Abstract
A method for subdividing a primary network data flow into a plurality of subflows is disclosed. Each of the subflows is assigned a unique class of service or priority value. Tokens are allocated from the primary flow to each of the subflows to regulate the transmission of data over the network in such a way that the highest priority packets receive a higher transmission priority.
Description
Technical field
Present invention relates in general to communication system, and be specifically related to therein server data stream is subdivided into the communication system of a plurality of son streams.
Background technology
Can reach under the speed of 56Kbps by the telephone modem access internet today.Modulator-demodulator based on phone carries out modulation and demodulation in order to send by the telephone network based on speech bandwidth with data-signal.On the contrary, cable modem (cablemodem) provides by cable television system and has inserted the Internet, and this system has higher bandwidth, thereby can move under the data rate higher than telephone system.Cable modem provides being connected between subscriber computer and the cable system headend, on this aspect, cable operated person provide process (such as) the T1 line, to the access of the Internet.In cable system, the data that send to the computer user from the network data transponder are called as downstream data flow; The data that send to the network data transponder from the user are called as upstream.
Figure 1 illustrates the block diagram of the two-way cable system of schematic prior art.The cable system of prior art comprises data transfer equipment 101, Hybrid Fiber Coax (HFC) cable line 103, a plurality of cable modems 105 and 106 (illustrating two), with by respective communication link 116 and the 117 a plurality of user communication devices 107,108 (illustrating two) that are connected with 106 with cable modem 105. User communication device 107 and 108 for example can comprise, computer, TV or phone.Know as those of ordinary skills, headend equipment 101 comprises processor, router, interchanger, broadband downstream transmitter, uplink receiver, decomposer, synthesizer, customer data base, Network Management Station, DHCP (DHCP) and trivial file transfer protocol (TFTP) server, Call Agent, media gateway and accounting system.HFC cable line 103 comprises fiber optic cables, coaxial cable, optical fiber/coaxial node, amplifier, filter and tap, they support to send to cable modem 105 and 106 from headend equipment 101 by sharing down channel 110, and support to send to headend equipment 101 from cable modem 105 and 106 by the up channel of sharing 112.Programme signal is input in the headend equipment 101, is used for through HFC cable line 103 to users broadcasting.
The modulation of the special type on being used for each channel 110 and 112, each channel 110 and 112 common trait are to introduce other protocol requirement.For example, because down channel stream 110 is shared, descending protocol comprises addressing information, and each cable modem 105 and 106 is the information block supervision down channel stream 110 to its addressing.The information block that only is addressed to particular cable modulator-demodulator 105 or 106 (or being additional to communication equipment 107 or 108) or is addressed to all cable modems 105 or 106 (or being additional to communication equipment 107 or 108) (for example broadcast) is handled by cable modem 105 and 106, and sends to relevant user communication device 107 or 108 (for example phone, PC or terminal equipment) when appropriate.Because up channel stream 112 is shared, up channel stream access protocal is used to reduce the possibility that the communication information sent from cable modem 105 and 106 clashes.Exist some many access protocals to define up channel stream visit, comprise for example ALOHA of known agreement, time slot A LOHA, code division multiple access (CDMA), time division multiple access (TDMA) has the TDMA and the carrier sense multiple access (CSMA) of collision detection.
The uplink and downlink channel agreement of definition in data cable system interface standard (DOCSIS) version of publishing recently 1.0 is observed and used in some duplex cable systems, all proposes this standard as a reference at this.By the defined up agreement of DOCSIS standard is the TDMA method, wherein regularly, and by the time mark synchronization message of emission on the down channel stream 110 receive timed sending to cable modem 105 and 106 by headend equipment 101 (in the DOCSIS standard, being called " cable modem termination station " (CMTS)) control.Therefore, for make uplink communication can with the order, mode is carried out efficiently, before modulator- demodulator 105 and 106 begins the information that is provided by user communication device 107 and 108 is provided, reference time in each cable modem 105,106 must be synchronous basically with the similar reference time in headend equipment 101; Otherwise, send and may conflict mutually with information transmission from another modulator-demodulator 106 from the information of a modulator-demodulator 105.
Usually, headend equipment 101 through suitable communication link (for example Fiber Distributed Data Interface (FDDI) link or 100baseT Ethernet link) with link to each other such as the extranets 114 of Public Switched Telephone Network or such as the wide area Packet Based Network of the Internet.
