that local data, which converges, it is called relaying data It converges.

When multicast packets carry out multicast address replacement on border router, the multicast packets for replacing front and back belong to group all the way Multicast data stream.At this point, border router is both local data remittance and data remittance direction autonomy in data source direction autonomy cloud The local data source of cloud.

Multicast packets can also carry out multicast address replacement inside autonomous cloud, i.e., by the head-end site inside autonomous cloud Multicast address in multicast packets is substituted for another multicast address.At this point, the multicast packets of replacement front and back belong to different groups Multicast data stream.Multicast packets before replacement belong to old multicast traffic stream, and it is exactly old for carrying out the head-end site of address replacement The global data of multicast traffic stream is converged.Replaced multicast packets belong to new multicast traffic stream, and the data for carrying out address replacement turn Hair node is exactly the global data source of new multicast traffic stream.The head-end site for carrying out address replacement is both that data are converged It is data source.

Head-end site (terminal sub-control server, boundary sub-control server, border router) in forwarding multicasting packet, Determine how to forward by multicast guiding table inside inquiry and multicast information table.

1, multicast is oriented to table

Multicast guiding table has 4, No. 0, No. 1, No. 2 and No. 3 guiding table is referred to as, in terminal sub-control server, boundary No. 0, No. 1, No. 2 and No. 3 guiding table can be used in sub-control server, No. 1 and No. 2 guiding can be used in border router Table.

The entry number of every guiding table is equal to the maximum multicast traffic stream quantity supported in autonomous cloud, passes through multicast address It is indexed.

For example, could support up 1M multicast traffic stream in autonomous cloud, then the effective range of multicast address is exactly 0x00000000-0x000fffff, the entry number of every guiding table are also 1M.

The navigation information when multicast packets from No. 0 mouth are sent to No. 0 mouth is had recorded in the list item of No. 0 guiding table.

The navigation information when multicast packets from No. 0 mouth are sent to No. 1 mouth is had recorded in the list item of No. 1 guiding table.

In border router, the autonomous cloud (lower layer's autonomy cloud) that entry number is accessed by No. 0 mouth is determined.

The navigation information when multicast packets from No. 1 mouth are sent to No. 0 mouth is had recorded in the list item of No. 2 guiding tables.

In border router, the autonomous cloud (upper layer autonomy cloud) that entry number is accessed by No. 1 mouth is determined.

The navigation information when multicast packets from No. 1 mouth are sent to No. 1 mouth is had recorded in the list item of No. 3 guiding tables.

Navigation information includes guided mode and replacement address list.

Guided mode is 0 multicast packets for indicating the direction without sending, and indicates to need to send but do not need to carry out address for 1 Replacement, for 2 indicate need send and need to carry out single multicast address address replacement, for 3 indicate need send and need into The address replacement of the multiple multicast address of row.

The multicast address for carrying out address replacement is had recorded in replacement address list, when guided mode is 0 or 1 in table not Include 1 multicast address when guided mode is 2 comprising multicast address, includes multiple multicast address when guided mode is 3.

2, multicast information table

Multicast information table has 2, is referred to as No. 0 and No. 1 information table.The entry number of every information table is equal in autonomous cloud The maximum multicast traffic stream quantity supported, is indexed by multicast address.

Address information when multicast packets are sent to No. 0 mouth is had recorded in the list item of No. 0 information table.

Address information when multicast packets are sent to No. 1 mouth is had recorded in the list item of No. 1 information table.

Address information includes 256 bit altogether.256 bit correspond to 256 interfaces in thin cloud, and the position of bit is exactly The logic port address of interface.The numerical value of bit is 0 expression without sending the interface for multicast packets, and numerical value is that 1 expression needs to send out It is sent to the interface.

For example, the 3rd in 0x00012345 list item in No. 1 information table and the 7th bit are 1 to indicate multicast address Data packet for 0x00012345 needs while being sent to logic port address to be 0x03 and two of 0x07 when being sent to No. 1 mouth Network interface.

Data source concordance list is used for the corresponding multicast address of global equipment number and lane number lookup according to data source, such as Fruit, which can not find out, indicates that there is no corresponding multicast traffic streams in this autonomy cloud.

