Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
As long as in addition, technical characteristic involved in invention described below different embodiments non-structure each other
It is be combined with each other into conflict can.
Fig. 1 shows two kinds of application scenarios, and wherein transmitting terminal 11 is used to send business datum, and receiving terminal 13 is used to receive industry
Business data, equipment 12 are used to perform business datum interrupted transmission method provided by the invention.Two kinds of application scenarios differences
It is, the first is that transmitting terminal 11 is directly connected to receiving terminal 13 by major network 14, and equipment 12 is in parallel with major network, and standby by four
Net 15 is connected with receiving terminal 13;Second is that transmitting terminal 11 connects equipment 12 by major network 14, and equipment 12 is connected by major network 14
Receiving terminal 13, three is series relationship, while equipment 12 is connected by four standby nets 15 with receiving terminal 13.
Above-mentioned major network and the network that can be identical or different type for net, and its communication media, network bandwidth, communication
Speed may each be different, and major network 14 and standby net 15 can for example include computer network, optical transmission communication network, satellite and lead to
Communication network and radio short wave communication network etc..In the present invention, multiple bearer networks include computer network, optical transport communication network
Network, satellite communication network and radio short wave communication network etc..Simplified in Fig. 1 in order to highlight the annexation of three terminals
Network internal concrete structure is, it is necessary to explanation, between major network 14 and standby net 15, security isolation between each standby net 15, not mutually
Influence does not produce routing relation.
Equipment 12 is the data insertion equipment positioned at IP network end, can support a variety of marks such as RJ-45, E1, RS-232
Quasi- communication interface, can connect simultaneously a variety of heterogeneous communications networks such as computer network, optical transport special line, satellite special line, shortwave or
Dedicated channel, all kinds of different communication protocols are uniformly converted into ICP/IP protocol, realize heterogeneity, different type, different band
Wide bearer network or dedicated channel it is hot standby draw connect, and realize the strategy switching of each bearer network.User's application system only needs
To be connected with the general service interface of equipment 12, it is not necessary to directly come into contacts with specific communication network, can greatly simplify user should
With the institutional framework of system data transmission layer, reduce application system installation and deployment and ensure maintenance difficulties.
The present embodiment provides a kind of business datum interrupted transmission method, and this method can be held by the equipment 12 in Fig. 1
OK, as shown in Fig. 2 this method comprises the following steps:
S1, obtain major network in business datum characteristic information, characteristic information can include business datum various parameters,
Flow etc..Preferably, " five-tuple " is used as characteristic information, the i.e. source address of business datum, destination address, transmission by the present embodiment
Five layer protocol type, source port number and destination slogan parameters, this five parameters can be extracted from the heading of business datum,
The data of IP headings are obtained, can't check or change upper layer application data, ensure that the safety of data transfer.In addition, also
Traffic statistics can be carried out to business datum, can specifically be counted based on two dimensions, i.e., based on port or based on business.
When carrying out traffic statistics based on port, the ether network packet that each physical port is received and sent is monitored, and by per second fixed
When computation of Period byte-rate.When carrying out traffic statistics based on business, the Ethernet for receiving and sending per a kind of business is monitored
Message, and calculate byte-rate by timing cycle per second.
S2, detects the network state of the major network and at least one standby net, namely by monitoring network transmission channel can
Up to property and transmission quality, so that it is determined that the state of each network.
The step for can carry out in real time, specifically, the on off operating mode of network path is judged, by it is local with it is remote
The handshake operation of " end-to-end " (End-to-End) determines between the uninterrupted network system equipment at end.Path can have four kinds can
The state of energy:It is unobstructed, disconnect, deterioration and it is unknown.Handshake operation is not needed between the website that need not be communicated, path status is not
Know;State between the website for needing to communicate is unobstructed, disconnection or deterioration.Uninterrupted network system equipment can be periodically sent out
Whether path of the heartbeat message between real-time two websites of dynamic surveillance be unimpeded.When detecting site-local within a period of time
There is no IP data packet communications between remote station or after channel quality drops to threshold value, can disconnect automatically local with distal end two
Connection between individual uninterrupted network system equipment, stops handshake operation.Establishment of connection and dismounting all should be automatically on demand
Carry out.
