Compared with prior art, the present invention has the following advantages:
By using technical scheme of the present invention, solved when realizing the interface converging operation in the RPR system, when a node on certain annular link breaks down, cause the full annular link unavailable, influence the problem of network service, by set up the mode of corresponding virtual polymerization sub-interface according to malfunctioning node, in minute faulty link, carry out network service, 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.
Be example equally with as shown in Figure 1 application scenarios, comprise S1, S2, four websites of S3, S4 in the RPR looped network, be connected by three annular links of ring1, ring2 and ring3 (being previously described ring) between each website, logic interface with the corresponding RPR node of each annular link on each website is respectively R1, R2 and R3, setting up the polymerization interface on each website respectively is L1, wherein, L1 comprises R1, R2 and R3 simultaneously.
As shown in Figure 2, when the node of the last ring3 of website S2 breaks down (the logic interface R3 on the website S2 can't connect), on the polymerization interface on S1, S3, the S4, increase the virtual polymerization sub-interface of an inside.Because the processing on S1, S3, the S4 is identical, below be that example describes with the processing procedure of website S1.
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 may further comprise the steps:
Set up virtual polymerization sub-interface among step S401, the website S1.
At first, the RPR logic interface of the ring1 on the website S1, ring2, the pairing node of ring3 is R1, R2 and R3, and the polymerization interface that comprises above-mentioned three logic interfaces is L1, further increases a virtual polymerization sub-interface L1.1 in this step.
The member interface of L1 is logic interface R1, logic interface R2 and logic interface R3, and the member interface of L1.1 has only the logic interface R1 and the logic interface R2 of normal node place ring among the website S1, does not promptly comprise the logic interface R3 that is positioned at identical ring among the website S1 with the malfunctioning node of website S2 among the 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 is created 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.
Internal virtual polymerization sub-interface is that website is created automatically according to the situation of RPR aggregation group interior nodes, when finding that certain RPR ring occurs down that node hinders for some reason and establishment when disappearing; Deletion this virtual polymerization sub-interface when the fault recovery of the node that disappears, the node disappearance in some RPR rings 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 the website S1, need to judge that message is which website is come, and handle accordingly according to judged result.
If the message of study MAC Address is to come from website S3 or website S4, then the outgoing interface of MAC Address is set to L1; If the message of study MAC Address is to come from website S2, then 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 promptly the interior polymeric sub-interface is invisible to the user.
Concrete, website is to judge according to the SMAC address of RPR head in the message that receives message is from which website to come.
Step S403, website S1 carry out the ARP study of other nodes.
When carrying out ARP study on the website S1, need to judge that message is which website is come, and handle accordingly according to judged result.
If the message of study ARP is to come from website S3 or website S4, then the outgoing interface of ARP list item is set to L1; If the message of study ARP is to come from website S2, then 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 promptly the interior polymeric interface is invisible to the user.
Concrete, website is to judge according to the SMAC address of RPR head in the message that receives message 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 influence 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, then execution in step S405;
If multicast message or broadcasting packet, then execution in step S406.
Step S405, transmit according to MAC Address list item, ARP list item.
When needing to transmit two layers of unicast message or three layers of unicast message on the website S1, then inquire about MAC Address list item or ARP list item, select to transmit according to the outgoing interface of list item from polymerization interface L1 or virtual polymerization sub-interface L1.1.
If the outgoing interface of list item is polymerization interface L1, then to describe as can be known according to above-mentioned setting, the message of this list item study is to come from website S3 or website S4, therefore, can share ring1, ring2, ring3 when transmitting on polymerization interface L1.
If the outgoing interface of list item is virtual polymerization sub-interface L1.1, then describe as can be known according to above-mentioned setting, the message of this list item study is to come from website S2, therefore, when on virtual polymerization sub-interface L1.1, transmitting, only can share ring1 and ring2, avoid the ring3 at the pairing logic interface R3 of malfunctioning node place, thereby, guarantee that website S2 can receive message.
Step S406, multicast, broadcasting packet are only transmitted from virtual polymerization sub-interface.
When needing forwarding multicasting or broadcasting packet on the website S1, owing to need to guarantee that message can receive from website S2, therefore, multicast or broadcasting packet can only be transmitted from virtual polymerization sub-interface L1.1, promptly share on ring1 and ring2.And, can not transmit from polymerization interface L1 again, otherwise other websites in the looped network will be received 2 parts of messages when virtual polymerization sub-interface L1.1 transmits.
On the specific implementation, guarantee that the method that multicast, broadcast traffic are only transmitted is on virtual polymerization sub-interface L1.1:
1) when being supported in this RPR looped network when directly forbidding being provided with of multicast, broadcast traffic on the polymerization interface, forbids on polymerization interface L1 that then multicast, broadcast traffic get final product.
2) when in this RPR looped network by multicast, broadcast interface tabulation carrying out multicast, when broadcast traffic is transmitted, then earlier the logic interface in the polymerization interface L1 is rejected from multicast, broadcast interface tabulation, again the logic interface in the virtual polymerization sub-interface L1.1 is added multicast, broadcast interface tabulation.
3) if three layers of multicast then because original related aggregation group is polymerization interface L1, need be updated to virtual polymerization sub-interface L1.1 at this moment.If adopt the form of interface list, then logic interface R3 (being the logic interface that differs between L1 and the L1.1) rejecting is got final product.
Whether step S407, failure judgement are recovered.
If do not recover, return step S404;
If recover, execution in step S408.
Step S408, website S1 delete virtual polymerization sub-interface.
Above flow process is to be that example describes with website S1, because website S3 and website S4 do not have fault to take place equally, so, corresponding flow process equally as shown in Figure 4, in this no longer repeat specification, but for website S2, because fault has taken place the logic interface on the node wherein, this logic interface can not normally carry out Business Processing again, so, polymerization interface among the website S2 directly changes to the L1 of logic interface R1 and logic interface R2 composition, therefore, because variation has taken place in the member interface itself in the polymerization interface, therefore, adopt the quick handover mechanism of existing polymerization to get final product, need not other modifications.
And on website S1, website S3 and the website S4,, therefore, need carry out extra process if realize quick switching because aggregation group changes.At first, the node failure that detects the corresponding ring3 of website S2 on website S1, website S3, website S4 (is the pairing node failure of logic interface R3 on the S2, this detection can be responded to fast by the RPR change in topology), then 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, then 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 that the deletion aggregation port is learnt down.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 the 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, delete virtual polymerization sub-interface L1.1 then.Multicast list then upgrades outgoing interface to be polymerization interface L1 or to increase logic interface R3 as outgoing interface.
