Software-Defined Time-Shifted IPTV Architecture for Locality-Awareness TWDM-PON

Abstract IPTV brought great potential to give network providers the capacity to expand their market value and revenue generated by increasing the number of users. Time-shifted IPTV (TS-IPTV) is one way of accomplishment through IP multicasting. Amongst the access network solutions, Ethernet passive optical network (EPON) is regarded as one of the best solutions 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 the network resource utilization. Time and wavelength division multiplexed access passive optical network (TWDM-PON) is the ultimate solution for the next generation PON (NG-PON2), in which each wavelength is shared between multiple optical network units (ONUs) by employing the time division and multiplexing access mechanism. Local-awareness based TWDM-PON allows for the higher bandwidth and optimal flexibility, fiber management, service convergence and resources sharing. In this paper, the SDN is integrated into the TWDM-PON architecture to facilitate an orchestrated multicasting time shifted IPTV through the SDN controller to control and manage the traffic. The simulation results show that the proposed architecture and mechanism improves the quality of service (QoS) requirements in terms of the mean packet delay, jitter, throughput and packet loss.
