Embodiment 1

[0086] The first embodiment provides a method for dynamic switching of rerouting services in a transport network, such as figure 1 Shown: Methods include:

[0087] S101: The network management analyzes the received device alarm command, determines the network element at the alarm point, and analyzes and obtains the path-finding start point and path-finding end point of the service failure.

[0088] In the existing telecom network management, the end-to-end services may be interrupted due to fiber connection / single disk failure. At this time, the fault point device will send an alarm notification, and the network management can analyze the specific alarm information after receiving the alarm information. If the fault information is caused by connecting fibers or a single disk, the network management needs to re-select a new path between the path-finding start point and path-finding end point to replace the faulty service path to ensure the normal communication of the line.

Embodiment 2

[0172] A device for dynamic switching of rerouting services in a transport network, the device includes:

[0173] at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being programmed to execute the first embodiment provided A method for dynamic switching of rerouting services in a transport network.

[0174] like Figure 12 As shown, it is a schematic diagram of a device for dynamic switching of rerouting services based on a transport network according to an embodiment of the present invention. The device for dynamic switching based on transport network rerouting services in this embodiment includes one or more processors 21 and a memory 22 . in, Figure 12 Take one processor 21 as an example.

[0175] The processor 21 and the memory 22 can be connected by a bus or in other ways, Figure 4 Take the connection through the bus as an exa...

Abstract

The invention discloses a method and device for dynamic switching of rerouting services of a transmission network. The method includes: a network management analyzes a received device alarm command, determines an alarm point network element, analyzes and obtains a path-finding start point and a path-finding point for service failures. the end point of the path; the network management initiates a rerouting command to calculate the path between the start point of the path finding and the end point of the path finding to obtain a normal path; for the normal path obtained by calculation, delete the original faulty path on the device configuration, activate and download the configuration of the normal path to the device; after the configuration is downloaded successfully, replace the faulty path to restore service communication, reroute and replace the connection successfully, and complete the service switching. The normal path segment and normal network elements of the original path are reused during the pathfinding process. When the pathfinding start point and pathfinding end point are used for pathfinding, the number of network elements to be searched for pathfinding can be reduced, which helps to improve the pathfinding efficiency.

Description

technical field [0001] The invention belongs to the field of service rerouting in telecommunication network management, and more particularly, relates to a method and device for dynamic switching of rerouting services in a transport network. Background technique [0002] In optical networks, especially in intelligent optical networks (Intelligent Optical Network, abbreviated: ION), with the increase of network operation time and the increase of the number of connections established and deleted in the network, the use of resources is likely to be unreasonable, affecting network operations. At this time, it is necessary to adjust the routing of some existing connections in the network to optimize the use of network resources. In addition, in the process of network operation, network maintenance work may be required to adjust network resources, such as adding nodes or links. During the process of resource adjustment, some connections may be affected. Therefore, Affected connec...