S3, major network and/or at least one standby net transmission institute are passed through according to the characteristic information and network state selection
State business datum.This step purpose is to consider " business datum content " and each network " current state " the two factors,
With selection by major network and/or standby net come transmission services, " business datum content " is determined by characteristic information, and user can be with
" transmission strategy " is pre-set, namely pre-set miscellaneous service data to be transmitted by which or several networks.
For a user, business datum can be classified, such as can be divided into control class business datum, regarding/sound
Frequency business datum and other business datums (business datum in addition to above two), and for a user, miscellaneous service
The significance level of data is different, so user can pre-set the transmission strategy for miscellaneous service data.It is such as heavy
The business datum that degree is higher is wanted, the mode of major network and standby net simultaneous transmission (active and standby simultaneous interpretation) should be taken;For secondary industry
Business data, it can just select to be transmitted (the disconnected standby biography of master) by standby net only in the case where major network disconnects or deteriorates;For it
His business datum, can be ensured, different systems communication network takes different weighted values according to weighted fair queuing algorithm.
Transmit tactful not limited to this, can flexibly be set according to user's request during practical application, will subsequently be directed to transmission strategy carry out it is detailed
It is thin to introduce.
Under series system in Fig. 1, the transmission of business datum can arbitrarily control in multiple networks, such as preferentially exist
Transmission services data in major network, once detect that major network is unavailable, then cut-in stand-by network transport service data.This mode class
Like multirouting backup protection, but it is more simpler than Routing Protocol, it is not necessary to the routing protocol packet of multicast is sent, avoids standby usage
Mutually study is route between network.Major network and standby net can be it is separate, can although being all connected directly between in equipment
To accomplish the security isolation between network.
In Fig. 1 under parallel way, the effect for switching transmission means can be understood as auxiliary protection, and now it can not
Whether limit service data by mirror-image fashion monitor flow major network in main transfers on network, once detect major network
Unavailable, then mirroring service data can be from standby net transmission, and after major network recovers, mirroring service data can be then dropped.This
The advantages of kind mode is need not to make change physically to former major network, will not increase trouble point, simply in Restoration stage, having can
Major network can occur and standby net transmits the business datum of repetition, for most of IP operations, duplicate message can't produce any
Influence.
For performing the equipment of this method, business datum sort operation need not be actually carried out, and can be passed through
The corresponding relation of characteristic information and predetermined policy determines transmission means, such as can pre-set (five yuan of multigroup characteristic information
Group information), every group of characteristic information (five-tuple information) is corresponding with transmission strategy (active and standby simultaneous interpretation or main disconnected standby pass), when getting master
During the characteristic information of the business datum in net, it can be determined that whether it meets one kind in the multigroup characteristic information pre-set,
Then corresponding transmission strategy is taken to be transmitted.
Multiple two layers of Ethernets or three layers of IP network are connected as bearer network simultaneously, collect the upper of end local net network
Row flow, analyzes class of service, and strategy determines IP bag business datum priority, monitors standby usage COMMUNICATION NETWORK PERFORMANCES matter in real time
Amount, dynamic judge the accessibility by each bearer network to destination website, once working channels break down or bandwidth occurs
Mutation, starts handover mechanism, uplink traffic is switched between multiple bearer networks immediately, meanwhile, by each bearer network
The downlink traffic sent is sent to the main frame in LAN, ensures that high-priority service high priority data passes through.
When the heterogeneous networks such as optical transport, satellite, shortwave access jointly, it is ensured that when primary network breaks down, core industry
Business can take over seamlessly spare communication network, realize the uninterrupted communication of core business.Uninterrupted network system equipment can be with
Be deployed in the network computer room of constituent parts, IP network be connected to by Ethernet interface, by E1 or RS232 interface connect optical transport,
The transmission channels such as satellite, shortwave, centre grade and hinge level equipment can be used with networking, and end stage equipment should using ad hoc mode
With with the common guarantee to core business, it is ensured that core business communicates uninterrupted.
