Future Internet researches aim for an innovative Internet architecture designed with a clean slate, and Software Defined Networking (SDN) is one approach of it. OpenFlow, a typical implementation of SDN, separates the control plane and the data plane, and simple forwarding process at the data plane is done by relatively low-cost commodity switches. As is often said "deja-vu", the architecture have strong similarity with ATM LAN emulation in 1990s in some points. As the deployment of SDN goes, there have been some serious issues to be solved on security and scalability of SDN. In this presentation, we first take a look on the history of flow-based networking like ATM and MPLS, and give some thoughts on what are new and what are not among the issues of SDN. Then we introduce some recent research works including ours on security and scalability of OpenFlow.
