Performance of shared medium access protocols for ATM traffic concentration

Abstract

The paper analyses the problem of Medium Access Control in a Passive Optical Network, used to concentrate ATM user traffic. Feasible solutions for the problem are investigated and two protocols to resolve contention on the shared medium are presented, the single cell and the multiple cell frame based. The performance of the two protocols is evaluated, obtaining indications about the transfer delay introduced by the protocols and the amount of buffering needed at the user side.
