A distributed channel-sense non-preemptive static priority ring for local area computer networks and its performance
Isaac Ghansah · 1987
In a Local Area Computer Network (LAN), a set of independent distributed users compete for access to a single, shared resource which is the communication channel. Thus there arises the need for rules to control access to the communication channel;Such rules are generally called protocols or more specifically, Medium Access Control (MAC) procedures;This dissertation describes one such MAC procedure called the Distributed Channel-Sense Priority Ring (DCPR) which has been implemented on a ring topology. A formal protocol specification language called SAN (State Architecture Notation) is used for such a description;A performance model of DCPR is presented. Studies of it and suggestions of an improved DCPR protocol called IDCPR is provided;Performance comparison of DCPR and IDCPR with well-known medium access control protocols is further provided.
