Fiber-wireless (FiWi) access networks, which are a combination of fiber networks and wireless networks, have the advantages of both networks, such as high bandwidth, high security, low cost, and flexible access. However, with the increasing need for bandwidth and types of service from users, FiWi networks are still relatively incapable and ossified. To alleviate bandwidth tension and facilitate new service deployment, we attempt to apply network virtualization in FiWi networks, in which the network’s control plane and data plane are separated from each other. Based on a previously proposed hierarchical model and service model for FiWi network virtualization, the process of service implementation is described. The performances of the fiWi access networks applying network virtualization are analyzed in detail, including bandwidth for links, throughput for nodes, and multipath flow transmission. Simulation results show that the FiWi network with virtualization is superior to that without.


研究目的:融合了光纤网络和无线网络的光与无线接入网(fiber-wireless access network)同时拥有两种网络的优点。但是,相对于用户不断增长的带宽和业务需求,光与无线接入网仍相对落后和僵化。为了缓解带宽紧张,加速新业务部署,我们尝试在光与无线接入网中应用网络虚拟化。本文提出了光与无线接入网虚拟化中的业务实现流程,分析探讨了应用网络虚拟化带来的网络性能提升。
