Development of educational resource datacenters based on software defined networks

This paper describes application features of software defined networks (SDN) to build educational resource datacenters (ERD), which are intended for shared remote access to paid software for students from different educational institutions. We proposed a virtual classroom scheduling algorithm based on simulated annealing heuristic, a genetic algorithm for traffic routing and providing QoS for data flows. We have implemented these algorithms using C++ and partially tested them on the ERD simulator, which is still under development. Preliminary experimental studies have demonstrated their efficiency. The main feature of the proposed solutions is an interrelation between the virtual classroom scheduling algorithm and the algorithm for proactive routing and providing QoS parameters. The first algorithm reports the information about an assignment of virtual classroom's machines to the physical servers and its communication pattern to the second algorithm.