3, multicast routing table

Multicast routing table is used for transmission path of the record data stream in each thin cloud (master control thin cloud or sub-control thin cloud), often One list item corresponds to routing iinformation of the multicast traffic stream in some thin cloud.Multicast routing table by multicast address with it is micro- The mode of cloud number is searched, if can not find out indicate the corresponding multicast traffic stream of the multicast address not in corresponding thin cloud into Row transmission.

For thin cloud number for distinguishing different thin clouds, thin cloud number is defined as logical end of the manager of thin cloud in master control thin cloud Port address.

The list item of each multicast routing table is made of 256 bytes.Each byte corresponds to some network interface in thin cloud Routing iinformation, the position of byte in the table entry is exactly the logic port address of corresponding network interface.

When the numerical value of certain byte is 0 in list item, indicate that corresponding network interface does not receive this road multicast traffic stream.

When the numerical value of certain byte is the logic port address of corresponding network interface in list item, indicate that the interface is this road multicast Data source header of the data flow in corresponding thin cloud, i.e., the multicast packets of other interfaces directly or indirectly connect from this in thin cloud Mouthful.

When the numerical value of certain byte is other values in list item, indicate data on the interface corresponding to this numerical value Network interface.

It is an example of multicast routing table below:

Byte location	1	3	5	10	30	100	150
								Byte content	5	5	10	10	10	30	30

The first row indicates which byte in 256 bytes in above table, and the second row indicates the number at corresponding byte Value, unlisted other byte values are 0.

Assuming that above table indicated is routing of the data flow in 0x78 thin cloud that multicast address is 0x00001234 Information.

It could be aware that multicast packet of the data flow in 0x78 thin cloud that multicast address is 0x00001234 according to definition The source of stream from logic port address be 10 interface belonging to equipment X, then this road multicast traffic stream is forwarded by equipment X Equipment Z belonging to the interface that equipment Y and logic port address belonging to the interface for being 5 to logic port address are 30, equipment Y is again This multicast traffic stream is forwarded to two equipment belonging to the interface that logic port address is 1 and 3, equipment Z is then this data flow It is forwarded to two equipment belonging to the interface that logic port address is 100 and 150.

The transmission of multicast packets is realized by terminal sub-control server, boundary sub-control server and border router.

In another embodiment of the application, after step 1702, if global data remittance belongs to this autonomy cloud, sentence Whether disconnected global data remittance is terminal or terminal sub-control server or boundary sub-control server.

If so, determining that global data converges method, allow to continue to handle.

If not, it is determined that global data is converged illegally, is generated addition data remittance response, to notify generation mistake, is ended processing.

In another embodiment of the application, after step 1702, if global data remittance is not belonging to this autonomy cloud, It determines that global data is converged illegally, generates addition data remittance response, to notify generation mistake, end processing.

Step 1703, judge to converge in this autonomy cloud with the presence or absence of the addition data and request corresponding multicast traffic stream.

Multicast management module, which can search multicast traffic stream by data source concordance list, whether there is, then be believed by data source Breath table, which searches multicast traffic stream, whether there is.

If at least one finds multicast traffic stream and is not present in data source concordance list, data source information table, really The multicast traffic stream is not present in fixed this autonomy cloud.

If finding multicast traffic stream presence simultaneously in data source concordance list, data source information table, it is determined that this is certainly Control in cloud that there are the multicast traffic streams.

If there is multicast traffic stream, then can continue to handle.

If there is no multicast traffic stream, and global data source belongs to this autonomy cloud, then generate addition data converge response, with It notifies Service Processing Module that mistake occurs, ends processing.

Step 1704, it if there is the multicast traffic stream, is then converged according to the global data source and the global data The autonomous cloud of ownership determines that local data source and local data are converged in this autonomy cloud.

In oneainstance, if global data source belong to this autonomy cloud, if determine global data source be this autonomy cloud in Local data source.

In another scenario, if global data source is not belonging to this autonomy cloud, inquiry can route to global data source and return The autonomous cloud of category and the border router for belonging to this autonomy cloud, as the local data source in this autonomy cloud.

In another scenario, if global data remittance belongs to this autonomy cloud, it is determined that it is in this autonomy cloud that global data, which is converged, Local data converge.

