摘要

光纤—无线融合（fiber-wireless

FiWi）宽带接入网的出现不仅为随时随地的灵活宽带接入提供了新的技术参考，同时也为可生存宽带接入网的低成本设计增加了研究契机。研究了可生存FiWi接入网的网络规划问题，提出一种基于无线重路由保护的可生存网络规划方法。当任意光纤链路断裂时，失效的光网络单元可通过无线重路由将业务转移到其他可用的光网络单元承载。重点解决了无线路由器部署、备份射频接口配置及光网络单元容量分配的联合优化问题，目标是通过最小化网络部署成本实现业务的完全保护。采用整数线性规划方法获得了小规模网络规划问题的最优解，同时提出了适用于大规模网络规划问题的启发式算法。仿真结果证实了所提方法在降低网络部署成本方面的有效性。

Abstract

The emerging fiber-wireless（FiWi）broadband access network provides not only the new technological references for flexible broadband access anywhere and anytime

but also the research opportunities for the cost-efficient design of survivable broadband access network.The study of survivable FiWi access network planning was focused on

and an approach of survivable network planning based on wireless-rerouting protection was proposed.When any fiber link cuts

the failed optical network unit（ONU）can transfer its traffic into other normal ONUs.Solving the joint optimization problem of wireless routers placement

backup radios configuration and ONU capacity allocation was put more importance on

aiming to fully protect all traffic with the minimum deployment cost.The method of integer linear programming was employed to obtain the optimal solution for small-scale network planning.The heuristic algorithm was also proposed for the large-scale network planning.Simulation results demonstrate the effectiveness of the proposed approach in reducing network deployment cost.
