Integrating local area networks to improve reliability and performance

University of British Columbia

A hybrid network comprising an Ethernet and a Cambridge Ring has been proposed by researchers in the Department of Computer Science at the University of British Columbia as a means for improving reliablility and performance of computer communication in a local area network environment. This thesis explores the practicability of this concept and constructs a generalization of this model, where an arbitrary number of LANs, of arbitrary technologies, may be used together in an integrated fashion. The goal is a set of software primitives which provides a connection-oriented message-based IPC interface, and allows a user to utilize multiple networks with relative ease. A number of relevent design issues, including host reachability, path selection, and load monitoring are dealt with in detail. Also discussed is an implementation of this software interface here at the University of British Columbia, developed on Sun workstations running 4.2 BSD Unix which are inter-connected by an Ethernet and a Cambridge Ring. Measurement results on the performance of the implemented software are included.
