Example Embodiment

[0040] Example one:

[0041] The network isolation fault recovery system using silent links in the communication network of the present invention includes:

[0042] First, each node device that composes the communication network runs a topology discovery protocol module, so that each node device obtains the topology of the entire network, and can perceive changes in the network topology in real time;

[0043] For a network device node in the network, one or more silent links are pre-configured, and the silent link is used to connect the local device node and the neighbor device node.

[0044] Further, the silent link is associated with two device nodes and is in an inactive state or a closed state.

[0045] Further, when the antenna on which the link depends is ambushed, so that the link cannot currently be used to transmit service information, the link is in an inactive or closed state. Only when the silent link is activated, after activation The link can transmit service signals.

Abstract

The invention belongs to the technical field of network isolation fault recovery when a communication network has a fault, and discloses a network isolation fault recovery system using a silent link in the communication network. The method comprises the steps that firstly, each node device forming a communication network operates a topology discovery protocol module, so that each node device obtains the topology of the whole network and can sense the change of the network topology in real time; for a network device node in a network, one or more silent links are pre-configured, the silent links being used to connect a local device node and a neighbor device node. According to the method, the silent link is automatically activated when the software protocol module judges network isolation, so that the network isolation fault is automatically relieved, and compared with an existing manual network isolation fault repairing technology, network communication can be quickly and automatically recovered, and long-time communication interruption is avoided.

Description

technical field [0001] The invention relates to the technical field of network isolation fault recovery when a communication network fails, in particular to a network isolation fault recovery system using silent links in the communication network. Background technique [0002] In the existing communication network, the network topology and communication resources are pre-deployed, and the device nodes and links that make up the network topology are all activated so that they can provide services for customer business data transmission in real time. When the network topology changes and communication resources fail, and it is so serious that the different network parts in the network topology are completely isolated and no new available routes can be provided for customer business data, it is often necessary to manually repair this network isolation fault. , such as creating or reconnecting disconnected optical fiber links, resulting in relatively long service interruptions. ...
