摘要：In this paper, we propose a P2P file sharing architecture
in TWDMA-PON with software-defined network (SDN) system to
reduce inter- and intra-traffic to improve the quality of service
(QoS). In addition, the proposed scheme employs colorless ONUs
(tunable transceivers) to simplify the network operation, reduce
installation cost, and enable easier maintenance. Moreover, we
implement an integrated SDN with OpenFlow protocol to
separate the control and data planes, enabling flexible and
centralized control of the P2P intra-traffic. Simulation results
demonstrate that our proposed scheme can realize QoS
improvements up to 21% in the in terms of the packet delay,
23.9% in jitter, 13% in throughput, and reduce traffic-dropping
up to 58% in scenario 6 (5:40:44:11) for the 1.5 ms cycle time.
