Abstract
With the continuous advancement of smart grid construction, the flexible and ever-changing power business has higher requirements for communication networks. In this study, in order to improve the reliability of communication networks, an end-to-end network slicing backup algorithm was proposed. Firstly, the important nodes in the current network slicing were backed up to obtain a backup virtual network. The criticality of the original virtual nodes was calculated based on resources and network topology, and the deployment of highly critical virtual nodes and their corresponding backup nodes were prioritized. Then, the candidate set for each virtual node was obtained, and virtual nodes and virtual links were mapped using the Dijkstra algorithm. This algorithm backed up important nodes in the virtual network before mapping them. A link connection was made between the original virtual node and its corresponding backup virtual node, which was used to transmit its resources and information to the backup node after the original virtual node fails. The simulation results show that the algorithm effectively improves the reliability in different network scale environments.
