Plug and Play for SpaceWire Networks: Centralized Algorithm

Abstract

SpaceWire solves the problem of communication protocol to the existing on-board equipment. This standard was developed for the network nodes and switches interconnected via high-speed bidirectional serial connection. The communication network can be quite large, thus forming another problem - setting and monitoring of connections / disconnections in the network. Plug and Play - an algorithm for computer-aided learning of the network and setting up basic configuration of devices and connections. In other words, without a human operator the switches will be configured with routing tables and the nodes will be given logical address. There are two types of algorithms: the centralized and decentralized. In this paper we look at the centralized algorithm for computer-aided learning of the network and setting up the network settings. We show the results of simulating this algorithm and make some conclusions.
