As shown in Figure 1, the method for virtual private LAN flow of services speed limit of the present invention, comprising:
Step 11, receives virtual private LAN service VPLS data flow;
Step 12, judges whether described VPLS data flow will carry out overall speed limit, if so, then carries out speed limit according to overall speed limit to described VPLS data flow; Wherein, overall speed limit is the speed limit of some Virtual Switch Instance (VFI) being carried out to the overall situation, and represent the data traffic that the most multipotency of this Virtual Switch Instance (VFI) forwards, the flow exceeding this restriction all carries out discard processing;
Step 13, judges whether the described VPLS data flow after overall speed limit will carry out single Limit Rate, if so, then configures according to the individual event Limit Rate of described VPLS data flow, carries out single Limit Rate to described VPLS data flow; Wherein, single Limit Rate be in the Virtual Switch Instance (VFI) single flow or to the flow of certain processing mode to carry out speed limit;
Step 14, forwards the described VPLS data flow after single Limit Rate.
This embodiment is by first carrying out overall speed limit to the flow of VPLS data flow, carry out single Limit Rate again, solve the ineffective activity of the Limit Rate under the lower transmission means of forwarding priority, the bandwidth usage of the flow of corresponding VPLS data flow can be adjusted according to network equipment actual operation, add the mobility to VPLS Limit Rate and flexibility, improve the effective rate of utilization of bandwidth, and effectively simplify the complexity of traffic classification and handling process.
In the above-described embodiments, in step 12, can further include:
When judging that described VPLS data flow does not need to carry out overall speed limit, then the direct judgement described VPLS data flow being carried out to single Limit Rate.
In step 13, can further include:
When judging that the described VPLS data flow after overall speed limit does not need to carry out single Limit Rate, then direct described VPLS data flow after described overall speed limit to be forwarded;
If the data flow of VPLS described in step 12 does not carry out overall speed limit, and carry out in the judgement of single Limit Rate in follow-up described VPLS data flow, when also not needing to carry out single Limit Rate, then the direct described VPLS data flow to receiving in step 11 forwards.
Wherein, in above-mentioned steps 13, single Limit Rate can divide the speed limit of two kinds of ranks, the speed limit of first level transmission means and the speed limit of second level transmission means, wherein first level transmission means can be multicast or clean culture rank, and second level transmission means can be broadcast or unknown unicast rank;
Wherein, the individual event Limit Rate according to described VPLS data flow configures, and the step of described VPLS data flow being carried out to single Limit Rate can be specially:
Step 131, the individual event Limit Rate according to described VPLS data flow configures, and carries out single Limit Rate according to the VPLS data flow of the first speed limit to first level transmission means; And/or
Step 132, the individual event Limit Rate according to described VPLS data flow configures, and carries out single Limit Rate according to the VPLS data flow of the second speed limit to second level transmission means.
As mentioned above, in this step 131 and step 132, described first level transmission means is multicast mode, and second level transmission means is broadcast mode; Or described first level transmission means is mode of unicast, second level transmission means is that unknown unicast puts mode.
The flow of VPLS data flow can be roughly divided into multicast, broadcast, clean culture and unknown unicast, and broadcast can regard a kind of special circumstances of multicast as, and clean culture all belonged to unknown unicast before the MAC not acquiring opposite equip..Therefore, from the differentiation of flow, two kinds of flows can be divided into carry out speed limit unified for the flow of VPLS data flow, the single Limit Rate namely under above-mentioned overall speed limit and overall speed limit.
Multicast is that the form of one-to-many copies, and can regard the combination of multiple clean culture as, processing mode can be united; The processing mode of broadcast and unknown unicast is substantially similar.Therefore, the processing mode of data, multicast and clean culture can be processed speed limit with same processing mode forward, broadcast and unknown unicast process speed limit with same processing mode and forward.
In above-mentioned steps 131 and step 132, concrete implementation of carrying out carrying out VPLS flow speed limit forwarding according to the configuration of individual event Limit Rate comprises following several:
1) when the individual event Limit Rate configuration of described VPLS data flow only configures: when carrying out single Limit Rate according to the VPLS data flow of the first speed limit to described first level transmission means, be then that the VPLS data flow of the second speed limit to second level transmission means of the 1/N of described first speed limit carries out single Limit Rate according to value, described N be greater than 1 integer; Preferably, the value of this N is 10, and namely the second speed limit is the first speed limit 1/10th, and concrete application example can more be described in detail in following mode embodiment illustrated in fig. 3.
2) when the individual event Limit Rate of described VPLS data flow configures: carry out single Limit Rate according to the VPLS data flow of the first speed limit to described first level transmission means, when carrying out single Limit Rate according to the VPLS data flow of the second speed limit to described second level transmission means of configuration simultaneously, be then the smaller in second speed limit of 1/N of described first speed limit and the second speed limit of configuration according to value, single Limit Rate is carried out to the VPLS data flow of described second level transmission means, concrete application example can more be described in detail in following mode embodiment illustrated in fig. 3.
