Need to prove that in cluster, may hinder for some reason and carry out active and standby switching with equipment as Standby as the equipment of Master, at this situation, then former equipment as Standby can be carried out according to step 301 after newly switching to Master.
Here, available stack member link refers to pile up in the link the not Member Link of DOWN.
Be example with as shown in Figure 1 cluster, in cluster shown in Figure 1, only comprise following two equipment: equipment 1 and equipment 2, wherein, connect by piling up link between equipment 1 and the equipment 2, equipment 1 is Master, equipment 2 is Standby, then based on step 302, equipment 1 as Master belongs to the available stack member link that piles up link that is connected to equipment 2 from equipment 1 every setting collection cycle collecting device 1 this locality in cluster, such as the link a that is connected to equipment 2 among Fig. 1 from equipment 1, b, c, d outgoing direction utilance, simultaneously, also collecting device 2 this locality belong to the available stack member link that piles up link that is connected to equipment 1 from equipment 2, such as the link a that is connected to equipment 1 among Fig. 1 from equipment 2, b, c, the outgoing direction utilance of d.
Be example with as shown in Figure 4 cluster, in cluster shown in Figure 4, comprise following three equipment: equipment 1, equipment 2, equipment 3, wherein, equipment 1 is Master, equipment 2, equipment 3 are Standby, connect by piling up link between equipment 1, the equipment 2, connect by piling up link between equipment 2, the equipment 3; Then based on step 302, collect equipment 1 this locality in the cluster and belong to the available stack member link that piles up link that is connected to equipment 2 from equipment 1 and be connected to the link a1 of equipment 2 from equipment 1 such as Fig. 4 every setting the collection cycle as the equipment 1 of Master, b1, c1, d1 outgoing direction utilance, collecting device 2 this locality belong to from equipment 2 and are connected to the available stack member link that piles up link of equipment 1 such as the link a1 that is connected to equipment 1 Fig. 4 from equipment 2, b1, c1, d1 outgoing direction utilance, collecting device 2 this locality belong to from equipment 2 and are connected to the available stack member link that piles up link of equipment 3 such as the link a2 that is connected to equipment 3 Fig. 4 from equipment 2, b2, c2, d2 outgoing direction utilance, and collecting device 3 this locality belong to from equipment 3 and are connected to the available stack member link that piles up link of equipment 2 such as the link a2 that is connected to equipment 2 Fig. 4 from equipment 3, b2, c2, d2 outgoing direction utilance.The present invention is example with Fig. 1, cluster shown in Figure 4 only, and the cluster principle of other structures is similar, gives unnecessary details no longer one by one here.
From step 302 as can be seen, it is identical that Master collects cycle of available polymerization Member Link outgoing direction utilance in the cycle that Master collects available stack member link outgoing direction utilance in the step 302 and the step 301, in case this can guarantee to find the unbalance link that piles up that in time utilizes in the cluster between the equipment of aggregated links, specifically state step 304 as follows, wouldn't give unnecessary details here.
As one embodiment of the invention, among the present invention, Master collects the outgoing direction utilance of the local available polymerization Member Link of each equipment in the described cluster and the outgoing direction utilance of available stack member link can realize by the software design.Wherein, when specific implementation, need that each equipment starts a timer such as 1 second timer in the described cluster in this locality, with the set time such as 1 second being data traffic on local each the available polymerization Member Link of interval stats and local each available stack member link.
Based on this, in the above-mentioned steps 301, the outgoing direction utilance that Master collects the local available polymerization Member Link of each equipment in the described cluster every the setting collection cycle is specially:
When Master sets the collection cycle (if this cycle is that time point t1 is to a period of time between the time point t2) in current arrival, the data traffic that the local available polymerization Member Link of this each equipment is transmitted when each equipment acquisition time point t1 from described cluster and t2;
Master according to the outgoing direction utilance that following formula 1 calculates the local available polymerization Member Link of each equipment in the described cluster is:
V1=(U12–U11)/(L1×(t2–t1))。(formula 1)
Wherein, V1 be in the described cluster collected of Master the local arbitrary available polymerization Member Link of an equipment (for ease of describing, here be that example is described with available polymerization Member Link 1) the outgoing direction utilance, the data traffic via this available polymerization Member Link 1 forwarding of U12 for when time point t2, adding up, the data traffic via this available polymerization Member Link 1 forwarding of U11 for adding up when time point t1, L1 is the flow bandwidth of available polymerization Member Link 1 scheduled justice.
