A Performance Analysis of Buffered DQDB Network with Request Arrival Process Depending on Its Request Counter Value and Its Location on the Buses

摘要

The location of stations on the buses can not be ignored in the analysis of the DQDB protocol, especially when traffic load is heavy. In this paper, we propose a new method to model the DQDB (Distributed Queue Dual Bus) protocol by assuming that the request arrival process depends on both the value of the request counter and the location of a station on the buses. By taking these dependences, we can catch the real behav- ior of the DQDB stations, which is locationally dependent and unfair under heavy load traffic.
