Abstract :
In this paper, we analyse the performance of an ATM switch fabric with combined-input/output buffering (C-IOB) under two different service principles for the cells at the head of line (HOL) positions of the input buffers: first come first service (FCFS)/random service (RS) for the set of HOL cells addressed to a given output port with different/same “age” (the wait time at the HOL position) and pure random service (PRS) for all HOL cells addressed to a given output port regardless of their “ages” while the queue loss (QL) transfer scheme is adopted for the interaction between the input and output buffers in the ATM switch fabric. The results obtained show that the C-IOB ATM switch fabric with PRS service policy and the QL transfer scheme is optimum among the buffering ATM switch fabrics
