Time-shifted IPTV (TS-IPTV) is one way of implementing that, through IP multicasting. Ethernet passive optical network (EPON) is regarded the best solution due to its high bandwidth provision, low operation and maintenance cost. Software-defined networking (SDN) separates the network control plane from the data-forwarding plane with the promise to dramatically improve network resource utilization. Local-awareness based TWDMA-PON allows for higher bandwidth and optimal flexibility, fiber management, service convergence and resources sharing. In this paper, we propose to integrate SDN into the TWDMA-PON architecture to facilitate an orchestrated multicasting TS-IPTV and using the SDN controller to control and manage the traffic. Simulation results show that the proposed architecture and mechanism improves QoS requirements in terms of mean packet delay, jitter, throughput and packet loss.
