Communication network node fault recovery strategy under network function virtualization

Abstract

In order to improve the output stability of communication network nodes, a fault recovery strategy of communication network nodes based on channel equalization scheduling under the virtualization of network functions is proposed. The channel model of wireless communication network under the condition of virtual network function is established, and the communication channel equalization is designed by Porter interval equalization scheduling method, Function virtualization, the phase shift of output channel of each node is obtained, and the impulse response of analog channel under the condition of network function virtualization is obtained. The simulation results show that this method has good adaptability to the fault recovery of communication network nodes, reduces the output error rate of communication network, and improves the transmission fidelity of communication network nodes.