Equally, in the above-mentioned steps 302, the outgoing direction utilance that Master collects the local available stack member link of each equipment in the described cluster every the setting collection cycle is specially:
When Master sets the collection cycle (if this cycle is that time point t1 is to a period of time between the time point t2) in current arrival, the data traffic that the local available stack member link of this each equipment is transmitted when each equipment acquisition time point t1 from described cluster and t2;
The outgoing direction utilance that Master collects the local available stack member link of each equipment in the described cluster according to following formula 2 is:
V2=(U22–U21)/(L2×(t2–t1))。(formula 2)
Wherein, V2 be in the described cluster collected of Master the local arbitrary available stack member link of an equipment (for ease of describing, here be that example is described with available stack member link 1) the outgoing direction utilance, the data traffic via this available stack member link 1 forwarding of U22 for when time point t2, adding up, the data traffic via this available stack member link 1 forwarding of U21 for adding up when time point t1, L2 is that available stack member link 1 is by predefined flow bandwidth.
。
Below simply describe Master and how to have collected the outgoing direction utilance of the local available polymerization Member Link of each equipment in the described cluster and the outgoing direction utilance of available stack member link.Need to prove, top description just Master is collected the outgoing direction utilance of the local available polymerization Member Link of each equipment in the described cluster and a kind of of outgoing direction utilance of available stack member link gives an example, and non-limiting the present invention, under the prerequisite of not improving inventive concept, also can adopt other modes to realize that Master collects the outgoing direction utilance of the local available polymerization Member Link of each equipment in the described cluster and the outgoing direction utilance of available stack member link.
Here, the unbalance condition of the aggregated links of setting can be according to the actual conditions setting.
As a preferred embodiment of the present invention, the unbalance condition of the aggregated links of setting can comprise following 4 conditions:
Condition 1: exist in the cluster and satisfy the equipment of setting fully loaded transportation condition.Here, the outgoing direction utilance that the equipment of setting fully loaded transportation condition refers to local each available polymerization Member Link is all more than or equal to the equipment of the polymerization Member Link outgoing direction utilance upper limit threshold of setting, to satisfy the equipment of setting fully loaded transportation condition in the present invention and be called for short heave-load device, below all be described with heave-load device.
Condition 2: at least one equipment adjacent with described heave-load device satisfies the underloading condition of setting in the cluster.Here, equipment that satisfy to set the underloading condition refer to local each available polymerization Member Link the outgoing direction utilance all smaller or equal to the equipment of the polymerization Member Link outgoing direction utilance lower threshold of setting.In the present invention, the polymerization Member Link outgoing direction utilance upper limit threshold of setting is greater than the polymerization Member Link outgoing direction utilance lower threshold of setting, Member Link outgoing direction utilance upper limit threshold such as setting is 90%, and the Member Link outgoing direction utilance lower threshold of setting is 50%.Need to prove, will satisfy the equipment of setting the underloading condition in the present invention and be called for short underloading equipment, below all be described with underloading equipment.
Condition 3: the difference of the available polymerization member number of links of the available polymerization member number of links of this locality of heave-load device described in the cluster and adjacent underloading equipment this locality satisfies sets deviation threshold;
Condition 4: the outgoing direction utilance from least one available stack member link between the described heave-load device underloading equipment that extremely described heave-load device is adjacent in the cluster satisfies the available stack member link outgoing direction utilance threshold value of setting.
More than the unbalance condition of aggregated links is described.Need to prove that in the present invention, above-mentioned restriction at the unbalance condition of aggregated links only is a kind of giving an example, is not that the present invention also can only comprise condition 1, condition 2, condition 4 when realizing for restriction the present invention.Perhaps other ways of realization are described here no longer one by one for example.
Also need to prove, in the present invention, when the checking result of step 303 for not the time, as one embodiment of the present of invention, the present invention can not carry out any operation, still carries out the forwarding of data flow by the link-local priority principle of equipment in the prior art.
