Calculation Functions of SDN Controller for Wireless Backhaul Infrastructure

Abstract

Rapidly increasing traffic demands set up much higher requirements for data rates in the upcoming 5G mobile networks. The most promising approach for capacity enhancement is optimal reuse of network resources by deploying a large number of small cells. In order to maintain the efficiency and performance of new heterogeneous infrastructure, new approached are required to ensure optimal traffic transmission with high capacity. In this paper, we systematize mathematical methods for SDN-controller optimization. The paper contains all main computational methods ensuring the smooth operation of network applying SDN technology. Proposed approach allows to increase the efficiency of network resources utilization, provide the fault-tolerance of infrastructure and high bandwidth of the transport network.
