The logic interface of this identical the end node whether virtual polymerization sub-interface after the polymerization interface after website judgement is added and interpolation comprises, if judgment result is that be, virtual polymerization sub-interface after deletion is added if the determination result is NO, keeps the virtual polymerization sub-interface after adding.

Compared with prior art, the present invention has the following advantages:

By using technical scheme of the present invention, solved when realizing the Ploymerized Interface operation in the RPR system, when a node on certain annular link breaks down, cause whole annular link unavailable, affect the problem of network service, by set up the mode of corresponding virtual polymerization sub-interface according to malfunctioning node, carry out network service in minute faulty link, improve the reliability of RPR link.

In order further to set forth technological thought of the present invention, existing in conjunction with concrete application scenarios, technical scheme of the present invention is described.

Equally take as shown in Figure 1 application scenarios as example, comprise S1, S2, S3, four websites of S4 in the RPR looped network, the annular link (being previously described ring) of being connected with ring3 by ring1, ring2 between each website connects, on each website, the logic interface of the RPR node corresponding with each annular link is respectively R1, R2 and R3, setting up respectively the polymerization interface on each website is L1, wherein, L1 comprises R1, R2 and R3 simultaneously.

As shown in Figure 2, when the node of the upper ring3 of website S2 breaks down (the logic interface R3 on website S2 can't connect), increase the virtual polymerization sub-interface of an inside on the polymerization interface on S1, S3, S4.Because the processing on S1, S3, S4 is identical, below describe as an example of the processing procedure of website S1 example.

Specifically as shown in Figure 4, the schematic flow sheet for the communication means of the RPR looped network under a kind of concrete application scenarios proposed by the invention specifically comprises the following steps:

Set up virtual polymerization sub-interface in step S401, website S1.

At first, the RPR logic interface of the ring1 on website S1, ring2, the corresponding node of ring3 is R1, R2 and R3, and the polymerization interface that comprises above-mentioned three logic interfaces is L1, further increases in this step a virtual polymerization sub-interface L1.1.

The member interface of L1 is logic interface R1, logic interface R2 and logic interface R3, and the member interface of L1.1 only has logic interface R1 and the logic interface R2 of normal node place ring in website S1, does not namely comprise the logic interface R3 that is positioned at identical ring in website S1 with the malfunctioning node of website S2 in L1.1.

Be that logic interface R1, logic interface R2 add polymerization interface L1 and virtual polymerization sub-interface L1.1 simultaneously, and logic interface R3 only add L1.

The virtual polymerization sub-interface node state that to be website encircle on each website according to RPR creates and deletion automatically, creates when the node of a website on certain ring breaks down, and deletes when the fault recovery of this malfunctioning node.

Virtual polymerization sub-interface is that inner the realization used, and the user is invisible.Why be called virtual polymerization sub-interface and be exactly because this virtual polymerization sub-interface user is invisible, and have identical member interface with original polymerization interface.

To be website create according to the situation of RPR aggregation group interior nodes internal virtual polymerization sub-interface automatically, occurs under finding certain RPR ring that node hinders for some reason and create when disappearing; Deletion this virtual polymerization sub-interface when the fault recovery of the node that disappears, the node in some RPR rings disappear and are actually that corresponding logic interface cisco unity malfunction causes owing to encircling with this RPR on this RPR node.

Step S402, website S1 carry out the MAC address learning of other nodes.

When carrying out MAC address learning on website S1, needing the judgement message is which website is come, and processes accordingly according to judged result.

Come if the message of learning MAC address is slave site S3 or website S4, the outgoing interface of MAC Address is set to L1; Come if the message of learning MAC address is slave site S2, the outgoing interface of MAC Address is set to L1.1.

But when the user was shown, the outgoing interface unification was shown as L1, and namely the interior polymeric sub-interface is invisible to the user.

Concrete, website is that the SMAC address judgement message of RPR head in the basis message that receives is from which website to come.

Step S403, website S1 carry out the ARP study of other nodes.