Among the present invention, at each equipment in the cluster, all can wherein, record the available polymerization Member Link of this equipment this locality in this aggregated links table at aggregated links table of the local configuration of this equipment, based on this, this step 304 is specially:
At least one available stack member link that Master selects described heave-load device to be connected to described underloading equipment is added to the aggregated links table of described heave-load device this locality, so that heave-load device when receiving the data flow that need transmit by aggregated links, utilizes in the local aggregated links table all link equilibriums to share this data flow.
As a preferred embodiment of the present invention, Master can select in the described cluster from heave-load device this locality availablely to pile up the aggregated links table that link adds described heave-load device this locality at least one of the adjacent underloading equipment of this heave-load device by following steps:
Step 1, Master identifies the available stack member link that meets the following conditions from described heave-load device is connected to all available stack member links of adjacent underloading equipment: the outgoing direction utilance satisfies the available link outgoing direction utilance threshold value of setting of piling up;
Step 2, Master is M+X and L relatively, and wherein, M is the quantity of the local available polymerization Member Link of described heave-load device, the quantity of the X available stack member link that to be Master identify in step 1, L is the quantity of maximum available links of setting at heave-load device in advance;
If M+X＜=L, all available stack member links of selecting step 1 to identify add the aggregated links table of described heave-load device this locality;
If M+X〉L, the available stack member link of Y bar adds the aggregated links table of described heave-load device this locality before selecting from the available stack member link that step 1 identifies, and described Y satisfies M+Y＜=L.
By above step 1 and step 2 as can be seen, among the present invention, in case heave-load device is arranged, the forwarding that then can select at least one available stack member link from heave-load device to adjacent underloading equipment to share data flow with the available polymerization Member Link equilibrium of described heave-load device this locality in the cluster.Here, at least one available stack member link from heave-load device to adjacent underloading equipment just temporarily with the forwarding of the available polymerization Member Link load balancing data flow of heave-load device this locality, does not influence the flow forwarding of this stack member link itself.And, based on step 1 and step 2, can guarantee heave-load device at least one available stack member link of adjacent underloading equipment when transmitting with the available polymerization Member Link load balancing data flow of heave-load device this locality temporarily, can not occur transmitting mutually congested phenomenon with the original flow of this available stack member.
So far, finish flow process shown in Figure 3.Be that example is described flow process shown in Figure 3 with cluster shown in Figure 1 below:
As shown in Figure 1, in cluster shown in Figure 1, only comprise following two equipment: equipment 1 and equipment 2, wherein, connect by piling up link between equipment 1 and the equipment 2, equipment 1 is local to be existed and belongs to from equipment 1 to equipment 4 available stack member links that pile up link of 2, and these 4 available stack member links are 10 by predefined flow bandwidth.In the available polymerization Member Link of aggregated links two links to be arranged be link 1 and link 2DOWN if belong to as equipment 1 this locality of Master, and being link 3 and link 4, other two links can use, and these two available links 3 and link 4 are 10M by predefined flow bandwidth, then receive to be 40M by the data flow of aggregated links forwarding when equipment 1, two available polymerization Member Links that will belong to aggregated links by this locality according to existing mode equipment 1 are the data flow that link 3 and link 4 are shared 20M respectively, and because link 3 and link 4 all can only carry the flow of 10M at most, this link congestion shown in Figure 2 will occur, that is: the data flow of this 40M will cause that link 3 and link 4 take place congested.
And if adopt the present invention, be heave-load device at equipment 1 then, and with equipment 1 by piling up link and be connected and as the equipment 2 of Standby during for underloading equipment, selecting from equipment 1 to equipment two available stack member links of 2 as the equipment 1 of Master according to above-mentioned steps 304 is link a, link b is added to the aggregated links table of equipment 1 this locality, so, when equipment 1 is received the data flow of the 40M that need transmit by aggregated links, equipment 1 will be link 3 and link 4 by two available Member Links that belong to aggregated links of local aggregated links table record, and from equipment 1 to equipment 2 available stack member links of 2 are link a, link b shares the data flow of transmitting this 40M together, specifically as shown in Figure 5, this congested phenomenon of Member Link that equipment causes based on local first principle forwarding data flow in the cluster obviously can not occur when part Member Link DOWN.
