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...
Several nonblocking packet switching architectures have been proposed for broadband network, such as shared bus, shared memory, crossbar matrix with combined input and output queuing, etc. Their topological demerit, such as bandwidth bottleneck and insufficient processing ability to schedule I/O matching, greatly limits their ability for large scale switching routers. This paper proposes and models...
