International Research Networking of KRLight Supporting Data-Intensive Science

Recently global collaboration research related to High Energy Physics, Astronomy, Climate Change, etc. has been gradually increased based on international research networking with hybrid networking service. For more than 10 years, GLIF Open Lightpath Exchanges (GOLE) in Global LambdaGrid Integrated Facility (GLIF) with hybrid networking technology like lightpath is critical stack to transfer big e-Science data that support global collaborative research. KRLight has become a key GOLE in Asia-pacific area bridging research network between Asian research network and North American and European research network with dynamic circuit networking facility. Today emerging technologies such as Science DMZ, Software-Defined Networking, perfSONAR and GLORIAD Insight system could be leverage networking technology to support data-intensive science with more effective and flexible. In this paper we proposed new GOLE architecture to apply these network technologies into current GOLE architecture as a key international research networking infrastructure and validated it through adaptation into KRLight.
