Future practical implementation of secure quantum communication technology in a multiuser network environment would require automatic monitoring of the optical link condition and quantum system parameters, along with adjusting them in real time according to protocol restrictions. We demonstrate how software-defined networking (SDN) paradigm can be used for addressing this problem on the example of a subcarrier wave quantum communication system, which is promising for network applications. We propose a novel approach to dynamic quantum network routing and communication security based on SDN OpenFlow protocol. SDN-operated dynamic switching between different data encryption methods, quantum or classic, will enable to organize virtual encoding channels with an ability to set the required Quality of Service level for security/bandwidth. These developments will further increase the feasibility of quantum technologies from the network perspective and contribute to bringing them to industrial scale.

Published in Digital scientific magazine «Modern problems of science and education» Abstract: A briefdescription of the main trends in the development of Software-defined networks (SDN) is given. We compare the advantages and disadvantages of the most popular approaches: end-to-end OpenFlow and virtual network overlays. We are describing existing SDN solutions. Among them, architectural and hardware preferences of Juniper Networks, the Virtualized Services Platform (VSP) from Nuage Networks, an integrated VMware/Nicira solution NSX and Windows Network Virtualization from Microsoft. Most of them tend to implement SDN on the existing infrastructure without having to replace network equipment, maintaining existing services. Main functions of the systems are implemented in software virtual switches that are directly managed by the hypervisor. It is concluded that at the present time OpenFlow has practical application only as a control protocol for virtual switches and most solutions are based on the virtual network overlays.
