OpenFlow

In this paper are proposed the number of solutions for improvement of control plane in software-defined networks. One of the main problems that arise when designing and implementing new network is the problem of developing efficient and optimal network control system. SDN technology has control plane and data forwarding plane separated from each other.

In this paper is proposed a solution to the problem of low efficiency of bandwidth usage of physical channels. In the beginning adducted a necessity to implement proposed solutions at transport network. The main problem of transport networks is low level of utilization of optical channels resources. As a result it is often very expensive to exploit such a network due to high capital and operational costs. The method of distributed multi-flow traffic engineering in software-defined networks based on means and mechanisms of flow processing by Openflow switches has been developed.
