An efficient and QoS-aware virtual network resource migration algorithm

In this paper, a joint reducing energy consumption and improving quality of service scheme for the migration of virtual network resources is proposed. This migration algorithm reflects the state of the virtual network resources dynamically, and the algorithm consists of two parts: Energy-efficient Module and QoS Module. Each Module is responsible for a specific function. The Energy-efficient Module is responsible for the energy consumption of servers, and the QoS Module is responsible for the quality of network service, and it can optimize the target nodes with the relative cost of migration. The efficient and QoS-Aware migration algorithm take the energy consumption and the quality of service into account. The simulation results show that the proposed algorithm can reduce energy consumption to the servers, improve the quality of experience, reduce the latency and achieve the objectives of managing of virtual network quickly and easily.