According to business datum interrupted transmission method provided by the invention, by detecting the business datum transmitted in major network simultaneously
Its characteristic information is obtained, and monitors the state of major network and standby net in real time, selects to transmit miscellaneous service by major network and/or standby net
Data, user can define type of service and priority level according to being actually needed, so that equipment takes active and standby simultaneous interpretation or main disconnected
It is standby the strategy such as to pass to transmit miscellaneous service data, realize the steady switching and highly reliable between multiple bearer networks of core business data
Uninterrupted communication.
Three kinds of preferable transmission strategies are present embodiments provided, as a preferred embodiment, above-mentioned steps S3 can
With including following sub-step:
S31A, judges whether the characteristic information is consistent with presupposed information, when the characteristic information is consistent with presupposed information
When, perform step S32A.
S32A, the business datum is replicated, in parallel in Fig. 1 in the case of, duplication herein should be understood to that mirror image is grasped
Make, i.e., the business datum transmitted in major network is mirrored in equipment;For the in the case of of being connected in Fig. 1, due to the business in major network
Data will necessarily pass through equipment, actually belong to replicate operation.
S33A, select the business datum of at least one standby net transmission copying.
Such scheme is the transmission strategy of " active and standby simultaneous interpretation ", i.e., by the major network in connection status and at least one standby
Net is transmitted to business datum simultaneously.This transmission strategy goes for video/audio business datum and timing requirement not
Above-mentioned presupposed information can be arranged to and video/audio business datum and general service by high general service data, user in advance
The information that data are consistent, such as transmitting terminal port transmission known to user is necessarily video/audio business datum, then can be advance
Set port information, when get carry out the business datum of port since then when, i.e., using above-mentioned " active and standby simultaneous interpretation " transmit strategy.
Transmission services data can not have packet loss in the standby net switching of major network by way of " active and standby simultaneous interpretation ", it can be ensured that
The real-time Transmission of business datum, while the business data packet of repetition can be eliminated in receiving terminal.The transmission means of " active and standby simultaneous interpretation "
Focus on ensureing not lost data packets, might not can ensure the sequential of its packet transmitted, it is therefore " active and standby same
The transmission means of biography " is not particularly suited for the transmission that timing requires higher control class business datum, because control class business number
According to not allowing out of order submission.For such as video conference and networking telephone data, as long as ensureing not to be delayed does not lose packet, make
Its transmission requirement is disclosure satisfy that with the transmission means of " active and standby simultaneous interpretation ".
As second of preferred embodiment, above-mentioned steps S3 can include following sub-step:
S31B, judges whether the characteristic information is consistent with presupposed information, when the characteristic information is consistent with presupposed information
When, perform step S32B.
S32B, judge whether the major network is abnormal, when major network is normal, can keep by major network transmission services data,
When major network exception, step S33B is performed;
S33B, replicate the business datum.
S34B, the business datum of at least one standby net transmission copying is selected, one or more standby nets can be selected, selection
According to bandwidth, current state that can be standby net etc..
Above-mentioned preferred scheme is " main disconnected standby biography " transmission strategy, and this transmission strategy goes for ageing requirement
Above-mentioned presupposed information can be arranged to the letter with controlling class business datum to be consistent by higher control class business datum, user in advance
Breath, such as certain transmitting terminal transmission known to user is necessarily control class business datum, then can pre-set transmitting terminal IP information,
When get carry out the business datum of transmitting terminal since then when, i.e., using above-mentioned " main disconnected standby pass " transmission strategy.
Because control class business datum is to need the key business of high reliability transport, out of order submission is not allowed especially
Business datum.In LAN environment, seldom there is out of order and data loss problem.If the computer for receiving data is in remote
End station point, UDP message will pass through complicated IP network, then the out of order and probability of packet loss is with regard to much larger.When network load reaches
Certain limit, it is common that intermittent congestion, which causes UDP datagram to be dropped,.In the case of using above-mentioned transmission strategy,
A similar TCP reliable transmission tunnel can be built by sliding window protocol between two uninterrupted network system equipments
Road, it is responsible for the Retransmission timeout of data and out of order correction problem.It is exactly specifically the message mirror principle using interchanger, institute
The uplink traffic for having business is mirrored to uninterrupted network system equipment.
