Abstract (in Japanese) (See Japanese page) 
(in English) The packet transmission of upstream in EPON can be divided into data interval and reservation interval. In reservation interval, each ONU requests transmission time to OLT by using REPORT message. The OLT receiving REPORT message calculates transmission time for each ONU. Then, each ONU can reserve the resources by receiving GATE message from OLT. The traditional method is a kind of this reservation method. However, if the RTT is large, GATE message may not arrive within a cycle time. In this situation, resource efficiency decreases because the occurrence of idle time. In order to solve this problem, IPACT has been proposed. In IPACT, a reservation interval is allocated after own ONU' data interval. However, waiting time of packets may be large depending on the arriving timing of the packets. In this paper, we propose DR-MPCP method which delay the transmission timing of the REPORT message. We model our DR-MPCP by using M/G/1 queue model and show the effectiveness of our method.
