Description
Technical field
The present invention relates to the Packet Transport Network field; relate in particular to a kind of T-MPLS (Transport-MultiProtocol Label Switching; transmit multiprotocol label switching) looped network protection MEG (Maintenance Entity Group, Maintenance Entity) collocation method and device.
Background technology
Transmit the host in the metropolitan area network and will adopt the looped network framework, ethernet technology will reach the carrier class requirement, and high reliability is that it at first needs the problem that solves.The carrier class Ethernet utilizes ring-network topology, when the network equipment or link occurs fault, can fast and effeciently switch on the backup link, and guarantee existing professional unaffectedly, reaches the requirement that the protection of 50ms is switched.T-MPLS is the grouping tranmission techniques that ITU-T (InternationalTelecommunication Union Telecommunication Standardization Sector, International Telecommunications Union's telecommunication standards group) recommends.Along with the continuous maturation of T-MPLS technology and perfect; the extensive configuration of T-MPLS network; TM-SPRing (T-MPLS protection rings) technology at T-MPLS also will be adopted by operator gradually, reaches the reliability and the manageability requirement of carrier class Ethernet.
T-MPLS connects same SDH (Synchronous Digital Hierarchy; SDH (Synchronous Digital Hierarchy)) connects the time stability that equally has than long; therefore can implementation of class switch and OAM (Operation like the protection among the SDH; Administration and Management, operation management maintain) mechanism.T-MPLS looped network protection technology is exactly the technology of in TM-SPRing business being protected fast.The T-MPLS protection rings is made up of T-MPLS multiplex section layer (T-MPLS Section Layer is called for short the TMS layer) and T-MPLS path layer (T-MPLS Path layer).The multiplex section layer detects the connectedness between two nodes and transmits APS (Automatic ProtectionSwitching, APS) information by OAM mechanism; Path layer is exactly the tunnel layer of common indication, is generally the twin nuclei that one or more tunnel constitutes, and the Business Stream direction of two rings is opposite, is clockwise and counterclockwise, is standard according to the direction of business, is divided into building ring and guard ring.Generally speaking, business transmits on building ring, and after the adjacent node section lost efficacy, TM-SRPing had two kinds of protection mechanisms: source routing (Steering) mode and loopback (Wrapping) mode.What adopt at present is the Wrapping mode, and after the adjacent node section lost efficacy, the node of close fault was looped back to data flow on the guard ring, transmits the arrival destination node through long path.Suppose that one adopts the T-MPLS protection rings of Wrapping mode; a business is arranged: the business between network element 1 and the network element 2 (being called for short 12 business) on the building ring; (be called for short tunnel 1 by work tunnel; be assumed to be clockwise direction) transmit; the source node of work tunnel is that network element 1 is by No. 9 GE mouth receipts/sending services; destination node is that network element 2 passes through No. 9 GE mouth receipts/sending services, and intermediate node is that network element 3 is by No. 9 and No. 10 GE mouth receipts/sending services.Have a protection tunnel (be called for short tunnel 2, be assumed to be counterclockwise) on the guard ring, the protection tunnel is a loop tunnel, and all network elements of tunnel process all are intermediate node.When network element 3 and 2 of network elements break down; fault down stream adjacent node network element 2 detects fault at this moment; and sending switching request to fault upstream neighbor node network element 3 by the APS agreement, network element 3 can switch the business on the protection tunnel 2 on the rightabout guard ring and transmit.For example, professional normal direction of transfer is 1-3-2, if disconnected fine between the 3-2, the service needed of 3-2 direction changes away 3-1 into.
G.8132 defined T-MPLS looped network protection scheme, described, be similar to the T-MPLS looped network protection switching structure of SDH protection rings, transmitted according to the defect monitoring of section layer or APS protocol information and carry out professional protection based on the mechanism of turning back etc.Specific implementation is: the T-MPLS annular connects, and all will dispose MEP (Maintenance Entity Point, maintenance entity end points) on each node on the ring, as shown in Figure 1.Dispose TMS (being multiplex section) between the adjacent MEP, one group of tunnel that passes through good at managing on the multiplex section.Carrying out CV (Connectivity Verification, detection of connectivity) on the ring between adjacent two nodes detects.Under the normal condition, send the APS message between the adjacent MEP of each node on the guard ring.When certain multiplex section breaks down, send the APS request message to adjacent MEP, carry out the tunnel and switch.A tunnel is arranged from A to B among Fig. 1, if between mep_a and mep_b, break down,, then send the APS handoff request to mep_a along the protection tunnel if mep_b detects fault, professional changing from D-E walks D-C, and the defective of D-C multiplex section layer monitors by MEG (DC); If mep_a detects fault, then to mep_b, business changes from E-D walks E-B around a circle in edge protection tunnel transmission APS request, and the defective of E-B multiplex section layer monitors by MEG (EB).
As seen; in the looped network protection; assigned work MEG and protection MEG are wanted in the configuration of protecting tunnel group; the MEG here is the TMS layer; and looped network protection is exactly the protection of TMS layer; the MEG of a direction protects by another rightabout MEG, and protected tunnel will have one section at least on this multiplex section ring.In the looped network protection; configured tunneling technique protection group TMS layer work MEG and protection MEG have following method: the work MEG and the protection MEG that directly manually specify the protecting tunnel group; and specify the looped network protection group; such shortcoming is; owing to manually select MEG, protected tunnel might appear not on the multiplex section at the MEG place of selecting, and cause the protecting tunnel configuration set to make mistakes; too strict in promptly existing the realization to the input data demand, cause arrangement abnormalities easily.
