“…Here, we describe briefly the APON architecture of the BAF system, the Medium Access Control (MAC) protocol that provides access to the shared medium, the ATM access network Testbed and results on delay distributions and 1-point CDV, see also [9], [17]. [32], [33], [43], [60], [71] and [72].…”

“…A bundlespacer is used to space the cells generated by all the connections that share a Tb since the PDA only knows the data rate requirements of a whole T¡, and not of each individual connection of the Tf,. For more specific information regarding the implementation of the counters and the used rule we refer to [17] and [43], respectively.…”

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.
