Abstract :
In first mile networks, traffic may belong to different priority classes, which have different levels of delivery urgency. In this paper we introduce a mechanism for network wide prioritized access in IEEE 802.3ah EPONs which use the MPCP protocol. The mechanism is simple, and is compatible with the standard MPCP protocol. The basic ONU protocol does not have to be changed, while the protocol used at the OLT side requires little, and simple changes. Several objectives of priority mechanisms are stated, and the developed mechanism is shown to satisfy the stated objectives through a simulation study. The proposed protocol can be used with any dynamic bandwidth algorithm for EPONs.
