SpaceFibre plug and play-based satellite-borne network management method

Abstract

The invention discloses a SpaceFibre plug and play-based satellite-borne network management method, belonging to application field of satellite-borne space buses. The method comprises the steps that aSpaceFibre bus network is constructed at first, and a SpaceFibre plug and play communication protocol is designed; then a network manager sends a device static port scan packet to routers, and a physical address of the network manager and a connection relationship of a router and another router are determined; finally, each order of router forwards a static scan packet to each terminal device toparse and reply, and the network manager receives a reply packet and then determines a physical address of each terminal device; the network manager monitors the bus network in real time and initiatesdynamic network scanning, identifies the quantity of routers and a connection state of every two routers automatically, and updates a network topological structure map after the device is plugged orunplugged; and the network manager controls the terminal device to send a data packet to the network manager. Network addressing is easy and convenient, fewer system space resources are used, the system performance is improved, and unnecessary workload is saved.

Description

technical field [0001] The invention belongs to the application field of spaceborne aerospace bus, in particular to a SpaceFibre-based plug-and-play spaceborne network management method. Background technique [0002] SpaceFibre is a high-speed and full-duplex aerospace serial bus. In the harsh environment of aerospace, it has high reliability, high stability, self-diagnosis and recovery capabilities. [0003] Plug and play originated in the field of computers, such as USB devices, which can be connected to almost all computers, and users can use the device within a few seconds; plug and play means that when the device is inserted into the computer system, It can be put into work without manual installation of drive equipment. On the basis of the SpaceFibre parent protocol, a plug-and-play protocol is designed, and the same protocol packet format is used to realize communication; in the plug-and-play standard, the concepts of network discovery, network configuration, servic...