Fig. 2 is the cable system assembly block diagram at user site place relevant with communication equipment 108.Under user's situation, 134 pairs of entering signals from cable system headend 101 of decomposer are decomposed.TV programme signal is being presented on the TV 140 under the control of set-top box 138.The connection of cable modem 105 is provided from second output of decomposer 134.To offer RF (radio frequency) tuner 142 from the downstream signal stream of headend equipment 101, this tuner modulator-demodulator power on or configuration phase during be tuned on the frequency range of distributing to cable modem 105.As mentioned above, typically, down channel stream uses quadrature amplitude modulation (qam), its in demodulator 144 by demodulation.Be input to MAC controller 146 by the signal of demodulation.Base-band data signal from MAC controller 146 is input to data and the control logic unit 148 that control cable modulator-demodulator 105 whole operation also further provide the Data Control function.Communication equipment 108 links to each other with control logic unit 148 with the data of cable modem 105, is used to be received in the data that down direction sends, and sends data at up direction.
Upstream from communication equipment 108 to data and control logic unit 148, MAC controller 146 pass through, and finally arrive modulator, to modulate.Typically, upstream is used Differential Quadriphase Shift Keying (DQPSK) or 16-ary QAM modulation.Being chosen in the configuration information that offers each cable 105 of modulation type is provided with.Upstream data is by decomposer 134, to send data through hybrid fiber/coaxial circuit 103 to headend 101.At last, data arrive external network 114, as in conjunction with Fig. 1 discussed.
In one embodiment, down channel use 64 or 256QAM modulate it and can transmit nearly 30 to 40Mbps data on the cable channels of 6MHz.Up channel uses QPSK or 16QAM signaling, and it has the available data rate from 320Kbps to 10Mbps.The uplink and downlink data rate is all disposed by system operator.For example, can be configured on both direction, receive and the transmission data by the employed cable modem 105 of business user with relative higher data speed.On the other hand, the resident can be configured to cable modem 105 visit (and therefore higher data rate is arranged) in the wider bandwidth that has of down direction, be used for receiving data, on the upstream data sending direction, it be limited in than low rate simultaneously from external network 114.In another embodiment, data rate allocation can be a time-sensitive.
Yet should emphasize that cable modem uses modulation type in advance to go up operation at given chip rate (or data rate).The priority of packet does not influence the upstream data rate or the bandwidth of configuration separately.All modulator-demodulators use identical bit rate and modulation type to transmit in up channel.Yet the actual bandwidth quantity that cable uses may be limit by the software control modulator-demodulator.As mentioned above, the business user can be configured to use 2Mbps on up direction, and the resident is limited to use 1Mbps.But, support commercial and resident's cable modem can run on the highest system's speed, for example 10Mbps.The priority of packet does not influence the chip rate and the modem type of configuration separately.
When cable modem 105 or 107 powers on, set up the connection of playing headend equipment 101 through hybrid fiber/coaxial circuit 103.This connects use Internet protocol (IP), when receiving that with convenient headend equipment 101 form from the Internet and World Wide Web (being commonly called external network 114) is the data of IP, these data can be sent to cable modem 105 or 106 on down direction.During the cable modem start-up course, modulator-demodulator obtains IP address, other operational factor relevant with IP and the server address of modem configuration files from Dynamic Host Configuration Protocol server (DHCP).On network, have many such Dynamic Host Configuration Protocol server to use, and cable modem 105 or 107 is simply to all Dynamic Host Configuration Protocol server broadcasting.Any Dynamic Host Configuration Protocol server can the return broadcast request and is submitted necessary information.Configuration file comprises various modem configuration parameters, such as the descending of access control information and up channel flow distribution, security configuration information and trivial file transfer protocol server, can download the modulator-demodulator operating software from this server.
The all grouping of network of cable system as shown in Figure 1 switching networks.Typically run on best (best-effort) service and transmit the basis.Unfortunately, the Internet protocol that has a transfer mode of time best connection can not guarantee that grouping is with in order, grouping is transmitted or guaranteed to transmit to mode timely.All business all have equal priority, and the equal chance that transmits in timely mode is arranged.When network congestion, all business also all have the equal chance that is delayed or withdraws from.Use in the application program of networks in many classes, the mission critical applications program that is connected with World Wide Web, online key business application program are arranged, based on multimedia application program (for example desktop conference and based on network training) and voice Internet protocol.Some web application maybe can be bandwidth and delay-sensitive, therefore requires unique grade of service on network.Some application programs need be delivered to receiving station in real time, and other can be stood certain delay.For using real-time application, for example voice IP or video conference, use Internet protocol, must guarantee to comprise that bandwidth is waited for and the acceptable grade of service of shake requirement, and further satisfy the grade of service in the mode that allows real time business and traditional data business on network, to coexist.Use grade of service notion to allow the network operator to guarantee that mission critical and real-time application business are not subjected to the influence of the application program of other occupied bandwidth, make time crucial application to use network simultaneously in the rational and effective mode.In order to reach this purpose, the network classes of service strategy is adjusted Internet resources and network user's object.Do not have these class of service parameters, Internet resources will be cost to sacrifice prior application program, are exhausted by non-essential application program very soon.The realization of service features grade allows network equipment identification and transmits higher priority business in predictable mode.When network congestion took place, grade of service mechanism reduced, or postponed the low business of priority to allow to transmit the high business of priority.
