Embodiment Construction

[0060] In the present invention, by modifying the selective receiving end model of the self-healing protection technology using dual transmission and selective receiving, the model of the selective receiving end service sink broadcast is established, and the corresponding switching protocol is designed based on the service sink broadcasting model, and according to the switching protocol, when a fault occurs in the network When the network is faulty, switch all the service connections carried on the working channel to the standby channel to ensure the normal connection of the service; when the network fault is eliminated, all the service connections carried on the standby channel are switched to the working channel in the switching recoverable mode .

[0061] The solution provided by the present invention focuses on the root cause of the above-mentioned protection failure problem. In the dual transmission and selective reception model, the protection failure is caused by the sel...

Abstract

The invention relates to a method and device providing network self-healing protection, which is mainly consisted of: firstly, the service of selective receiving terminal is set to a multicast sending mode under a double sending selective receiving mode, then all the services corresponding to the operation source in the operation channel are switched to the corresponding protection source in the protection channel when fault occurs in the operatino channel. The invention solves the problem of failed protection due to the coexisted multi-self-healing protection, and provides a high reliable service transfer, meanwhile, the invention provides a protection and switch protocol for the self-healing protection technique wherein a broadcast mode is adopted by the service place, and provides a solution for the application of service place broadcast mode in the self-healing protection technique.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a technology capable of realizing network self-healing protection. Background technique [0002] For networks, especially telecommunication networks, it is very important to ensure the reliability of network transmission, and this reliability needs to rely on the way of self-healing protection objectively. At present, communication networks can use multiplex section ring protection, channel ring protection, linear 1:1 multiplex section protection, linear 1+1 multiplex section protection (1+1LMSP) and end-to-end SNCP (subnet connection protection). ) and other self-healing protection measures. In practical applications, multiple protection coexistence methods are often selected according to different network topologies to ensure that service connections can be quickly restored when a network failure occurs, providing high reliability for service transmission.
