Enabling SDN in Hybrid Xhaul-TWDM-PON Networks for Interactive Video Applications

Nowadays, the latest age of immersive media technologies such as interactive video application, virtual reality or 3D television, multiplayer online gaming, which has brought users new technological perspectives, has contributed to a significant revolution of the broadcast environment in coming years. And most of these bandwidths will be created by mobile users. It is therefore expected that the Time-Wavelength- Division-Multiplexing Passive Optical Network (TWDM-PON) would help the integration of wired and wireless networks resulting from hybrid optical-wireless architecture, which is the best choice for next-generation architecture design. In this paper, we proposed the Hybrid Xhaul-TWDM-PON networks with SD local cache management for interactive video applications mechanisms. OpenFlow controller is also the use of the smart local cache with QoS-conscious mechanism, to locally track and store the most common video at S-OLT, to lower end- user latency and increase end-user QoE. Simulation results shows that the proposed mechanism can improve the overall system performance in terms of mean packet delay, packet dropping and bandwidth efficiency.
