STP-ISS Transport Protocol Overview and Modeling

Abstract

The paper is concerned with the development of the Transport protocol “STP-ISS” for SpaceWire networks. Firstly we give a brief overview of transport protocols which are intended to operate over SpaceWire: RMAP, CCSDS PTP, STUP, JRDDP and STP. Hereinafter, the paper presents the first revision of the new STP-ISS transport protocol which was developed in accordance with the results of the overview and technical requirements to the transport protocol. Finally, we describe STP-ISS modeling, which was very efficient for the STP-ISS protocol development, testing, analysis and improvement. This paper describes three modeling directions: C++ reference code, SDL-specification and SystemC network model
