Abstract

The rapidly evolving field of local network technology hasproduced a steady stream of local network products in recent years.The IEEE 802 standards that are now taking shape, because of theircomplexity, do little to narrow the range of alternative technicalapproaches and at the same time encourage more vendors into thefield. The purpose of this paper is to present a systematic,organized overview of the alternative architectures for and designapproaches to local networks.The key elements that determine the cost and performance of alocal network are its topology, transmission medium, and mediumaccess control protocol. Transmission media include twisted pair,baseband and broadband coaxial cable, and optical fiber. Topologiesinclude bus, tree, and ring. Medium access control protocolsinclude CSMA/CD, token bus, token ring, register insertion, andslotted ring. Each of these areas is examined in detail,comparisons are drawn between competing technologies, and thecurrent status of standards is reported.
