The Chinese American Networking Symposium (CANS) SDN working group has previously showcased groundbreaking demonstrations that set the stage for new interdomain SDN applications and research collaborations, and have also demonstrated a network virtualization technique to abstractly link multiple network domains, each controlled by a different organization, in a scalable, secure, agile, and open fashion. 

The CANS SDN working group collaborative project recently completed a demo at CANS2015, showcasing a collaborative SDN testbed connecting Tsinghua University/China Education and Research Network (CERNET), Beijing University of Posts and Telecommunications (BUPT), China Science and Technology Network (CSTNET), Institute of High Energy Physics (IHEP) at Chinese Academy of Sciences, Internet2, and National Energy Research Scientific Computing Center (NERSC), and how inter-domain SDN traffic engineering mechanism supports high energy physics data transmission on the testbed.

The demonstration focused on capabilities and flexibilities of programing the fine-grained rounting between SDN domains for VIP traffic identified by any IP source or destination address, or by TCP or UDP ports, which would significantly improve data transmission performance between domains under the situation of packet loss or link failure.

The group also demonstrated the enhanced version of WE-Bridge, a high performance network view exchange mechanism for multiple SDN administrative domains peering. It was first proposed and upgraded by a team led by Prof. Jun Bi at Tsinghua University.

The demonstration is an example of ongoing US-China collaborations in developing advancing SDN technology and creative applications. By highlighting how data can be transferred with advancing SDN technologies, the working group has already exemplified ways in which both high energy physics and genomic research can benefit. This ongoing commitment to facilitating cross-Pacific big scientific research will enhance the way networks and researchers connect in the future to enable innovation.
