Description
Technical field
The present invention relates to data processing field, particularly relate to data distributing method and the device of the binding of a kind of multilink.
Background technology
FTTS/B (Fiber to The Building, Fiber-To-The-Building/Fiber-To-The-Street, fiber-to-the-curb) VDSL2 (Second Generation Very High Speed Digital Subscriber Line both can be provided, second high-speed digital user wire) access capability, G.9701 FAST (Fast Access toSubscriber Terminals, express user terminal) access capability also can be provided; When certain user need open G.9701FAST business time, it is directly connected on FTTS/B equipment from original FTTC (Fiber-To-The-Curb, Fiber To The Curb); ADSL (Asymmetric Digital Subscriber Line can be there is inside a bundle line simultaneously, ADSL (Asymmetric Digital Subscriber Line)), VDSL2, business G.9701FAST, in order to reduce crosstalk and support vector (vectoring) function under often kind of line mode, need the mode adopting frequency division multiplexing; 0MHz ~ 2.2MHz is used as ADSL, 2.2MHz ~ 17MHz and is used as G.9701 FAST as VDSL2,23MHz ~ 106MHz; VDSL2 can carry the flow of the highest 120Mbps, and G.9701 FAST can carry the flow of the highest 1Gbps;
In order to make full use of frequency spectrum, when certain user uses G.9701 FAST access, simultaneously also can carry data traffic in the frequency range of VDSL2, message carries out load sharing on G.9701 FAST and VDSL2; Message to be distributed to G.9701 on FAST and VDSL2 path in CPE (Customer Premise Equipment, customer premises equipment, CPE/ustomer premises access equipment) side by up direction, and Business Stream merges by FTTS/B; Message is distributed to G.9701 on FAST and VDSL2 path by down direction on FTTS/B, and Business Stream merges by CPE; This technology is called hybrid G.9701 FAST (mixing express user terminal) technology.
At CO (centeroffice, central office) with CPE distance 300m distance time, G.9701 FAST can obtain the bandwidth of about 200Mbps, VDSL2 can obtain the bandwidth of about 80Mbps, by hybrid technology, user can obtain the access bandwidth of 280Mbps altogether, effectively raises the access bandwidth of user;
Between CPE and CO two communication apparatus, the physical link of many low rates or logical links are bound together, realizes the data transport functions of single high-speed link.This low rate link can be ADSL, VDSL (Very High Speed Digital Subscriber Line in practice, second high-speed digital user wire), SHDSL (Single-pair High bit rate Digital Subscriber Line, Chinese address is single to line high-speed digital subscriber line), the link of the wired or wireless technology such as FAST (Fast Access to Subscriber Terminals, express user terminal) or Ethernet.Such as the speed of every bar adsl line is 10Mbps, and so 4 adsl lines bind together, and just can realize the bandwidth for transmission rate of 40Mbps.Its advantage is by increasing number of, lines simply, just can improve the transmission bandwidth of data, and does not need communication apparatus and the Line technology of changing two ends.
Realize a bindings group for 4 links below, sketch binding and send and record principle:
Transmitter side has three messages, message is cut into the burst of multiple length-specific, and head burst (SOP) is the same with the length of health burst, and tail burst (EOP) can be the random length being not more than length-specific.Sequence number (SN) is in order numbered (12bit) message fragment, from 0, adds one successively, is added to 4095 always, and then upset is 0, and the circulation gone round and begun again, this sequence number carries in burst.Two adjacent messages, the sequence number of the tail burst of previous message and the head burst of a rear message is continuous print.Message fragment, according to the speed difference of each bar link and congestion situation, is distributed to 4 links through dispatching algorithm and gets on by transmitter side, if the speed of 4 links is the same and all do not have congested, then the burst number that every bar link is assigned with is the same.If run into certain, link appearance is congested or speed is lower, then what this link was assigned with divides sector-meeting few.
