DR-MPCP: Delayed REPORT message for multipoint control protocol in EPON

The packet transmission of upstream in Ethernet Passive Optical Network (EPON) can be divided into data interval and reservation interval. Interleaved polling with adaptive cycle time (IPACT) is a popular polling scheme of EPON. In IPACT, a reservation interval is allocated after own network termination unit´s data interval. However, the waiting time of packets (= the packet delay) may be large depending on the arriving timing of the packets. In order to reduce the mean packet delay, we propose a novel reservation interval allocation method which delay the transmission timing of the request message for reservation. For evaluating the effectiveness of our proposed method, we use M/G/1 queue model to analyze the behavior of the method.
