Abstract: | An extended IEEE 802.5 protocol suitable for transmitting time constrained messages in real time token ring fibre optic local area networks has been proposed and analysed for its performance subsequently. It differs from the traditional token ring protocols as time constraints of messages are incorporated explicitly. In this protocol, the laxities of messages are mapped into priorities. The message with the highest priority is transmitted first, thus, resulting in a delay dependent priority queue at a node of the network with linearly increasing priority function. So, this extended IEEE 802.5 protocol approximates the minimum-laxity-first transmission policy |