Receiver side receives the message fragment on each link and saves, the queue of the corresponding preservation burst of every bar link.Then the slicing sequence number in the queue of 4 in this bindings group is identified, and the mode that message fragment increases progressively 1 successively according to sequence number is sequenced sequence, complete sequence and the recombination function of burst.Concrete grammar is: when there being non-empty queue, if the minimum value of the slicing sequence in queue number conforms to desired value, then gets this value as current sequence number value, and the result then adding by this value is as the desired value of next SN.If the minimum value of the slicing sequence in all queues number and desired value are not inconsistent, will wait for, by the time whole queue not empty, after waiting for configurable time-out time, just can get the minimum value of sequence number as current sequence number value (no matter this value whether consistent with desired value), the result then adding by this minimum value is as the desired value of next SN.Like this, according to the sequence number that burst carries, according to from small to large put in order from receive burst queue take burst away, finally using SOP, EOP as the boundary marker of message, from message flow, distinguish message one by one, so just complete the restructuring of message.
The distribution algorithms of message fragment generally adopts DRR mode, and send burst in turn between each member belonging to bindings group, according to each link bandwidth size, distribute corresponding weight, with roomy, the weighted value of distribution more greatly.
Adopt DRR algorithm, no matter current its shortcoming be data traffic size, and all members are assigned to message fragment, and all links are all in running order, cause system to be in maximum power consumption state so always, can there is the large and problem of waste resource of power consumption.
When adopting DRR algorithm in prior art to each link assignment message fragment in bundle link, regardless of the uninterrupted of data to be transmitted, in bundle link, all links are assigned to message fragment, so each link needs the in running order transmission carrying out message fragment, even if total flow is less than the bandwidth of single link member, when data send, also can according to rule by data allocations in all link members, cause all links in system to be all in maximum power consumption state like this, so the wasting of resources to a certain degree can be caused always.
In order to solve the problem of above-mentioned prior art, as shown in Figure 1, the data distributing method that the embodiment of the present invention provides a kind of multilink to bind, many the low rate links by binding together between first communication equipment and second communication equipment realize the data transport functions of single high-speed link, first communication equipment is demand bandwidth to the traffic demand of second communication equipment sending data, then the method specifically comprises:
Step 101, when first communication equipment is by many low rate chain road direction second communication equipment sending datas binding together, determine the total bandwidth value that described many low rate links provide and demand bandwidth from the first communication equipment to second communication equipment sending data between bandwidth difference;
In embodiments of the present invention, because many low rate links by binding together between the first communication equipment and second communication equipment realize the data transport functions of single high-speed link, so when the first communication equipment is to second communication equipment sending data, spendable bandwidth is the bandwidth summation that many low speed chain circuits provide.What kind of but communication equipment is not send all data all very greatly, can take all bandwidth, so after determining the bandwidth difference between total bandwidth value and demand bandwidth, just can determine mode to transmit data by according to bandwidth is more than needed.
Step 102, if described bandwidth difference is greater than the bandwidth sum that in described many low speed chain circuits, M bar link provides, then described M bar link is adjusted to resting state, wherein, M is positive integer;
In this embodiment, resting state refers to: except testing circuit is except work, the circuit of other parts is in the operating state of power-down mode or clock " shut " mode".Equipment can save power consumption to a great extent in this condition.
Wherein, M is positive integer, and M bar link is determined from many low speed chain circuits, wherein determines that the specific implementation situation of M bar link can comprise:
A, the bandwidth only having a link to provide in many low speed chain circuits is less than bandwidth difference, then this link is adjusted to resting state;
B, the bandwidth that the N bar link in this multilink provides all is less than bandwidth difference, then from N bar link, choose M bar link, and the bandwidth sum that M bar link provides meets the following conditions:
After each link forms multiple combination in N bar link, ask the bandwidth sum of each combination; Wherein, concrete condition can be: the first, the bandwidth sum of M bar link is less than the maximum of bandwidth difference value and (M is less than or equal to N) in multiple combination; The second, the bandwidth sum of M bar link is less than bandwidth difference.
Such as: bandwidth difference is 100M, 4 links in multilink provide bandwidth to be less than bandwidth difference, and 4 links provide bandwidth respectively: 10M, 30M, 50M, 60M, be then less than the maximum of difference and should be 10+30+50; Or, select 30M and 50M two links.
Step 103, utilizes other links in described many low speed chain circuits except described M bar link to send described data.
In this embodiment, if send total bandwidth value that the traffic demand of data provides much smaller than many low rate links (after many low speed chain circuits carry these data, bandwidth is had more than needed at least roomy than the band of a link in many low speed chain circuits), then one or more link can be adjusted to resting state, being adjusted to by link after resting state can the wasting of resources of minimizing system clearly.
