Description
Technical field
The present invention relates to field of network management, particularly a kind of mixed networking protecting method and device.
Background technology
The APS (APS-Automatic Protection Switching) of SDH (Synchronous Digital Hierarchy-SDH (Synchronous Digital Hierarchy)) network is a kind of redundancy protecting mechanism; G.783 and G.841 define by ITU, comprise polytypes such as Multiplex Section Shared Protection Ring, multiplex section special line guard ring, linear multiplex section protection.
Multiplex section protection is by every end detection fiber and equipment operation situation at multiplex section; under situation about noting abnormalities; send the protection switching request by the K1/K2 byte that is arranged in the multiplexing paragraph header (MSOH-Multiplex Section Over Header) of protecting passage, and switch the wrap protection that bridge joint is replied by the opposite end.Multiplex section protection exchanging mechanism is divided into 1: N and 1+1 dual mode, and 1: N service channel shared a protection passage in the N mode, and N is 14 to the maximum; Under the normal condition of not protecting switching request, the protection passage can be used for transmitting some supplementary services usually, and its redundancy is 1/N, and N is big more, and redundancy is more little; When a plurality of passages need application protection simultaneously, can only there be a passage can obtain protection.1+1 is a kind of 100% redundancy protecting mode, takes transmitting terminal fixing professional with transmission above the protection passage toward service aisle, selects top-quality one tunnel mode that receives at receiving terminal.1+1 redundancy protecting mode is divided into unidirectional switching and dual-ended switching according to switching direction; unidirectional switching is when fault takes place; only the business of out of order that direction can switch to above the protection passage; the another one direction keeps with original the same; and dual-ended switching can switch to the business above the both direction above the protection passage simultaneously; for the unidirectional switching of 1+1 pattern, can need not support of APS agreement and realization naturally.
Virtual Router Redundancy Protocol (VRRP-Virtual Router Redundency Protocol) is a kind of protocol for error tolerance, it guarantees when the next hop router of main frame breaks down, can replace by another router timely, thus continuity of keeping in communication and reliability.In order to make VRRP work, at first to create a virtual ip address and MAC Address, in this network, just added a virtual router like this, and the main frame on this network is communicated by letter with virtual router, need not to understand any information of physical router on this network.A virtual router is made up of an active router (Master) and several backup routers (Backup), and active router is realized real forwarding capability.When active router broke down, backup router became new active router, took over its work.
In present prior art; what the redundancy protecting major part of SDH network adopted is the APS technology; this just needs equipment must support the APS characteristic; when the master uses the work path failure; by APS flow being switched to backup path apace sends; this requires master/slave device except needs are supported the APS characteristic; also need between master/slave device, set up PGP (Protection Group Protocal protect group protocol) passage; when the master is broken down with operating path; realize switching between master/slave device by the PGP passage; the business that makes sends by stand-by equipment; so just more increased the input of equipment; but also limited bandwidth resources can have been wasted, also more complicated of the implementation method of the APS of SDH meanwhile.When SDH and Ethernet mixed networking, because the APS of SDH only is only applicable to the light networking, can't realize protection to Ethernet, duplicate protection how to realize SDH and Ethernet is one problem to be solved.
