摘要：

针对融合网络局部过载及网络设备故障造成大量业务中断问题，提出一种适用于光纤无线融合网络的虚拟化多路径可靠传输机制．通过建立虚拟化分层模型，利用虚拟化网络资源集中管理及网络全局视角优势，采用多路径并行传输机制，设计了故障后恢复方案以保障网络可靠传输．结果表明，所提机制性能优于全备份及共享备份算法，在实现网络负载均衡、提高资源利用率的同时最小化备份资源，保证了网络的可靠性．

Abstract:

For the problem that the localized overload of the integrated networks and the equipment failure will make the business interruption, a virtualized multi path reliable transmission mechanism for the integrated fiber-wireless access networks is proposed. By establishing the virtualized hierarchical model and adopting the centralized management of resources of the virtualized network and the network overall visual superiority, we use the multi-path parallel transmission mechanism to design a recovery scheme after a breakdown so as to ensure the reliable transmission of the network. The results show that the performance of the proposed algorithm is better than the full backup and shared backup algorithm. In addition, the proposed algorithm can ensure the network reliability while the network load balancing is achieved and the resource utilization rate is improved.

Key words: integrated fiber-wireless access networks, network virtualization, reliability, multipath