Step 1705, the multicast traffic stream is set up in this autonomy cloud be transmitted to the local from the local data source The local multicast link that data are converged is transmitted to set up at least partly described multicast traffic stream from the global data source described complete The global multicast link that office data converges.

Multicast management module can be according to the local device number (local data remittance) and data source information that global data is converged Local data source equipment number (local data source) in table, calculate this addition data converge request multicast traffic stream this from The local multicast link in cloud is controlled, so that group build the global multicast link in autonomous networks in.

In one embodiment of the application, step 1705 may include following sub-step:

Sub-step 17053, the multicast link that the equipment for receiving local multicast chain road returns set up response.

Multicast management module can send corresponding multicast chain according to the device type of each equipment in local multicast chain road Order is set up on road, and multicast traffic stream is sent from local data source, is transmitted to local data by head-end site It converges, to open the local multicast link.

After the multicast link that multicast management module receives each equipment in local multicast chain road sets up response, update related Multicast table.

In the concrete realization, it includes data source STATUS control commands, multicast link control command that multicast link, which sets up order,； Therefore, it includes data source state control response, multicast link control response that corresponding multicast link, which sets up response,.

Wherein, data source STATUS control commands, data source state control response, can be used for controlling belonging to multicast traffic stream Terminal device whether send multicast traffic stream.

When multicast traffic stream is not by any data tandem time receiving, main control server, which can control its corresponding terminal, to be stopped Multicast traffic stream is sent, to reduce the flow on network.

When there is data tandem to receive the multicast traffic stream, then transmission group controlling its corresponding terminal by main control server Multicast data stream.

The PDU of data source STATUS control commands uses unicast packet transmission, and format can be as shown in the table:

The data packet for starting to send data source is indicated when operation code is 1.

The data packet for stopping sending data source is indicated when operation code is 2.

The PDU of data source state control response uses unicast packet transmission, and format can be as shown in the table:

Information element	Existence	Format	Length	Description
					Operation code	M	V	4
Multicast address	M	V	4	The multicast address of multicast traffic stream
					Response results	M	V	4	0=success, other=failure
Message error detection code	O	TLV	4

Multicast link control command, multicast link control response can be used for main control server control local multicast link Reception, duplication and the transmission of upper multicast traffic stream.

10: opening the data channel of No. 1 multicast information table

11: closing the data channel of No. 0 multicast information table

12: closing the data channel of No. 1 multicast information table

13: removing the data channel of No. 0 multicast information table

14: removing the data channel of No. 1 multicast information table

Comprising the multicast address before multiple replacements in native multicasting address list, number is identical with operation code number.

Replacing includes multiple replaced multicast address in multicast address list, and number is identical with operation code number.

It include multiple logic port addresses in logic port address list, number is identical with operation code number.

When some operation code in opcode list is 1-4, native multicasting address list and replacement multicast address list In corresponding table item it is significant.It can be led to specific multicast according to information such as operation code, native multicasting address, replacement multicast address A replacement is added into the replacement address list of the particular entry (being determined by native multicasting address) of table (being determined by operation code) Address (is determined) by replacement multicast address.

When some operation code in opcode list is 5-8, native multicasting address list and replacement multicast address list In corresponding table item it is significant.It can be led to specific multicast according to information such as operation code, native multicasting address, replacement multicast address A replacement is deleted into the replacement address list of the particular entry (being determined by native multicasting address) of table (being determined by operation code) Address (is determined) by replacement multicast address.

When some operation code in opcode list is 9-10, native multicasting address list and logic port address list In corresponding table item it is significant.Specific multicast can be believed according to information such as operation code, native multicasting address, logic port addresses The specific bit ceased in the particular entry (being determined by native multicasting address) of table (being determined by operation code) (is determined by logic port address It is fixed) it is set as 1 (starting to send).

When some operation code in opcode list is 11-12, native multicasting address list and logic port address column Corresponding table item in table is significant.It can be by specific multicast according to information such as operation code, native multicasting address, logic port addresses Specific bit in the particular entry (being determined by native multicasting address) of information table (being determined by operation code) is (by logic port address Determine) it is set as 0 (stopping sending).

