In this paper we analyzed suitability of different routing algorithms for establishing bandwidth-delay constrained traffic tunnels in SDN backbone networks. Bandwidth rejection ratio was used as indicator of algorithm's ability to efficiently utilize network resources. Through set of simulations on two real backbone topologies we showed that network topology can affect algorithm's performance, and...
Cloud based datacenters will be most suitable candidates for future software defined networking. The QoS requirements for shared data centers, hosting diverse applications could be successfully achieved through SDN architecture. This paper provides an extension of our previously proposed scheme QAMO that was aimed at achieving tangible QoS in datacenters through controlling bandwidth reservation in...
The paper describes the testbed to determine the effectiveness of an approach to build network storage using Software-Defined networks (SDN) OpenFlow. It is assumed that main protocol to SAN is iSCSI over local area network. Prototyping tools for managing network resources and data flows on the basis of SDN and testing environments based on Free and Open Source software. We describe experiments with...
