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.
