Abstract

The invention discloses a multicast routing method based on a RapidIO switching network, and electronic equipment. The multicast routing method based on the RapidIO switching network comprises the following steps: configuring at least one group of multicast to generate a configuration file, analyzing the configuration file by utilizing a core node to obtain a switching node where a source node islocated, that is a source switching node, and a the switching node where a destination node is located, that is a destination switching node, calculating the shortest path between the source switchingnode and the destination switching node, selecting a unique shortest path, recording the information of all switching nodes in the unique shortest path, and finally performing multicast routing configuration on a switch after the recording of all paths is finished. The data processing efficiency of the system and the flexibility and universality of RapidIO switching network data transmission areimproved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a multicast routing method and electronic equipment based on a RapidIO switching network. Background technique [0002] RapidIO technology is a high-performance, low-pin-count crossbar interconnection technology based on packet switching, and is an international standard for high-speed interconnection of embedded systems. RapidIO adopts the way of interconnection and exchange for data transmission, which breaks the previous single point-to-point transmission mode and improves the flexibility of the system. In systems interconnected based on RapidIO switches, especially embedded real-time systems, multicast data and messages are often required. In order to support the application requirements of multicast, the "Multicast Extensions Specification" (MulticastExtensionsSpecification) is specially defined in the RapidIO interconnection specification. In the RapidIO interconnection...
