Embodiment 1

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

[0087] S101: The network manager analyzes the received device alarm command, determines the alarm point network element, and analyzes the pathfinding start point and pathfinding end point of the service failure.

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

[0089] S102: The network manager initiates a rerouting c...

Embodiment 2

[0172] A device for dynamically switching rerouting services in a transport network, the device comprising:

[0173] At least one processor; and, a memory connected in communication with the at least one processor; wherein, the memory stores instructions executable by the at least one processor, and the instructions are programmed to perform claim 1- 9 Any one of the methods for dynamic switching of rerouting services in the transport network.

[0174] Such as Figure 12 As shown in FIG. 2 , it is a schematic diagram of equipment for dynamic switching of rerouting services based on transport network according to an embodiment of the present invention. The device for dynamically switching services based on transport network rerouting in this embodiment includes one or more processors 21 and memory 22 . in, Figure 12 A processor 21 is taken as an example.

[0175] Processor 21 and memory 22 can be connected by bus or other means, Figure 4 Take connection via bus as an exa...

Abstract

The invention discloses a method and equipment for dynamically switching a rerouting service of a transport network, and the method comprises the following steps: analyzing a received equipment alarm command by a network manager, judging to obtain an alarm point network element, and performing analyzing to obtain a path-finding starting point and a path-finding ending point of a service fault; initiating a rerouting command by the network manager, and carrying out path-finding calculation between the path-finding starting point and the path-finding ending point to obtain a normal path; for the normal path obtained through calculation, deleting the original fault path configuration on the equipment, and activating and downloading the configuration of the normal path to the equipment; after configuration downloading succeeds, replacing the fault path to recover service communication, and completing service switching after rerouting replacement connection succeeds. In the way-finding process, when the normal path segment and the normal network element of the original path are reused, and the way-finding starting point and the way-finding ending point are used for way-finding, the number of network elements needing to be found in way-finding can be reduced, and the way-finding efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of service rerouting in telecommunication network management, and more specifically relates to a method and equipment for dynamically switching rerouting services in a transport network. Background technique [0002] In optical networks, especially in Intelligent Optical Networks (Intelligent Optical Network, abbreviation: ION), as the network operation time increases, the number of connections established and deleted in the network increases, and the use of resources is likely to be unreasonable, affecting network operations. In this case, it is necessary to adjust the routing of some existing connections in the network to optimize the use of network resources. In addition, during the operation of the network, it may be necessary to carry out network maintenance work to adjust network resources, such as adding nodes or links. During the process of resource adjustment, some connections may be affected. For this reason...