When some operation code in opcode list is 13-14, the corresponding table item in native multicasting address list is intentional Justice.It can be by the particular entry of specific multicast information table (being determined by operation code) according to information such as operation code, native multicasting addresses Whole bit in (being determined by native multicasting address) are set as 0 (stopping sending).

The PDU of multicast link control response uses unicast packet transmission, and format can be as shown in the table:

					Opcode list	M	TLV
Response results	M	V	4	0=success, other=failure
					Multicast address list	C	TLV	Native multicasting address information
Multicast address list	C	TLV		Replace multicast address information
					Logic port address list	C	TLV
Message error detection code	O	TLV	4

In oneainstance, it if the equipment of local multicast chain road is local data source and is terminal, is sent to equipment Data source STATUS control commands, with start send multicast traffic stream.

In another scenario, if the equipment of local multicast chain road be local data source and be terminal sub-control server or Boundary sub-control server then sends the multicast link control command, the transmission channel to open multicast traffic stream to equipment.

In another scenario, if the equipment of local multicast chain road is local data source and is border router, to Equipment sends multicast link control command, the transmission channel to open multicast traffic stream；

In another scenario, if the equipment of local multicast chain road is head-end site, multicast is sent to equipment Link control command, the transmission channel to open multicast traffic stream.

In another scenario, if the equipment of local multicast chain road be local data converge and be terminal sub-control server or Boundary sub-control server, then judge whether multicast traffic stream services specified multicast service.

If the specified multicast service of service, multicast link control command is sent, to equipment to start multicast packet The multicast address of stream replaces with specified multicast address.

For multicast services such as video conferences, the operation such as spokesman's (terminal) is switched over regularly, so that regular Ground changes simultaneously the multicast traffic stream that great amount of terminals is watched, in order to reduce the communication overhead between head-end site, eventually Multicast address in the multicast service can be replaced with specified multicast address by end sub-control server or boundary sub-control server.

Terminal sub-control server or boundary sub-control server are both data remittance when carrying out the replacement of multicast address, and Data source, since terminal sub-control server or boundary sub-control server can carry out the multicast address of multichannel multicast traffic stream simultaneously Replacement therefore pass through different channel number and distinguish the replaced multicast traffic stream in address.

In another embodiment of the application, step 1705 may include following sub-step:

5, data are deleted for terminal T22 to converge

Assuming that the 1st road of terminal T22 and the 2nd circuit-switched data channel is needed no longer to receive the 1st He of terminal T21 in operation flow 2nd road multicast traffic stream, then the Service Processing Module of main control server A2 sends the 1st circuit-switched data to multicast management module first and converges Deletion data converge request, it is 60031-60021-00022-00000 (terminal that the global data in request, which converges global equipment number, The global equipment number of T22), global data Correspondent Taoist monastic name be 1, global data source overall situation device number code bit 60031-60021- 00021-00000 (the global equipment number of terminal T21), global data source channels number are 1.

After multicast management module receives deletion data remittance request, discovery global data source belongs to this autonomy cloud and device type For terminal, discovery global data remittance belongs to this autonomy cloud and device type is terminal.

Multicast management module finds that multicast traffic stream exists, and calculates local data source T21 and local data remittance T22 Between local multicast link be terminal T21 → terminal sub-control 21 → terminal of server B T22.

Multicast management module search multicast routing table, obtain multicast address be 0x00000001, the table that thin cloud number is 0x21 , find that terminal T22 is receiving this road multicast traffic stream and carrying out self terminal sub-control clothes without the reception of other equipment really after analysis The data of business device B21, then send multicast link control command to terminal sub-control server B 21, it is desirable that it stops from No. 0 mouth handle The multicast traffic stream that multicast address is 0x00000001 is sent to equipment (the configuration multicast information that logic port address is 0x22 Table), it is simultaneously stopped and the multicast traffic stream that the multicast address from No. 0 mouth is 0x00000001 is sent with identical multicast address To No. 0 mouth (configuration multicast is oriented to table).

