A brief description of the architecture and the benefits of Software-defined networks (SDN) is given. The different classes of applications that can be created on the basis of the SDN are discussed. Among them are policy-based routing, load balancers, cloud services management tools, security tools (ACL, firewalls and IDPS) and traffic taps from any node in the network. The application requirements for the Northbound controller API are specified. The need for high-speed duplex interface for binary data transfer is emphasized. The analysis of existing standards and implementations of Northbound SDN controller API is given. The structure of OpenStack, Floodlight and OpenDaylight APIs is analyzed. It is concluded that currently there is no standard approach and in each use case it is necessary to find an optimal solution to the problem.
