Local area computer communication networks

Abstract

In this thesis a number of local area network architectures are studied and the feasibility of a LSI design for a universal local network chip is considered. The thesis begins with a survey of current network technologies and a discussion of some of the problems encountered in local network design. Existing implementations of local networks are then discussed, and their performance compared. Ultimately the design considerations for a general purpose, microprogrammed, LSI network chip is discussed. Such a circuit is able to handle a range of network architectures and can be reconfigured to suit various traffic patterns. Finally some of the protocol requirements of local networks are discussed, leading to a redesign of the Cambridge ring to provide hardware support for protocol implementation.
