Title: Design and analysis of local area network protocols for distributed real-time systems

Abstract: "Local area networks are steadily increasing their range of applications. While interconnection of computers and resource sharing has been typical of their applications, it is their envisioned role in distributed real-time systems which is receiving increased attention. The goal of this research is twofold: to design a multiaccess protocol for local area networks which better suits the requirement of a distributed real-time system; and to provide an analytical tool that can be used to study multiaccess protocols for bus networks in a unified manner.

Distributed real-time systems are characterized by their timing constraints. A substantial overhead is often incurred by the synchronization of the real-time processes running on different processors. This overhead can be reduced if there are guarantees on how fast messages are moved across the communication network. After examining the limitations of the standard protocols in providing such guarantees, we propose and study a virtual token protocol suitable for handling time-constrained messages in a distributed real-time system. The proposed protocol preserves the main advantages of the standard CSMA/CD and token passing standard schemes and remedies their principal shortcomings. As a result, the new protocol closely approximates an ideal priority scheme.

The global behavior of a class of multiaccess scheme for bus networks is characterized by a transmission phase, a resolution phase and an idle phase. We abstract a general mathematical model that can represent various multiaccess protocols for bus networks. The proposed model is based on the supplementary variables approach. We show that the use of this method results in a mathematically tractable system of state equations. While the proposed model is general, it can serve as a useful tool to compare various protocols for local area networks."