As the third preferred embodiment, above-mentioned steps S3 can include following sub-step:
S31C, judges whether the characteristic information is consistent with presupposed information, when the characteristic information is consistent with presupposed information
When, perform step S32C.
S32C, the business datum is cached, independent memory headroom can be used by performing the device interior of this method, be used
The mode of FIFO is data cached, and can clear up cache contents on time.
S33C, judge whether the major network is abnormal, can be kept when the major network is normal by major network transmission services number
According to;When major network exception, step S34C is performed.
S34C, replicate the business datum;
S35C, available standby net being determined whether, when available standby net be present, at least one standby net transmission copying can be selected
Business datum;When in the absence of available standby net, step S36C is performed.
S36C, the state of major network and standby net is monitored, until when having available network, passes through the business of available network transmission buffer
Data.
According to above-mentioned preferred scheme, the packet loss enabled after being disconnected monitoring major network before standby net can autonomous retransmission
Recover.Even major network and standby net simultaneously switches off a bit of time (such as in 30 seconds), site-local uplink traffic number to be sent
It is buffered according to that can be lined up in equipment, waits one of subsequent major network or standby net to recover communication, then transfer data to other side.
Mechanism can be resumed using above-mentioned caching for very important control class business datum, the mechanism is able to ensure that i.e.
Make major network, standby net at the same break down (such as fault time is less than 30s) when business datum do not lose.
On above-mentioned steps S33A and S34B, when the quantity of standby net is multiple, the present embodiment is only standby from one of them
Net transmission services data, that is, comprise the following steps:
Judge whether there is available standby net in multiple standby nets according to the network state information;
When having available standby net in the multiple standby net, the business datum of an available standby net transmission copying is selected.
Further, a standby net with optimum state is selected according to the network state information;
Pass through the business datum of the standby net transmission copying with optimum state.
Above-mentioned optimum state can integrate many factors and be determined, such as according to packet loss, total bandwidth etc., actual use
When can be configured as the case may be.
Determining the mode of network state has a variety of, has multiple steps to need to be determined network in method provided by the invention
The operation of state, by taking above-mentioned steps S2 as an example, it can specifically comprise the following steps:
S21, detecting periodically message is sent by network under test;
S22, message queue record is established according to the detecting periodically message, the message queue record includes the spy
Observe and predict transmission time and the sequence of message number of text;
S23, monitor whether to receive response message;
S24, when receiving response message, the major network is judged according to the response message and message queue record
Whether the network state with least one standby net is connection status.
Further, above-mentioned steps S24 may include steps of:
S241, the reception time of the response message and sequence of message number are compared with message queue record;
S242, the time delay of the detecting periodically message is calculated according to comparison result;
S243, according to the sum of the time delay of the detecting periodically message and probe messages, calculate packet loss;
S244, according to the packet loss, whether the network state for judging the major network and at least one standby net is connection shape
State.
After above-mentioned steps S3 determines transmission network, the total bandwidth of selected network can also be divided, to draw
Point subband it is wide transmit various types of business datums respectively, to ensure the transmission quality of important business data.In above-mentioned steps
Using the business datum of queue storage replication, in the present embodiment, all kinds of business datums are preferably stored respectively using multiple queues,
Specifically, the present embodiment stores the business datum of four types using four queues respectively, and Details as Follows:Q queues storage is absolute
The data of priority business type, such as mandatory business datum, Industry Control class business datum, ensure class requirement highest;Q1 teams
The chronesthesy business datums such as row storage video conference, the networking telephone, ensure that grade is taken second place;Q2 queues storage responsible consumer it is non-when
Quick property business, ensure grade third;Q3 queues store general service, no Special Safeguard requirement.
