Abstract

The present invention provides a method and device for service multi-path protection, the method comprising: establishing a protection path group including multiple protection paths for the working path of the service, and selecting a preferred protection path in the protection path group; when the When the working path fails, the service is switched to the preferred protection path. According to the invention, multi-path protection can be provided for services.

Description

technical field [0001] The invention relates to the field of service protection, in particular to a method and device for service multi-path protection. Background technique [0002] With the wide application of multi-service bearer and PTN (Packet Transport Network, Packet Transport Network) technology, especially in the operation network, the demand for service reliability is increasingly urgent. How to ensure the survivability of services when the network management fails has become a major concern of operators. In the current network, automatic protection switching (APS) technology is mainly used to ensure the survival of services after encountering failures. That is, the working transmission path of the service is bound to a selected protection transmission path to form a protection group; when the working path fails and fails, the service is migrated to the protection path for transmission. Currently, according to the relationship between the working path and the pro...
