ESnet partners with Corsa, REANNZ and Google in first end-to-end trans-Pacific SDN BGP multi-AS network

Corsa Technology, ESnet, and REANNZ have successfully demonstrated the first international Software Defined Networking (SDN)-only IP transit network of three Autonomous Systems (AS) managed as SDN domains.  The partners took the approach of building and testing an Internet-scale SDN solution that not only embodies the SDN vision of separation of control and data, but enables seamless integration of SDN networks with the Internet.

This first implementation passed through 3 AS domains, namely Energy Sciences Network (ESnet) at Berkeley, REANNZ at Wellington, and Google research deployment at Victoria University, Wellington (NZ).  ESnet’s node used the Corsa DP6420 640Gbps data plane as the OpenFlow hardware packet forwarder, controlled by the open-source VANDERVECKEN SDN controller stack (based on RouteFlow and Quagga).
