Information Rate, peak bandwidth) and bandwidth scheduling ratio, so as to reach the isolation of different levels customer traffic, while again
It can guarantee that the distribution order of different priorities message under same client's level.For example walk same tunnel in 2 of MPLS network side
Road PW (Pseudo Wire, pseudo-wire) layer enables HQOS respectively, and mounts 8 priority under each PW scheduling node simultaneously
Queue.According to certain scheduling strategy between such 2 PW, such as WFQ (weighted-fair) algorithm, DWRR (random weighting poll) is calculated
Method etc. is scheduled.Inside the scheduling node of each operation level, it can be mapped to according to the different priorities field of message
Different priority queries realizes the forwarding of the message of different priorities.
The shortcomings that HQOS is solved in DiffServ models, and business can not isolate, while and can ensures same scheduling level
The forwarding of lower business prior message.But the scheduling method between different dispatch layers time is relatively more fixed, WFQ (weighted-fair) is calculated
Method, DWRR (random weighting poll) and Strict Priority (strict priority) are to cannot be distinguished by business between scheduling node
Priority.And with the requirement more and more higher of network scenarios, the client traffic of same paths carrying nor one one-tenth not
Become, the scheduling strategy for simply configuring different scheduling levels can not meet demand of the client for bandwidth of complexity.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1 is the scheduling node illustraton of model after configuration HQOS of the prior art.The client of PW1 carryings is private line service.
The client of PW2 carryings is VOIP business.LSP (Label Switched Path, label switched path) is because of the next-hop of network
Convergent point, it is desirable to the exit port configuration 300Mbps of present networks equipment speed limit.Simultaneously PW1 configuration 100Mbps CIR and
300Mbps PIR, PW2 client also configure 100Mbps CIR and 300Mbps PIR.PW1 and PW2 configurations WFQ (is added simultaneously
Weigh Fair Queue) ratio is dispatched as 1:1.So in actual use, a certain moment, PW1 user are now surfing the Net,
For PW2 client in voice call, the actual flow of two business is all 200M.Actual flow is the 100Mbps+ that PW1 is CIR
Scheduling bandwidth 50Mbps, it is as a result 150Mbps.PW2 is CIR 100Mbps+ scheduling bandwidths 50Mbps.Actual flow is equal,
Do not ensure that the speech business of high priority is preferential.Assuming that now, the flow of client changes, as PW1 client now
Video conference is initiated, the band width configuration of the network equipment does not still change.Also the smoothness of video conference can not be ensured.
For the above situation, the embodiment of the present invention provides a kind of MPLS network bandwidth allocation methods based on HQoS, such as Fig. 2
It is shown, specifically comprise the following steps：
Step 1, obtain scheduling level distributes bandwidth；Wherein, the bandwidth of distributing is according in the scheduling level
The guarantee bandwidth and peak bandwidth that each scheduling node is pre-configured with obtain.
In this step, the same scheduling level of MPLS network, each scheduling node have been pre-configured with CIR and PIR.Such as figure
Shown in 1, the CIR that PW1 and PW2 are respectively configured is 100Mbps, PIR 300Mbps.Mounted under each PW scheduling node excellent
First level queue, the forwarding of message is carried out according to the preferred field carried in message.In the scheduling level, PIR 300Mbps.
That is, removing outside PW1 and PW2 CIR, whole level of dispatching can be distributed with a width of PIR- (CIRPW1+CIRPW1)=
100Mbps.The present invention can distribute the allocation proportion value of bandwidth according to the actually required Bandwidth Dynamic adjustment of each business.
Step 2, the packet loss speed that each scheduling node sends message is obtained.
In this step, it is necessary to obtain the packet loss speed that each scheduling node sends message.When packet loss speed refers to unit
The message number of interior discarding.Specifically, when obtaining packet loss speed, it is necessary to count actual packet loss by the exchange chip of equipment
Speed.The exchange chip counts the message number of scheduling node transmitting terminal and receiving terminal respectively within the unit interval.And receiving terminal and
The difference of the message number of processing is packet loss speed in the transmitting terminal unit interval.
Step 3, from that can distribute in bandwidth it is each scheduling node point according to packet loss speed according to the height of service priority
With required weighting bandwidth, so that each scheduling node is based on the bandwidth and progress business processing for ensureing bandwidth with weighting bandwidth.
In this step, according to the packet loss speed of each scheduling node, saved according to the height of priority level for each scheduling
Point additional allocation on the basis of bandwidth is ensured weights bandwidth, so as to ensure that it is high-quality that the high scheduling node of priority level can have
The network service of amount.
Specifically, when being scheduling node weights assigned bandwidth according to priority level height, specifically comprise the following steps：
Bandwidth can be distributed by obtaining the residue after upper priority scheduling node distribution；
Judge packet loss speed and the remaining size that can distribute bandwidth：When more than or equal to when, then can distribute residue to band
It is wide all to distribute to the scheduling node；When less than when, then be scheduling node distribution packet loss speed weighting bandwidth.
