Abstract:

Aiming the problens at multiple users to share a multiplexing systems, in polling multi\|access communication system of threshold services, appropriate service rules must adcpted (such as reservation or interrupt\|driven). Adopt embedded markov chain theory and probability generating function method of pollers forunreachable threshold service queuing system with two different analysis methods are analyzed and the same threshold service queuing system mean queue length and average cycles of analytical results. Computer simulation results show that the simulation and theory are consistency.

Key words: polling multi-access, gated service scheme, queue length, revolving period