3) when the individual event Limit Rate configuration of described VPLS data flow only configures: when carrying out single Limit Rate according to the VPLS data flow of the second speed limit to described second level transmission means, then do not relate to the speed limit of the VPLS data flow to described first level transmission means.
4) when the individual event Limit Rate of described VPLS data flow is configured to: the VPLS data flow of described second level transmission means is provided with speed limit priority, then according to the corresponding speed limit of described speed limit priority, single Limit Rate is carried out to the VPLS data flow of described second level transmission means.

As shown in Figure 2, be above-mentioned detailed implementation method embodiment illustrated in fig. 1, the method comprises:
Steps A, configuration virtual forwarding instance (VFI) on equipment, and under its pattern, configure overall speed limit and single Limit Rate;
Step B, after port receives data flow, judges whether this port is VPLS port, if VPLS port, enters VPLS speed limit flow process;
Step C, judges whether this Virtual Switch Instance (VFI) is configured with overall speed limit, if configure overall speed limit, carries out speed limit according to overall speed limit to described VPLS data flow; Otherwise, forward step D to;
Step D, extracts object MAC and judges it is any flow, determines whether to carry out the configuration of certain individual event Limit Rate simultaneously, carries out single Limit Rate;
In this step D, first distinguish the type of configuration flow, make different speed limit process, this different speed limit process is as follows:
Step D1, configuration multicast carries out speed limit according to rule, and broadcast speed limit is 1/10th of rule simultaneously; Or configuration clean culture carries out speed limit according to rule, unknown unicast speed limit is 1/10th of rule simultaneously;
Step D2, configuration broadcast or unknown unicast speed limit, only carry out speed limit to corresponding broadcast or unknown unicast according to rule;
Step D3, configuration multicast or clean culture speed limit, configuration broadcast or unknown unicast speed limit, regularly carry out speed limit to multicast simultaneously, carries out speed limit according to rule to broadcast simultaneously; Regularly speed limit is carried out to clean culture, simultaneously according to rule to unknown unicast carry out speed limit (both get the speed limit of the speed limit of rule 1/10th and configuration minimum carry out speed limit);
User also has to be needed to carry out special speed limit to broadcast or unknown unicast in a special case, therefore, the instruction of a speed limit priority can be set, corresponding speed limit is got according to priority, or do not carry out the dependent instruction that both compare, only get broadcast or speed limit is carried out in the configuration of unknown unicast speed limit; If be now configured with the instruction or priority instruction that do not compare, carrying out speed limit or carrying out value speed limit according to priority so only according to broadcast or unknown unicast actual disposition; Otherwise, do not carry out single Limit Rate;
Step D4, carries out the forwarding of VPLS data traffic according to speed limit rule.
As shown in Figure 3, be the application of above-mentioned method for limiting speed in concrete network, shown in concrete network connection layout, PE1 and PE2 enables VPLS, and PE configures relevant VPLS speed limit configuration, and reached and carried out speed limit to VPLS, concrete steps are as follows:
Step 1) configure on PE relevant VPLS data flow Limit Rate configuration, terminal device upgrades, and can forward VPLS data flow normally;
Step 2) under VFI (Virtual Switch Instance) pattern, configure overall speed limit 100M (this VFI only allows to forward the flow of 100M);
Step 3) under VFI (Virtual Switch Instance) pattern, configure 50% (now unicast traffic speed limit is 100*50%, is 50M, and unknown unicast speed limit is 50*10% be 5M) that clean culture speed limit is overall speed limit;
Step 4) under VFI (Virtual Switch Instance) pattern, configure that unknown unicast speed limit is overall speed limit 10%, (the unknown unicast speed limit of the setting of this order is that 100M*10% is 10M, but due to step 3) in for speed limit be 5M, thus selecting less speed limit, is 5M.)
Step 5) under VFI (Virtual Switch Instance) pattern, configure a unknown unicast speed limit command prioritization weight, then directly select that unknown unicast speed limit (by step 4) configures 10%, direct speed limit is 100*10%, is 10M).
Such scheme of the present invention is compared with prior art: invention introduces the relevance to VPLS Limit Rate, corresponding Limit Rate is associated while configuring a kind of speed limit, and in multicast or clean culture speed limit, broadcast or unknown unicast speed limit simultaneous time, carry out speed limit rule to compare and the function of selecting it little, and use the function of special speed limit under special circumstances; And solve the ineffective activity of the lower broadcast of forwarding priority and unknown unicast speed limit, the bandwidth usage of corresponding discharge can be adjusted according to network equipment actual operation, add the mobility to VPLS Limit Rate and flexibility.Improve the effective rate of utilization of bandwidth.And effectively simplify the complexity of traffic classification and handling process.
