Protocol for deterministic data delivery in SpaceWire networks

Abstract

The paper presents a new scheduling protocol for SpaceWire networks which provides deterministic data delivery in the network and performs arbitration of data coming from several transport protocols. Firstly, we give an overview of TDMA-based network protocols that have been developed for the ground-based and onboard networks. Then, we present a new scheduling protocol which is based on the STP-ISS scheduling mechanism and extended with additional features.