When carrying out ARP study on website S1, needing the judgement message is which website is come, and processes accordingly according to judged result.

If the message of study ARP is that slave site S3 or website S4 come, the outgoing interface of ARP list item is set to L1; If the message of study ARP is that slave site S2 comes, the outgoing interface of ARP list item is set to L1.1.

But when the user was shown, the outgoing interface unification was shown as L1, and namely the interior polymeric interface is invisible to the user.

Concrete, website is that the SMAC address judgement message of RPR head in the basis message that receives is from which website to come.

It is pointed out that above-mentioned step S402 and step S403 do not have the differentiation of sequencing, sequence number does not affect the variation of execution sequence just for convenience of explanation.

By above-mentioned step S402 and S403, website S1 has set up the forwarding-table item of other each websites in the system.

The type of each message that step S404, website S1 identification receives.

If unicast message, execution in step S405;

If multicast message or broadcasting packet, execution in step S406.

Step S405, forward according to MAC Address list item, ARP list item.

When needing to forward two layers of unicast message or three layers of unicast message on website S1, inquire about MAC Address list item or ARP list item, select to forward from polymerization interface L1 or virtual polymerization sub-interface L1.1 according to the outgoing interface of list item.

If the outgoing interface of list item is polymerization interface L1, to describe as can be known according to above-mentioned setting, the message of this list item study is that slave site S3 or website S4 come, and therefore, can share ring1, ring2, ring3 when forwarding on polymerization interface L1.

If the outgoing interface of list item is virtual polymerization sub-interface L1.1, describe as can be known according to above-mentioned setting, the message of this list item study is that slave site S2 comes, therefore, when forwarding, only can share ring1 and ring2 on virtual polymerization sub-interface L1.1, avoid the ring3 at the corresponding logic interface R3 of malfunctioning node place, thereby, guarantee that website S2 can receive message.

Step S406, multicast, broadcasting packet only forward from virtual polymerization sub-interface.

When needing forwarding multicasting or broadcasting packet on website S1, because guaranteeing message, needs can receive by slave site S2, and therefore, multicast or broadcasting packet can only forward from virtual polymerization sub-interface L1.1, namely share on ring1 and ring2.And when forwarding from virtual polymerization sub-interface L1.1, can not forward from polymerization interface L1 again, otherwise other websites in looped network will be received 2 parts of messages.

On specific implementation, guarantee that the method that multicast, broadcast traffic only forward is on virtual polymerization sub-interface L1.1:

1) when being supported in this RPR looped network when directly forbidding the arranging of multicast, broadcast traffic on the polymerization interface, forbid on polymerization interface L1 that multicast, broadcast traffic get final product.

2) when carrying out multicast, broadcast traffic forwarding by multicast, broadcast interface list in this RPR looped network, first the logic interface in polymerization interface L1 is rejected from multicast, broadcast interface list, then the logic interface in virtual polymerization sub-interface L1.1 is added multicast, broadcast interface list.

3) if three layers of multicast because original related aggregation group is polymerization interface L1, need to be updated to virtual polymerization sub-interface L1.1 at this moment.If adopt the form of interface list, logic interface R3 (being the logic interface that differs between L1 and L1.1) rejecting is got final product.

Whether step S407, failure judgement are recovered.

If do not recover, return to step S404;

If recover, execution in step S408.

Step S408, website S1 delete virtual polymerization sub-interface.

above flow process is to describe as an example of website S1 example, because having fault equally, website S3 and website S4 do not occur, so, corresponding flow process equally as shown in Figure 4, be not repeated, but for website S2, because fault has occured the logic interface on node wherein, this logic interface can not normally carry out Business Processing again, so, polymerization interface in website S2 directly changes to the L1 of logic interface R1 and logic interface R2 composition, therefore, because the member interface in the polymerization interface itself variation has occured, therefore, adopt the quick handover mechanism of existing polymerization to get final product, need not other modifications.