The above-mentioned multicast routing table list item of multicast management module check is found at this time in addition to terminal sub-control server B 21, other Terminal does not all receive this multicast traffic stream, i.e., without data in thin cloud belonging to the mouth of terminal sub-control server B 21 No. 0 It converges, then needs to check whether there are also data to converge in thin cloud belonging to No. 1 mouth of terminal sub-control server B 21, thin cloud belonging to No. 1 mouth is Master control thin cloud, so requiring to look up the list item that multicast address in multicast routing table is 0x00000001, thin cloud number is 0xfb, as a result There is no this list items, i.e., also converge without data in thin cloud belonging to the mouth of terminal sub-control server B 21 No. 1, should just close at this time Terminal T21 is to the transmission path between terminal sub-control server B 21, so data source STATUS control commands are sent to terminal T21, It is required that terminal T21 stops sending the multicast traffic stream that multicast address is 0x00000001.

After terminal sub-control server B 21 receives multicast link control command, the of No. 0 multicast information table is set The 0x22 bit of 0x00000001 list item is 0, inquires the 0x00000001 list item of No. 0 multicast guiding table, finds guiding module Formula is 1 (sends and do not replace), then it is 0 that guided mode, which is arranged, then sends multicast link control response and gives main control server A2.

After terminal T21 receives data source STATUS control commands, stop sending the data flow that multicast address is 0x00000001, Then it sends data source state control response and gives main control server A2.

Multicast management module receives the multicast link control response of terminal sub-control server B 21 and the data of terminal T21 The corresponding table item in multicast routing table is deleted after the state control response of source, is then sent to delete data and converge to Service Processing Module and be rung It answers.

Service Processing Module converges to the deletion data that multicast management module sends the 2nd road multicast traffic stream requests, multicast pipe Discovery needs to send multicast link control command to terminal sub-control server B 21 after managing resume module, it is desirable that it stops from No. 0 mouth The multicast traffic stream that multicast address is 0x00000002 is sent to equipment (the configuration multicast information that logic port address is 0x22 Table), it is simultaneously stopped and the multicast traffic stream that the multicast address from No. 0 mouth is 0x00000002 is sent with identical multicast address To No. 0 mouth (configuration multicast is oriented to table).

Multicast management module is found that while not other in the thin cloud belonging to No. 0 mouth of terminal sub-control server B 21 Recipient, but there are also other recipients in the thin cloud belonging to its No. 1 mouth, so terminal T21 cannot be closed to terminal sub-control Transmission path between server B 21.

Terminal sub-control server B 21 is handled after receiving multicast link control command, then sends multicast link control Respond to main control server.

Multicast management module receives after the multicast link control response of terminal sub-control server B 21 to Service Processing Module It sends and deletes data remittance response.

Service Processing Module receives to delete notifies terminal T22 no longer to receive reception group after data remittance responds by operation flow Broadcast the multicast traffic stream that address is 0x00000001 and 0x00000002.

6, data source is destroyed for terminal T21

Service Processing Module issues 2 destruction data source requests to multicast management module, and the data source types in request are 1, overall situation equipment number in global data source is the global equipment number of terminal T21, global data source channels number are respectively 1 and 2.

Multicast management module passes through discovery of tabling look-up and the multicast traffic stream destroyed is needed all to exist.

The multicast traffic stream for being 0x00000001 for multicast address, it can be found that terminal is not present in multicast routing table The list item of thin cloud where T21, i.e., no other data are converged.So the list item in data source concordance list is directly deleted, by data source The data source state of information table list item is set as 0.

The multicast traffic stream for being 0x00000002 for multicast address finds exist in multicast routing table corresponding to terminal The list item of thin cloud where T21, i.e., there are also other recipients, so this multicast traffic stream cannot be destroyed.

Multicast management module sends 2 destruction data source responses to Service Processing Module, respectively indicates the 1st destruction data Source request handle successfully, the 2nd destruction data source request processing failure.

Service Processing Module, which receives to destroy after data source responds, continues follow-up business process.

Example four configures multicast link (having multicast address replacement inside autonomous cloud) in Dan Zizhi cloud

If participating in the equipment in certain operation flow includes terminal T21, terminal T22, terminal T23, terminal T24, terminal T25, terminal T26 and terminal sub-control server B 22, wherein each terminal is configured to transmittable 2 road multicast traffic streams, can connect 3 road multicast traffic streams are received, terminal sub-control server B 22 is configured to need to replace 3 road multicast traffic streams.
