Abstract

An improved version of the Static-Threshold-Limited On-Demand Guaranteed Service Timed-Token (STOGSTT) Media Access Control (MAC) protocol for channel capacity allocation to the asynchronous trac in Multiservice Local Area Network (MLANs) was developed and analyzed. TLODGSTT protocol uses static value of threshold bandwidth to allocate available bandwidth to the asynchronous trac, as such, the throughput of STLODGSTT protocol drops signi cantly under non-uniform heavy load of asynchronous trac. The DTLTT protocol dynamically adjusts the threshold bandwidth in response to the variations in the load distribution of the asynchronous trac. In view of this dynamic mechanism, under various load distributions of the asynchronous trac, the DTLTT protocol maintains higher throughput than the STLODGSTT protocol. The improvement is demonstrated through analytical computations and simulation results.
