Software-defined network decouples control plane from data plane, and significantly facilitates the speed of control plane innovation and enhances network control flexibility at run time. Most existing efforts on SDN revolve around OpenFlow switches, which require a wholesale investment in the network infrastructure. Ethernet-based SDN, which ITRI has been working on for over 4 years, applies the same SDN design principles to commodity Ethernet switches, and provides similar benefits in network control flexibility. Most importantly, Ethernet-based SDN enables users to preserve the enormous investments in their legacy network infrastructure. Recently, we have been exploring the idea of hybrid SDN, in which both Ethernet and OpenFlow switches in a network are controlled by the same central controller. We are able to show that a particular form of hybrid SDN, ECOE, is as powerful as pure-OpenFlow network with respect to major SDN applications such as network virtualization and dynamic traffic engineering.
