Virtualized network isolation using Software Defined Networks

The increasing interest in Cloud Computing has brought new demands to providers of “Infrastructure-as-a-service” solutions. To host a large number of clients in the same datacenter, they require multi-tenant networks that can guarantee traffic isolation and scalability, with low costs. This paper describes a solution for this problem using Software Defined Networks (SDN). With SDN, we can program the virtual switches at the physical servers so as to meet all those requirements, without demanding special hardware in the network.