Therefore, in the packet switching cable modem system, there are a kind of needs: set up grade of service scheme, and its mechanism of developing operation, thereby increase the possibility that the high upstream of priority can arrive its destination in mode timely.

Embodiment
Before describing in detail, should be noted that the present invention at first belongs to the combination of step and device according to the adhoc approach and device that is used for downloading the unique configuration file (with its recent release) that is used for cable modem of the present invention.Therefore, the hardware of described conventional element and method step in the accompanying drawings, only show the specific detail relevant with the present invention, of the present inventionly openly thicken to make without detail of construction, these detail of construction that have in the advantage of this explanation are conspicuous for those of ordinary skills.
The DOCSIS1.0 agreement allows to a plurality of service flow of cable modem configuration such as cable modem 105 and 106, to be used for transmitting data at up direction.Yet cable operated person (cable operator) can not utilize this feature, because except main service flow (primary service flow), there is not mechanism that master data is categorized on the service flow in the industry.Therefore, all data all flow on Your Majesty's row service flow.The DOCSIS1.1 standard comprises the grader feature that can activate by configuration setting, sends some grouping with the indication cable modem on service specified stream and sends.For example, grader can be configured to all packets of voice are placed on No. 2 service flow, and all other packets send through main service flow.
The instruction according to the present invention, main service flow are divided into many a plurality of son streams.In a plurality of son streams each has all been distributed a grade of service, and this grade is relative grade or priority scheme, is used for determining that the data queued with on that son stream sends to headend equipment 101 from cable modem 105 and 106.The grade higher data sent before junior data.For example, the voice IP phone is called out to be close to and is sent in real time to avoid delay and the interruption in the communication process.Have been found that greater than about 300 milliseconds delay and be difficult to usually be stood by the caller.Therefore, represent the data of voice Internet protocol can be assigned to the service of higher priority.Otherwise lteral data is received the lower priority assignment of the grade of service.
In configuration file, set the service flow parameters (for example sending priority) that is used for given modulator-demodulator.The parameter of son stream derives from service flow parameters, and this will set forth hereinafter.
In one embodiment of the invention, the up son stream of packet is carried in the management of token store section (token bucket) method, can send from cable modem 105 and 106 according to the service priority that it was distributed to guarantee grouping.Each token store section has three parts: burst length, Mean Speed, and the time interval.Middle (on average) speed has stipulated how many data time per unit (defined by the time interval) can send.Burst length (calculating with bit) has been stipulated generation network scheduling conflicting data quantity that can send, unlikely in a pulse train.The algorithm that has the example token memory paragraph of 5Mb token store section burst length has the intermediate bit speed of 1Mbps and one second the time interval.Memory paragraph has the capacity that is 5 megabits to the maximum.When memory paragraph becomes full (, comprised 5,000,000 tokens (worth oftoken)), then can not add token again.
Each token is represented a permission, allows cable modem that some bit is sent to headend equipment 101.In order to send grouping, cable modem is deleted a plurality of tokens that equal to represent block length quantity from memory paragraph.If there are not enough tokens to send grouping in memory paragraph, or packet awaits has enough tokens up to memory paragraph, or abandons grouping simply.Therefore, at any time, the pulse train of the maximum that cable modem can send in network or grouping are in general proportional with the memory paragraph capacity.
The further instruction according to the present invention is controlled by a plurality of token store sections from the grouping transmission of cable modem 105 and 106, and wherein, each token store section is related with the specific grade of service that is used for each cable modem (or son stream).Token from the main flow memory paragraph is distributed in a plurality of son stream memory paragraphs.As mentioned above, token is replenished in the primary storage section periodically.Each son stream memory paragraph is replenished from main token store section.In fact, there are many kinds to be used for replenishing the algorithm of son stream memory paragraph.For example, the primary storage section can be controlled so as to and be given percentage that has received token of each son stream memory paragraph distribution.For example, the son of limit priority stream memory paragraph (memory paragraph one) can be received 50% of primary storage section token in a given interval.Lowest priority stream memory paragraph (memory paragraph three) can be received 15% of primary storage section token in the identical time interval.At last, the memory paragraph of middle priority (memory paragraph two) can be received 35% of primary storage section token in the given time interval.Alternatively, when token enters in the primary storage section, they at first can be pointed to memory paragraph one (limit priority stream memory paragraph) and become full up to it.This has guaranteed that the limit priority meeting in group has the possibility of higher reception token, thereby has the higher priority that is sent out.So the directed memory paragraph two of the token of receiving afterwards becomes full up to its, (suppose memory paragraph one keep full) is last, if when two other memory paragraph is all expired, and the directed memory paragraph three of the token of arrival.As what those skilled in the art understood, can use some kinds of technology to control and be used for primary storage section and a plurality of sub additional process that flows memory paragraphs.
