specific Embodiment approach 1

[0015] Specific implementation mode 1. Combination figure 1 Illustrate this specific embodiment, a kind of SpaceWire dynamic routing implementation method, its method is: after the newly added SpaceWire node (has unique logical address) joins the network, at first broadcast and send a routing request data packet, carry this data packet in this data packet The logical address and description information of the SpaceWire node (for example, which resources it has can be used and other information, so that it can be recognized and used by other devices in the system). When the SpaceWire router in the network system received this packet, it updated the physical address in the routing request packet (increase the port number to the physical address of the routing request packet) according to the corresponding physical port of the routing request packet received. domain), the broadcast is forwarded, and the routing table is updated according to the logical address of the SpaceWire no...

Abstract

A method for realizing spaceWire dynamic routing relates to a method for realizing spaceWire routing. It aims to solve the problem that existing SpaceWire routers are all static routers, resulting in poor application flexibility and poor scalability of the spaceWire network. The method: after the newly added SpaceWire node joins the network, it first broadcasts a routing request packet, and when the SpaceWire router in the network system receives this packet, it updates the physical address in the routing request packet according to the corresponding physical port and broadcasts Forward, update the routing table. After other SpaceWire nodes update the stored other node information and add their own relevant information, they form a routing request reply data packet and send it to the newly added SpaceWire node. When the routing request reply data packet passes through the SpaceWire router, the SpaceWire router updates the physical address in the data packet and forwards it to the newly added SpaceWire node. After the newly added SpaceWire node receives the routing request reply data packet, it updates the stored relevant information of other nodes. The present invention is suitable for dynamic route establishment in communication process.

Description

technical field [0001] The invention relates to a method for implementing SpaceWire routing. Background technique [0002] According to the SpaceWire specification ECSS-E-50-12A standard, the SpaceWire router must support the dynamic routing mechanism, that is, the SpaceWire router can change the routing dynamically and frequently based on the data packets. The routers implemented now are all static routers, that is, the routing table in the router is fixed. Therefore, this type of router cannot conform to the ECSS-E-50-12A specification well, and has poor flexibility in practical engineering applications, and the corresponding SpaceWire network has poor scalability. Contents of the invention [0003] The invention aims to solve the problems that existing SpaceWire routers are all static routers, resulting in poor application flexibility and poor expandability of the SpaceWire network, thereby providing a method for implementing SpaceWire dynamic routing. [0004] A meth...