Further, because in the scheme that provides of the embodiment of the present invention, some links are adjusted to resting state, but in time losing message fragment, then the communication equipment receiving data can not determine be the link of resting state in transmission data, or loss of data; So need wait time-out time could determine message fragment be lose or other links transmission data, then likely can cause the time delay of transfer of data in this case.In order to solve this problem, the embodiment of the present invention provides following scheme further:
When utilizing other links in described many low speed chain circuits except described M bar link to send described data, distribute the burst of described data according to setting cycle each link enabled in described M bar link.
In this example, at set intervals, in adjusted be resting state link on distribute a burst successively, allow all members all non-NULLs, the restructuring performance of receiver side equipment receiving data can be improved.
Wherein, because maximum delay of the prior art is, the time-out time that the communication equipment receiving data can bear, so the period distances duration of described setting cycle is less than the time-out time that described second equipment can bear; Wherein, the propagation delay time difference of the link that many low rate link medium-rates connecting for described second equipment of this time-out time are the highest and the minimum link of speed.
Implement two
As shown in Figure 2, in the applied environment of reality, bandwidth required for electronic equipment data changes at any time, so when required bandwidth increases, current link transmission data is utilized to occur the situation of blocking up, then need to reactivate the link being adjusted to resting state, so the data distributing method that the embodiment of the present invention provides another multilink to bind, specifically comprise:
Step 201, when first communication equipment is by many low rate chain road direction second communication equipment sending datas binding together, determine the total bandwidth value that many low rate links provide and demand bandwidth from the first communication equipment to second communication equipment sending data between bandwidth difference;
Step 202, if described bandwidth difference is greater than the bandwidth sum that in described many low speed chain circuits, M bar link provides, then described M bar link is adjusted to resting state, wherein, M is positive integer;
Step 203, utilizes other links in described many low speed chain circuits except described M bar link to send described data.
Step 204, when detecting that the transmission cache size of arbitrary link in other links described is greater than default first threshold, enabling described M bar link and sending described data.
If a bandwidth that can meet required for electronic equipment data in many low speed chain circuits, then a link is used to carry out transfer of data;
After enabling multilink, the multilink enabled is coordinated to send message fragment, the distribution algorithms of message fragment generally adopts DRR mode, burst is sent in turn between each member belonging to bindings group, according to each link bandwidth size, distribute corresponding weight, with roomy, the weighted value of distribution more greatly.The specific implementation of receiver side reconstructed file can be:
If transmitter side has three messages, message is cut into the burst of multiple length-specific, head burst (SOP) is the same with the length of health burst, and tail burst (EOP) can be the random length being not more than length-specific.Sequence number (SN) is in order numbered (12bit) message fragment, from 0, adds one successively, is added to 4095 always, and then upset is 0, and the circulation gone round and begun again, this sequence number carries in burst.Two adjacent messages, the sequence number of the tail burst of previous message and the head burst of a rear message is continuous print.Message fragment, according to the speed difference of each bar link and congestion situation, is distributed to 4 links through dispatching algorithm and gets on by transmitter side, if the speed of 4 links is the same and all do not have congested, then the burst number that every bar link is assigned with is the same.If run into certain, link appearance is congested or speed is lower, then what this link was assigned with divides sector-meeting few.
Receiver side receives the message fragment on each link and saves, the queue of the corresponding preservation burst of every bar link.Then the slicing sequence number in the queue of 4 in this bindings group is identified, and the mode that message fragment increases progressively 1 successively according to sequence number is sequenced sequence, complete sequence and the recombination function of burst.Concrete grammar is: when there being non-empty queue, if the minimum value of the slicing sequence in queue number conforms to desired value, then gets this value as current sequence number value, and the result then adding by this value is as the desired value of next SN.If the minimum value of the slicing sequence in all queues number and desired value are not inconsistent, will wait for, by the time whole queue not empty, after waiting for configurable time-out time, just can get the minimum value of sequence number as current sequence number value (no matter this value whether consistent with desired value), the result then adding by this minimum value is as the desired value of next SN.Like this, according to the sequence number that burst carries, according to from small to large put in order from receive burst queue take burst away, finally using SOP, EOP as the boundary marker of message, from message flow, distinguish message one by one, so just complete the restructuring of message.