It can also comprise the following steps after step s 3:
Step S4, it is all kinds of traffic assignments network bandwidths according to the network state information of communication network.Pass through communication network
Network state information, such as bandwidth, packet loss and time delay, judge the communication quality of communication network, and then select communication to ensure plan
Slightly, i.e., whether distribute bandwidth and how to distribute bandwidth.
First, the bandwidth of communication network is considered.It is less than 2M (the 3rd preset range) channel for bandwidth, it is not necessary to divide band
Width, only transmit the business datum of first priority type of service;It is higher than 100M channel for bandwidth, according to default communication
Ensure that strategy distributes the communication bandwidth of fixed proportion for different types of business datum.When the bandwidth of channel is too low, such as 2M or low
When 2M, to ensure the communication security of mostly important core business, Q queuing datas are only transmitted, give up other data.
, can be according to the communication band of the fixation distributed during such as 100M or higher than 100M (the first preset range) when the bandwidth of channel is higher
Width transmission Q queuing datas, such as 100M networks are that Q queues retain 2M bandwidth, and 1000M networks are that Q queues retain 10M bandwidth;q1
~q3 queuing datas share remaining communication bandwidth according to fixed weight proportion, and the ratio can be 2:3:5.The communication network of high bandwidth
For network in transmission services data, the bandwidth retained for Q queues is not very big, and its reason is mandatory what is stored in Q queues
Though business datum is the business of user's core the most, the bandwidth that general this kind of data take is relatively low, no more than 1Mb/s.For
The purpose of mandatory business datum communication reliability is ensured, the communication network of high bandwidth still needs to retain bandwidth for Q queues.
Secondly, the packet loss and time delay of communication network are considered.When the packet loss in network state information is more than default lose
Bag rate threshold value, or when delay in the network information is more than default delay threshold, switch communication network.Use losing for communication network
Bag rate and time delay judge the quality of network.When packet loss is 100%, network blocks;When packet loss is more than 20%, network quality
Deterioration is serious;When time delay is more than 120ms, most of business is unavailable.This three kinds of situations assert that network is unavailable, need to carry out network
Switching.
Step S5, all kinds of business datums are transmitted by the network bandwidth of distribution respectively.The business provided according to the present embodiment
Data adaptive transmission method, before being transmitted using the communication network of determination to business datum, first to communication network
Distribute bandwidth, business datum according to type it is determined that network bandwidth in transmit.The type of business datum and its importance and right
Its communicate priority it is directly related, avoid prior art by whole communication data packet equalitys treat caused by communication network
The situation of the data transfer of delay or omission core business in the case of network Quality Down.By identifying core business data and right
Its priority communication, it is ensured that the reliability of core business data communication.
As a preferred embodiment, above-mentioned steps S4 may include steps of:
Step S41:Determine network bandwidth.As a width of N*2Mb of the band of communication network (N > 1), and bandwidth is in 2M-100M models
Enclose (the second preset range) it is interior when, perform Dynamic Bandwidth Allocation strategy.
Step S42:The network bandwidth of a setting value is reserved for the business datum of first priority type of service.Refer to for guarantee
The purpose of order property business datum communication reliability for the Q queues where the business datum of first priority type of service, it is necessary to retain
Certain bandwidth.Because the bandwidth that the mandatory business datum stored in Q queues takes is relatively low, no more than 1Mb/s, therefore definitely
The reserved network bandwidth of the business datum of priority business type need not be large, and typically may be set to 1Mb, that is, disclosure satisfy that communication can
Required by property.
Step S43:Dynamic bandwidth weight is distributed for the other kinds of business datum in addition to first priority type of service.
The change of bandwidth and packet loss of the network bandwidth weight in network state information and change.
Table 1
Step S44:It is the other kinds of business datum in addition to first priority type of service according to dynamic bandwidth weight
Distribute network bandwidth.Other kinds of business datum in addition to first priority type of service is shared remaining after step S42
Bandwidth, it is dynamic for the distribution of q1~q3 queuing datas using the dynamic bandwidth weight ratio shown in table 1 in an embodiment
State bandwidth.
Can be different communication priority and number in the case where network communication quality changes according to above-mentioned preferred scheme
