Problems solved by technology

[0003] (1) In a power line network, a single active routing is slow in response to a power line channel with a high time-varying nature when the channel suddenly deteriorates.
[0004] (2) On-demand driving routing In the case of long initial pathfinding delay or high time-varying power line channel environment, the dynamically searched route may fail quickly. When a business occurs, it needs to find the path again, which cannot meet the business needs.
[0005] (3) Hybrid routing makes up for some defects of proactive and on-demand routing to a certain extent, but the existing hybrid routing protocols cannot adapt to power line networks

Embodiment Construction

[0018] Such as figure 1 As shown, this method for repairing routing under the power line network includes the following steps:

[0019] (1) Repair the next hop of the failed path;

[0020] (2) If step (1) fails to repair, repair the intermediate node;

[0021] (3) If step (2) fails to repair, repair the source node.

[0022] The routing method of the present invention belongs to a hybrid routing protocol. When the path formed by the active routing protocol fails, according to the three repair strategies of repairing the next hop of the failed path, repairing the intermediate node, and repairing the source node, the active type The path generated by the routing protocol is repaired, which is very suitable for the power line channel environment.

[0023] In addition, such as figure 2 As shown, S-P1-P2-D1, S-P1-P2-D2, S-P1-P2-Dn, n paths, if P1 and P2 are disconnected, if you directly use the point-to-point path finding , The path may be triggered 3 times. If the link between P1 and P...

Abstract

The present application discloses a method for repairing routing in a power line network, which can repair a failure path generated by an active routing protocol, and is suitable for a power line channel environment. The method for repairing routing under the power line network includes the steps of: (1) repairing the next hop of the failure path; (2) repairing the intermediate node if step (1) fails to repair; (3) repairing the intermediate node if step (2) repairs Failed, repair the source end node. Devices using the method are also provided.

Description

Technical field [0001] The present invention relates to the technical field of communication routing, in particular to a method for repairing routing under a power line network, and a device using the system. Background technique [0002] Existing routing protocols can be divided into three categories: active routing, on-demand-driven routing, and hybrid routing (combination of active routing and on-demand routing). The respective defects are as follows: [0003] (1) In the power line network, a single active router faces a power line channel with high time variability. When the channel suddenly deteriorates, the route response is slow. [0004] (2) On-demand-driven routing. In the power line channel environment with long initial path-finding delay or high time-varying power line channel environment, the dynamically searched routing may quickly fail. When a service occurs, it needs to find the path again, which cannot meet the service requirements. . [0005] (3) Hybrid routing make...
