Openflow Virtual Networking: A Flow-Based Network VirtualizationArchitecture

Abstract: Network virtualization is becoming increasingly significant as other forms of virtualization constantly evolve. The cost of deploying experimental network topologies, the strict enterprise traffic isolation requirements as well as the increasing processing power requirements for virtualized servers make virtualization a key factor in both the research sector as well as the industry, the enterprise network and the datacenter. The definition of network virtualization as well as its manifestations vary widely and depend on the requirements of the environment in which it is deployed. This works sets the foundation towards a network virtualization framework based on a flow-based controlled network protocol like Openflow.
