WIRELESS PROTECTION SWITCHING FOR VEDIO SERVICE IN WIRELESS-OPTICAL BROADBAND ACCESS NETWORK
This paper tackles a survivability problem of the Optical-Wireless Broadband Access Network (WOBAN). The proposed scheme introduces the ONU with wireless function (called WONU) for multiple service applications, and uses the wireless resource to protect the network from fiber failure. It establishes the wireless protect link between two WONU for the inter-ONU communication to restore the service when the last-drop fiber is cut. Moreover, to reduce the bandwidth confliction and achieve high effective bandwidth utilization, strategy by using the time-domain adaptive linear prediction and Media Delivery Index (MDI) as the reference to guarantee the QoS is embedded in the scheme. To evaluate this scheme, a WOBAN testbed is constructed. The experimental results indicate that this scheme could effectively protect the video service by using the wireless resource.
