Abstract
This paper investigates the inherent timing properties
of the timed-token medium access control (MAC) protocol
necessary to guarantee synchronous message deadlines in a timed
token ring network such as, fiber distributed data interface
(FDDI), where the timed-token MAC protocol is employed. As a
result, an exact upper bound, tighter than previously published,
on the elapse time between any number of successive token
arrivals at a particular node has been derived. Based on the
exact protocol timing property, an optimal synchronous bandwidth
allocation (SBA) scheme named enhanced MCA (EMCA)
for guaranteeing synchronous messages with deadlines equal to
periods in length is proposed. Thm scheme is an enhancement on
the previously publiibed MCA scheme.