And on website S1, website S3 and website S4, because aggregation group changes, therefore, if realize that quick switching need to carry out extra process.At first, the node failure that the corresponding ring3 of website S2 detected on website S1, website S3, website S4 (is the corresponding node failure of logic interface R3 on S2, this detection can be responded to fast by the RPR change in topology), immediately the outgoing interface of all MAC, ARP and multicast list is updated to virtual polymerization sub-interface L1.1.

Because virtual polymerization sub-interface L1.1 is complete ring, so flow guarantees and can pass through.If what multicast adopted is the form of interface table, logic interface R3 rejecting is got final product.

Then, trigger relearning of MAC, ARP at website S1, website S3, website S4.Relearning of MAC can realize by the MAC Address of learning under the deletion aggregation port.Relearning of ARP can ask to realize by initiate ARP on virtual polymerization sub-interface L1.1.

At last, adopt the mode of aforesaid step S402 and step S403 to relearn MAC and ARP list item, the outgoing interface of MAC and ARP is learnt respectively on virtual polymerization sub-interface L1 or L1.1 polymerization interface according to the situation of source node, guarantee flow can by and also can be on the fault ring load balancing.

When malfunctioning node recovers, it is the fault recovery of the malfunctioning node on website S2, when logic interface R3 place website occurs in ring3 again, the MAC Address list item that website S1, website S3, website S4 upward learn virtual polymerization sub-interface L1.1 and the outgoing interface of ARP list item are updated to polymerization interface L1, then delete virtual polymerization sub-interface L1.1.Multicast list upgrades outgoing interface to be polymerization interface L1 or to increase logic interface R3 as outgoing interface.

In concrete application scenarios, often there is the situation of a plurality of faults.

Wherein, when two nodes on the different ring of being positioned at of same website broke down, corresponding handling process was as follows:

As shown in Figure 5, the node of website S2 on ring2 and ring3 all breaks down, and be the same with aforementioned flow process, creates internal virtual polymerization sub-interface L1.1 on website S1, website S3, website S4, and the member interface of L1.1 only has logic interface R1.The foundation of L1.1 is actually in order to guarantee to avoid the corresponding logic interface R2 of malfunctioning node and logic interface R3, thereby, make website S1, website S3, website S4 send corresponding discharge to website S2 smoothly.

The study situation of MAC Address and ARP list item is with aforesaid step S402 and step S403.If being slave site S3 and website S4, the message of learning MAC address and ARP list item comes, the outgoing interface with corresponding MAC Address and ARP list item is L1, namely use L1 to send message to website S3 and website S4, if being slave site S2, the message of learning MAC address and ARP list item comes, the outgoing interface with corresponding MAC Address and ARP list item is L1.1, namely uses L1.1 to send message to website S2.

Multicast or broadcasting packet are still selected to forward from L1.1, and forbid forwarding from L1.Just, the member interface of L1.1 only has logic interface R1 at this moment.

Situation on website S3, website S4 need not to create virtual polymerization sub-interface with website S1 on website S2, only the member interface in configuration polymerization interface on website need to be adjusted into the R1 gating, gets final product as the polymerization interface that arranges on this website.

Wherein, when the fault recovery of the corresponding node of logic interface R2 in website S2, the member interface of L1.1 in website S1, website S3 and website S4 is adjusted into logic interface R1 and logic interface R2, the member interface of L1 in website S2 is adjusted into logic interface R1 and logic interface R2 gating, get final product as the polymerization interface that arranges on this website, when the fault recovery of the corresponding node of logic interface R3, processing procedure similarly.

It is to be noted, in two kinds of above-mentioned situations, because the node that breaks down all is positioned on website S2, therefore, virtual polymerization sub-interface is not set on S2, but according to the situation of fault recovery, in the polymerization interface, which logic interface of gating need to be adjusted according to failure condition as member interface.

In addition, if the fault of logic interface R2 and the corresponding node of logic interface R3 is all recovered, delete L1.1 in website S1, website S3 and website S4, the member interface of the L1 in website S2 is adjusted into logic interface R1, logic interface R2 and logic interface R3.
