Analysis of Mobile Communication Network Architecture Based on SDN

With the development of mobile network and the continuous improvement of network speed, the pressure of network traffic is becoming more and more prominent. In this context, the design of the fifth generation (5G) communication networks has become one of the key issues considered by operators. This paper studies a new open wireless access network architecture based on Software Defined Network (SDN) and Reservoir Computing (RC). On this basis, a scheme of air interface control and data separation in mobile communication network is designed. Firstly, through the advantage of the SDN, storage analysis of the energy cost of the underlying network equipment, the cost of virtual network resources and the average load of CPU are unified managed. Secondly, an adequate adaptive reservoir pool Echo State Network (ARP-ESN) model is proposed to enhance users' traffic predicting. With the combination of global view resource state and precisely traffic predicting, the dynamic configuration of network resources under the specific business function chain is realized, so as to improve the utilization of the whole basic network resources. The simulation verifies the reliability and effectiveness of the algorithm. It can realize the rapid deployment of 5G mobile communication network and the flexible management and control of virtual network functional units, so as to improve the overall utilization of network resources.
