Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] as attached figure 1 , figure 2 As shown, a failure routing recovery method, the main node, the destination node and the surrounding neighbor nodes form a network, when the next hop node is found to be invalid, it will quickly select a suitable backup node from the set to replace the original failure node, so that there is a new The route to replace the disconnected original route. Each node will pe...

Abstract

The invention discloses a method of recovering a broken route. The implementation process of the method is as follows: based on a network constituted by a source routing node, a destination routing node, and a number of intermediate routing nodes, when next routing node in an information transmission link is broken, an appropriate node is chosen from the intermediate routing nodes as a backup node to take the place of the previous broken node, and thus, the disconnected routing node is replaced by a new routing node. Compared with the prior art, the method of recovering a broken route has the advantages that a traditional backup routing mechanism is modified to a backup node mechanism, providing better flexibility and successfully solving the broken route recovery problem. Moreover, compared with maintenance of the backup routing mechanism, the method is simpler and better in practicality.

Description

technical field [0001] The invention relates to the technical field of computer application, in particular to a highly practical and invalid route recovery method. Background technique [0002] A scalable server system generally consists of multiple computing nodes. Routing and topological structures between different computing nodes are generally complex. A transmission path is established between the master node and the destination node. Once the transmission is interrupted, the existing route cannot be repaired in a short period of time. The node will be delayed or completely invalidated, and the packet transmission path will be blocked. [0003] In order to solve the route failure problem, the easiest way is to re-establish a path, but this will bring long waiting time and delay. The existing general practice is to use the backup routing method to restore the failed route, that is, in the process of path finding, while the path used for the official transmission is det...
