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.
