Embodiment Construction

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] Figure 4 is a flow chart of the partial route recovery method provided by the embodiment of the present invention, such as Figure 4 As shown, the steps include:

[0040] Step S101: According to the core network elements, the core network links formed between the core network elements, the bandwidth utilization rate, and the services carried by the core network links, it is determined that the core network link can be restored when the core network link fails. A recovery route for services carried by the failed core network link.

[0041] Specifically, according to the system command, determine the core network elements, core network links and b...

Abstract

The invention discloses a method and device for restoring local routes, which relate to a communication network. For the business carried by the link, determine the recovery route used to restore the business carried by the failed core network link when the core network link fails; monitor the failure of the core network link; when a certain core network link is detected When a link fails, the service data on the failed core network link is sent via the previously determined recovery route of the service. In the present invention, when core network link faults such as optical fiber interruption occur in the core network, local route recovery can be performed on affected services according to the pre-stored recovery route, thereby greatly improving recovery efficiency and reducing processing difficulty.

Description

technical field [0001] The invention relates to a communication network, in particular to a method and device for restoring a local route. Background technique [0002] In a communication network, the network is composed of many communication device nodes, and these network nodes are called network elements. Network elements are connected through communication lines, including various forms such as optical fiber cables. Network elements are distributed in various regions. For example, some network elements are located in laboratories of communication buildings in cities, and some network elements are located in remote areas. However, the equipment of these network elements needs to be configured, maintained and monitored, and it is impossible to send people on duty everywhere. This requires a central network management and control system, which is placed in the central computer room, and configures and maintains each node on the network through remote communication. and mo...