Wherein, packet loss speed can distribute bandwidth more than the residue after upper priority scheduling node distribution, and residue can distribute
Bandwidth can not meet the required actual speed rate of transmitting message.In that case, it is necessary to which upper priority scheduling node is divided
Residue after matching somebody with somebody can distribute bandwidth and all distribute to the scheduling node, it is ensured that the scheduling node can be assigned to the weighting band of maximum
Width, to reduce packet loss speed.And in the case of packet loss speed is less than and can distribute bandwidth, then explanation can distribute bandwidth except can be with
Meet outside the bandwidth demand of scheduling node, can also be that the scheduling node of next priority continues weights assigned bandwidth.And for
After the scheduling node of packet loss distributes weighting bandwidth, if also remaining distribute bandwidth, no longer it is allocated, the present invention is only
The actual bandwidth of the satisfaction of each scheduling node need to be ensured or be assigned to assignable maximum bandwidth.
For example, as shown in figure 3, using the band width configuration result after the present invention.PW1 carries business of networking in Fig. 3,
When PW2 carries VOIP business, PW2 priority is higher than PW1 priority.The packet loss speed of speech business is 100Mbps, its etc.
In bandwidth 100Mbps can be distributed, then directly by PW2 band width configuration be CIR (100Mbps)+weighting bandwidth (100Mbps)=
200Mbps, PIR 300Mbps.So within this time, it is ensured that the preferential forwarding of VOIP speech businesses, and PW1 is obtained
Business of networking can only have 100Mbps guarantee bandwidth.
If PW2 packet loss speed is 50Mbps, it, which is less than, can distribute bandwidth 100Mbps, then directly by PW2 band
Width is configured to CIR (100Mbps)+weighting bandwidth (50Mbps)=150Mbps.And if PW1 carry business of networking without packet loss when,
Need not distribute it is remaining distribute bandwidth (50Mbps), if having if packet loss and packet loss speed is less than 50Mbps, distributed for PW1
Corresponding weighting bandwidth；If if packet loss speed is more than or equal to 50Mbps, 50Mbps weighting band is distributed for PW1
It is wide.
Further, after it can distribute bandwidth allocation to each scheduling node, each scheduling node distribution need to be recorded
Bandwidth is weighted, when being changed for follow-up scheduling node priority, the weighting bandwidth to each scheduling node is adjusted, tool
Body includes as follows：
When the priority of some scheduling nodes in each scheduling node changes, and each scheduling node after changing
When priority level is different, check whether that residue can distribute band according to the weighting bandwidth that each scheduling node of record distributes
It is wide；
It is sequentially allocated if so, then residue can be distributed to bandwidth according to the height of priority to each scheduling node, works as residue
When can distribute bandwidth and being unsatisfactory for weighting bandwidth needed for scheduling node, then from the weighting bandwidth point of the low scheduling node distribution of priority
The scheduling node of dispensing high priority.
If nothing, directly according to the incremental order of priority, successively by the weighting bandwidth point of the low scheduling node of priority
It is assigned to the high scheduling node of priority.
For example, as shown in figure 4, in Fig. 3 PW1 business change video conference is changed into from business of networking, and PW2 continues
Carry VOIP business.Because video conference priority ratio VOIP business is higher, then the video traffic packet loss of higher priority is counted on,
And packet loss speed 60Mbps.So PW1 needs to increase 60Mbps weighting bandwidth.But it is 160Mbps that PW1, which matches somebody with somebody the CIR postponed,.
Because the PW1 weighting recorded before is with a width of 50Mbps, it is therefore desirable to which the 10Mbps in PW2 is distributed into PW1.Such PW1
The a width of CIR of video traffic band (100Mbps) weighting bandwidth (60Mbps)=160Mbps.PW2 VOIP service bandwidths are CIR
(100Mbps)+weighting bandwidth (40Mbps)=140Mbps.It so both ensure that the video traffic of high priority preferentially forwarded, together
When ensure that the smoothness of video conference with it is clear, improve the network service quality of high priority.
Understood based on above-mentioned, it is not same to all scheduling nodes when priority changes in the embodiment of the present invention
When be adjusted, but according to the weighting bandwidth of record first by the weighting bandwidth allocation of the low scheduling node of priority to priority
High scheduling node, it so directly can preferentially meet the bandwidth demand of the high scheduling node of rank, without re-starting point
Match somebody with somebody, effectively save amount of calculation, while improve the efficiency of scheduling, lift the network service experience of user.
Further, when the priority of each scheduling node changes, and priority is identical after change, then according to pre-
The bandwidth scheduling ratio first configured, bandwidth is distributed based on what guarantee bandwidth and peak bandwidth obtained, for each scheduling node point
With weighting bandwidth.For example, if the weighting bandwidth that PW1 has been configured before as PW2 message priority, should deleting, is incited somebody to action
Bandwidth scheduling ratios (such as 1 of the bandwidth 100Mbps according to being pre-configured with can be distributed:1) forwarded.
It is above-mentioned to have been carried out using two scheduling nodes in a scheduling level for example, when enabling multistage HQOS, it is complete
It can be adjusted entirely in the dynamic at all levels that all enables, weighting bandwidth interface is up set layer by layer.For more complicated multi-stage scheduling
Scene implementation is similar with above embodiment, is no longer further described.Understood based on above-mentioned, if higher priority
Signaling and protocol congestion packet loss occur for scheduling node, and the present invention can be ensured by adjusting the distribution bandwidth of corresponding scheduling level
The quality of scheduling node forwarding, MPLS network is efficiently solved in HQOS with postponing, business is preferential between cannot be distinguished by scheduling node
The problem of level.The present invention is according to different customer traffics, and dynamic adjusting bandwidth realizes the isolation of bandwidth between different business, again
The preferential forwarding of high-priority traffic between different business is can guarantee that, to better meet the quality of service under complex scene.
