Internetworking Issues: Bridging Local Area Networks Using Systems of Communicating Machines.

摘要

The evolution in network and communication technology has led to the need to interconnect individual computer networks. Network designers are faced with the heterogeneity of networks just as they were previously faced with the heterogeneity of computers within a single network. Many issues must be considered in interconnecting various types of networks. This thesis identifies some of these issues as they pertain to the interconnection of two IEEE standards for Local Area Networks, Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Token ring. It further discusses a major concern regarding bridging a simplified version of the CSMA/CD and Token Ring protocol using a system of communicating machines. The model employs a combination of finite state machines and variables in the specification of each machine. Communication between machines is accomplished through shared variables. The thesis concludes by summarizing the issues related to the bridging two Local Area Networks, CSMA/CD and Token Ring, using a system of communicating machines. The advantage this model has over other formal description techniques is briefly described. Keywords: Computer networks, Internetworking, Communicating machine systems. Theses. (edc)
