Local Computer Network Technologies covers the considerable amount of work accomplished in developing link access protocols for ring and bus computer-communication networks. This three-chapter book systematically discusses both of these protocols and their associated performance models. Chapter 1 surveys the performance models of local computer networks that make use of either ring or bus technology to connect the nodes. Chapter 2 characterizes a ring network as a collection of processing elements that are interconnected through a communications path in the form of a loop. This chapter also discusses the three basic loop access protocols: the Pierce and Newhall loops, and the distributed loop computer network. Chapter 3 deals with the possible communications systems for a network of computers. This chapter also examines the advantages and disadvantages of a bus network over other network types. This book will be of value to computer and communications engineers and designers.
