Abstract
The present invention relates to a convergence method and a device for a mesh network based on the VPLS dual homing. Before a dual-homing main link is faulty, the mapping relations between the dual-homing main link and all of communication devices are stored on a dual-homing device; when the dual-homing main link is faulty, the MAC addresses learnt from the dual-homing main link can be rapidly revoked, whereas the MAC addresses having no relations with the dual-homing main link remain, therefore a great deal of broadcast messages in the network is reduced, and the convergency speed of the network is increased.
Description
Technical field
The present invention relates to the communication technology, relate in particular to a kind of convergence method and device based on the dual-homed fully-connected network of VPLS.
Background technology
Along with social development and global economic integration, the more and more enterprises distribution enlarges day by day, employee's flowability also constantly increases, pressing for telecom operators provides link to connect, so that enterprise all includes each branch in the enterprise network of oneself, and make things convenient for the place of enterprise staff beyond enterprise also can conveniently visit the network of enterprises, just look like that they are in the same network.
Along with the extensive use of IP technology, utilize existing IP network to provide focus low-cost, that manageable dedicated network has become each big operator gradually for enterprise.Therefore, a kind ofly VPN is provided on IP network (Virtual Private Network: service Virtual Private Network), can conveniently set arbitrary velocity, the utilization of the simple technology of configuration and give birth to, this technology is MPLS (Multiple Protocol Label Switch: multiprotocol label switching) vpn service.Vpn service based on MPLS has two kinds, be respectively L3VPN (Layer3VPN: Layer3 Virtual Private Network) and L2VPN (Layer2 VPN: Layer 2 virtual private network), wherein L2VPN includes VPLS (Virtual Private LAN Service: the networking application model Virtual Private Network service).VPLS can realize the networking application model of multiple spot to multiple spot.VPLS provides a kind of more complete solution for the operator of the L2VPN business of many original use point-to-points.
VPLS makes the user site access network that disperses on the geographical position, and visit mutually just looks like that these websites directly insert LAN (Local Area Network: local area network (LAN)) go up equally.It is a kind of a kind of business that similar LAN service is provided on the MPLS network.The forwarding mechanism of VPLS simulation Ethernet (Ethernet): to destination address is that the message of broadcasting, multicast and unknown unicast address carries out inundation, and the source MAC of message is learnt, and target MAC (Media Access Control) address such as transmits at mechanism.In VPLS, in order to guarantee connectedness, each PE (Provider Edge; Provider edge equipment) adopt the full topological structure that connects between, for fear of the loop between the PE, the message that regulation is received from PE can not be transmitted to other PE, promptly horizontal cutting techniques again.
Set up the full lsp tunnel that connects between all pe routers that the VPLS solution need provide VPLS to serve,, must between pe router, set up n* (n-1)/2 a pw (PseudoWire for each VPLS example; But these are all generated by signaling protocol pseudo-line).In addition, the VPLS solution can also connect by classification, and promptly VPLS link pw and dual-homed main/slave link pw have formed HVPLS jointly.For convenience, follow-up link pw is referred to as hub pw, and follow-up dual-homed main/slave link is referred to as spokepw.So the VPLS solution comprises two kinds of patterns usually, a kind of is common VPLS, and a kind of is H-VPLS.For common VPLS solution, dual-homed equipment is user CE (Customer Edge; Customer edge), for the H-VPLS solution, generally all need dual-homed to PE/NPE with MTU/UPE.Based on the dual-homed operation principle of common VPLS and H-VPLS is similar, and here, we are that example illustrates with H-VPLS,
With reference to figure 1, Fig. 1 is based on the dual-homed fully-connected network topology schematic diagram of H-VPLS.In Fig. 1, dual-homed equipment is that (Multi-Tenant Unit: the multiple spot accommodation unit), main equipment is PE1-rs to MTU, and stand-by equipment is PE2-rs.Dual-homed primary link is pw1, and dual-homed reserve link is pw2.Under normal circumstances, have only dual-homed primary link pw1 to be in active state, dual-homed reserve link pw2 is in blocked state, PE1-rs is by the pw1 study MAC Address from user site 1 and user site 2, and PE2-rs, PE3-rs and PE4-rs are by the signaling relation study of being set up with the PE1-rs MAC Address from user site 1 and 2.With reference to figure 2, Fig. 2 carries out the schematic diagram of masterslave switchover after breaking down for pw1.
After pw1 breaks down, need be switched to standby pw2, as shown in Figure 2, at this moment PE2-rs just becomes main equipment, simultaneously originally at this VSI (Virtual Switch Instance; Virtual switch instance) inside also can arrive PE2-rs by standby pw2 from CE1 and the next flow of CE2.After the dual-homed primary link of H-VPLS breaks down, MTU can remove the MAC Address of originally learning from PE1-rs in this VSI, and carry the MAC tabulation to the PE2-rs transmission and cancel message for empty LDP address, after PE2-rs receives this message, can cancel all MAC Address of learning from PE1-rs in this VSI, after this other PE equipment that can be in fully-connected network send and carry the MAC tabulation and cancel message for empty LDP address, after other PE equipment are received this operation, do the operation same with PE2-rs.From existing technical scheme, we as can be seen owing to only be that pw1 breaks down, PE2-rs, PE3-rs and PE4-rs only need cancel the MAC Address of coming from pw1 study, there is no need to cancel all MAC Address of this VSI that comes from main equipment PE1-rs study.Owing to cancelled many MAC Address that are not subjected to topology change affects, the heavy learning process that can cause this MAC Address, because the study to unknown target MAC (Media Access Control) address need send broadcasting packet, also just increased simultaneously the number of broadcasting packet in the network, the number that connects the VSI that disposes in the number of PE-rs and the HVPLS territory entirely along with HVPLS increases in addition, this problem will be more and more obvious, influenced the convergence rate of network and the deployment of HVPLS network simultaneously greatly.
