RapidIO route configuration method and device based on VPX system

Abstract

The invention relates to a RapidIO route configuration device and a RapidIO route configuration method based on a VPX system. The device comprises an upper computer and a VPX system, wherein a node in a RapidIO network of the VPX system serves as a RapidIO main node; the upper computer is used for building a corresponding RapidIO route model according to the network topological structure of the VPX system, and also used for traversing the whole RapidIO route model, computing an optimal path between any two RapidIO nodes in the model according to path weights, forming a route configuration table and transmitting the route configuration table to the RapidIO main node in the VPX system; and the RapidIO main node is used for performing route configuration on the whole RapidIO network of the VPX system according to the route configuration table.According to the device and the method provided by the invention, the upper computer is responsible for computing the route configuration table of the RapidIO network, and then configuration is performed by the RapidIO main node in the VPX system; compared with a traditional single-point configuration method, the method provided by the invention is significantly improved in configuration speed and configuration accuracy via cooperative configuration of the upper computer and the RapidIO main node.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a RapidIO routing configuration device and method based on a VPX system. Background technique [0002] There are relatively few published research results based on RapidIO routing configuration in the industry, and most of them are based on the Linux kernel provided by the RapidIO protocol, traversing the entire network from a single master node. [0003] The current improvement work mainly focuses on improving the traversal algorithm provided by the original Linux kernel, but this method has great limitations. First of all, this method is not feasible for systems where the operating system of the master node is not Linux; secondly, this method still starts from a single point to discover the routing status of the entire network, and according to the relevant knowledge of graph theory, a single It is very difficult to find the best routing information of any two nodes othe...
