Description
Technical field
The present invention relates to field of communication transmission, particularly a kind of low order SNCP (Sub-Network Connection Protection, SNCP) route method and device set up.
Background technology
Current society is more and more big to the dependence of information, requires the transmission information that communication network can be promptly and accurately.More and more along with online information transmitted, the speed of transmission signals is more and more faster, in case network breaks down (for example in the civil engineering dig optical cable disconnected), will cause great damage.Therefore the survival ability of network is that the fail safe of network is first problem that will consider.
When breaking down (for example optical fiber is disconnected) at network; Need not human intervention; Network in the extremely short time (International Telecommunication Union-TelecommunicationStandardization Sector, the ITU-T of ITU Telecommunication Standardization Sector is defined as in the 50ms), makes business from fault, recover transmission automatically automatically; The almost imperceptible network of user is out of order, is called self-healed protection.Its basic principle is that network will possess the ability of finding to substitute transmission route and rebuliding communication.Alternative route can adopt stand-by equipment or utilize the redundant ability in the existing equipment, to satisfy all or the professional recovery of assigned priority.Self-healed protection only is with the business recovery that lost efficacy---through alternate channel; And do not relate to the reparation or the replacing of the parts and the circuit of concrete fault, so the reparation of fault point still needs manual intervention to accomplish, the optical cable that has for example broken also needs artificial the reparation.
SNCP is a kind of of self-healed protection, and SNCP protection mechanism fundamental diagram of the prior art is as shown in Figure 1.The transmission path of service signal is divided into operating path and protection path, and end is two in the source sends out its operating path and the identical business of protection path carrying for service signal; Service signal selects receipts at Su Duan.Under normal circumstances, the service signal of place end selective reception operating path.When the service signal that interrupts or transmitted when operating path corrupted to a certain degree, Su Duan switched, the service signal that selective reception is transmitted on the protection path.Because work is identical with the business in protection path, therefore played the effect of self-healed protection, guaranteed the fault recovery of service signal.
In ASON, transmission equipment has certain " intelligence ", under the situation of service disconnection, can recomputate the professional route that makes new advances automatically, and makes business according to the route that newly calculates, and has guaranteed professional fault recovery.Intelligent network heavy-route protection sketch map of the prior art is as shown in Figure 2.Intelligent network among Fig. 2 is formed (shown in the imaginary point line among Fig. 2) by network element node A, B, C, D, E, F, G, Z, and service signal is linked into intelligent network and is transferred out by network element node Z from network element node A.Work as fiber break, during such as the fiber break between network element node E and the H, network element node E detects service failure, directly notifies access network element node A:E-H link failure through control plane then.After access network element node A receives signalling trouble, recomputate the new service path of getting rid of the E-H link, such as being: service path A-E-C-Z.At last, intelligent network is set up professional the connection on new service path, and removes original professional connection.
Protection low-order SNCP route sketch map of the prior art is as shown in Figure 3.Among the SNCP in tradition low order path, when work and protection route are all interrupted, because its 4 grades of virtual container (Virtual Container4; VC4) the service layer path is permanent connection; Even so there be the 3rd available route, also can't recover automatically, cause service disconnection.If the dual transmitting and receiving section service layer path of SNCP is intelligent path; As shown in Figure 3 since SDH (Synchronous Digital Hierarchy, SDH) intelligent network of being made up of intelligent net element A, B, C has been passed through in the business between network element A and SDH network element B transmission; So; When working and protect route all to interrupt SNCP protection inefficacy, can also attempt heavy-route and seek new available route, carry out transport service through protecting VC4 Server Trail.The business recovery time, can be used as and prevented professional permanent stand-by protection mechanism of interrupting after SNCP lost efficacy to minute rank at 100ms.For path configurations method shown in Figure 3; Utilize the double grading of SNCP and intelligent heavy-route, can protect low-order service, but the existing collocation method of webmaster is very complicated; Its layoutprocedure is entirely manual configuration; And each configuration step is separate, can't accomplish curstomer-oriented to traffic transmission demand task, has reduced the efficient in configuration transport service protection path.
Summary of the invention
In view of this; The main purpose of the embodiment of the invention is to provide a kind of method and apparatus of setting up low-order SNCP route; Solve protection path configurations method complicacy in the prior art; Require the many problems of user's manual operations, reduced manually-operated risk, improved the efficient in configuration transport service protection path.
