Analysis of real-time backplane bus network based on write posting

Abstract

The backplane bus network protocol is a mechanism to facilitate the standard networking on the backplane bus. Usually a link-level network protocol is designed and implemented to provide the bus networking. In this paper we introduce a scheduling analysis for real-time communication in the backplane network. Unlike traditional communication analysis, we must consider the write posting, a feature of the bus interface which improves the overall schedulability dramatically. For an exact real-time analysis, a methodology is also developed to model the timing behavior of the bus.