The algorithm that is used for additional primary storage section and a plurality of son stream memory paragraphs can be the hard code (hard-coded) of cable modem 105 and 106.Alternatively, by the startup stage with the TLV parameter downloads of manufacturer regulation to cable modem 105 and 106, also this algorithm can be set in configuration file.Use configuration file as controlling mechanism, allow the cable system operator to change and be used for the additional algorithm that a plurality of sons flow.The cable system operator also can manage each cable modem 105 and 106 by the network management-application software of utilization and operation under Simple Network Management Protocol (SNMP).Thereby the network object that SNMP allows network manager to change in the network equipment changes network parameter.For example, can replenish process by revise memory paragraph in real time based on the SNMP structure.
In one embodiment, by being included in the information in the packets headers, be one in each packet allocated substreams.For example, it is the IP data that packets headers is discerned this grouping, LLC data, or TCP/UDP data.Based on data type, packet is assigned with suitable priority stream, and the relation between data type and the priority stream sets at configuration file or the hard code that writes modulator-demodulator.Or choosing ground, for the recognition data type, modulator-demodulator can be checked the data file that is used for unique data signature (data signature).The VOIP data have so unique signature.In another embodiment, modulator-demodulator can the recognition data type and is come allocated substreams by the software application that is embedded in cable modem that grouping is sent in inspection.For example, network-management application produces simple NMP grouping.Typically, the SNMP meeting in group is assigned to the priority that is higher than packet.
Replace cable modem to check head with allocated substreams, the application software that produces grouping can allocated substreams, and information is provided as parameter.In another example, modulator-demodulator can comprise the VOIP software application, and this application program will be carried out digitlization from the audible sound of phone, and they are divided into groups.In this example, do not need to check that grouping is to determine their priority, because the modulator-demodulator operating software can determine to divide into groups to come from the software application that speech data is operated.Typically, these groupings will be assigned to high priority stream.
Fig. 3 illustrates the software flow pattern of explanation the present invention instruction.Modulator- demodulator 105 or 106 powers at step 180 place, and in step 182 place download configuration file.In embodiments of the present invention, wherein discern the details that a plurality of son streams and memory paragraph replenish algorithm in the configuration file, this information is to derive from configuration file, and is provided for the modulator-demodulator operating software to be used to control the process of replenishing and sub-flow distribution.In step 186, check that the grouping that is ready to send is to determine the relative grade of service.Set forth as top other embodiment, the grade of service can be by checking that other technology beyond the head is determined.Under any circumstance, in case the grade of service that is used to divide into groups is determined, process moves to step 188, at this inspection son stream (or grade of service) memory paragraph with packet associated.If there are enough tokens to use in the memory paragraph, process moves to 192 from deciding step 190 so, distributes to grouping at this token with appropriate quantity.In step 194, send grouping.So process turns back to step 186 to check the next one grouping in the formation.If do not have the token of sufficient amount to use in deciding step 190, just can not send grouping, and it is stayed in the formation.Process turns back to step 186 from deciding step 190 and is used to check next grouping of having lined up.Replenished when the son stream token store section relevant, just sent grouping with the grouping that postpones.Although Fig. 3 flow process is not shown, as top elaboration, additional process is put into token each son stream memory paragraph periodically.In one embodiment, additional process is carried out as follows.Make that R/T is the medium rates of algorithm, wherein R calculate with bit and T to calculate second.Then there is the token of R bit to be added in the memory paragraph second at every T.If for example R=1 megabit, and T=1 second, per second has 1,000,000 token to be added in the memory paragraph so.Therefore medium rates is 1Mbps.
As mentioned above, the cable system operator can be by sending the operation that network management control information (use snmp protocol) is revised sub-flow distribution process to cable modem 105 and 06.Any this management information can be interrupted the flow process of Fig. 3.
Although with reference to preferred embodiment the present invention is set forth, those of ordinary skill in the art should be appreciated that and can carry out the equivalence replacement and not deviate from scope of the present invention the key element that the present invention carries out in different changes and the invention.In addition, under the situation that does not deviate from base region, the instruction of the present invention of can making amendment is to adapt to specific application.Therefore, the present invention should not be only limited to conduct and be used to attempt to realize the disclosed certain embodiments of optimal mode of the present invention, and should comprise that all fall into the embodiment of claims scope.
