traffic engineering

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.
