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 differentiated services (DiffServ) model relies on the per hop behavior (PHB) in each network device to treat packets differently based on packet headerspsila DSCP (DiffServ code point). For each DiffServ compliant router, the scheduling algorithm is critical in implementing PHBs, according to which packets are forwarded. In this paper, we propose the parallel maximum urgency first (PMUF) scheduling...
