Abstract
Fiber-Wireless (FiWi) access network is a promising broadband access network. Taking its heterogeneous structure into consideration, the paper introduces the Software Defined Networks (SDN) into FiWi access network. Survivability is an important issue in FiWi access network. Once there is a single fiber fails, many high-rate traffic flows may loss. A failure detection scheme is proposed for one distribution fiber fault in the new architecture. For the affected data flows recovery, we focus on the bandwidth allocation scheme for different priorities queues to meet the QoS. The simulation results show that the proposed scheme can maintain the QoS performance in terms of delay, loss rate and network throughput. The survivability is improved efficiently.
