OpenFlow enabled SDN Infrastructure over TEIN (OF@TEIN):
OF@TEIN is a collaboration community established to carry out OpenFlow-enabled SDN (Software-Defined Networking) Infrastructure over TEIN project. As part of the collaboration, ERNET has configured OF@TEIN testbed node. This allows researchers to perform SDN based experiments over this distributed testbed. As an initial task, we have verified the multiple access methods for accessing SDN testbed for users from different countries coming from different access networks by three access types – tunnel mode, remote desktop and virtual desktop. Based on Quality of Service (QoS) and Quality of Experience (QoE) over the measurements, the preferred access method is found to be tunnel-mode, rather than virtual desktop or remote desktop. Further developments to SDN setup was considered on access improvements and other aspects. There are various SDN experiments being carried out by the participating institutions using the OF@TEIN testbed.
