[Abstract of the Presentation]
In order to meet the needs of inter-domain transmissions, we would like to setup a adaptive network transmission testbed based on SDN-IP with efficiency, elasticity, security, and convenience. SDN-IP is an open source application built on ONOS (Open Network Operating System) and it plays an important role for interconnection among heterogeneous networks. We exploit the L3 routing mechanism of SDN-IP for inter-domain communication for interconnecting several research sites. For end users, a local router is installed for distributing packets between SDN-IP and legacy Internet. Therefore, client hosts could transmit the packets without IP address modification. With their original IP addresses, the researchers could not only access legacy Internet but also exchange information over the SDN-IP backbone. A web-based UI is introduced for network managers to have a systematic perspective of the overall network.
