Performance Analysis C)f a Protocol for Real Time Token Ring Folan

An artended IEEE 802.5 protocol suitable for transmitting time consh-dm'ed messages in real time token ring fibre optic local area networks has been proposed and analysed for its performance subsequently. It differs from the tmhtional token ring protocols as time COIlstraints of messages are i n v t e d explicitly. In this protocol, the laxities of messages are mapped into priorities. The message with the w e s t priority is transmitted fk t , thus, resulting in a delay dependent priority queue at a node of the network with linearly i n priority fimction so, this extended IEEE 802.5 protocol w the minimtrm-laxity-first transrmsslon policy.
