Overview of Global R&ENetworking Direction
• The international research and education community hasmounted significant efforts to develop a new generation ofnetworking capabilities that have at the core infrastructureowned/controlled, provisioned and managed by the R&Ecommunity:– all-optical with multiple point-to-point wavelengths, currently at
the 10Ge level.– Services provisioned across these backbones are multi-layer,
multi-service in nature, including Layer 1, 2 and 3 services.– Efforts include “control plane” issues of how you manage and
monitor provision of “hybrid” services across multiple servicelayers, across multiple network domains, often on an internationalbasis.

Needs of Global R&E Collaborations areDriving the Networking Development
• The need for such new services is driven by theapplications community - the research community that istypically a globally-distributed collaboration.
• U.S. “CyberInfrastructure” one such effort focused on theinfrastructural needs, and is now a new program office ofthe National Science Foundation.
• New research collaborations include the need to movemassive amounts of data in real time, control expensiveand unique equipment, etc. Example projects include:– the high energy physics community’s Large Halon Collider
(LHC) project coming on line next year at CERN in Geneva, theextended very long baseline interferometry (eVLBI) radioastronomy project with antenna arrays located around the world.
– The eVLBI (very long base-line interferrometry) internationalcollaboration in radio astronomony

Overview of Global R&ENetworking Direction
• This tutorial will provide some insight into thesedevelopments and the driving motivations – and potentialfuture developments and possible implications for thesubmarine cable industry.
• The presentation will include overviews of GLIF andDRAGON objectives and technology developments, andother similar, related projects and initiatives.
• One goal of this tutorial is to stimulate discussion of areasof needed development/collaboration regarding submarinesystems technology - so that these important links betweenglobal R&E communities do not become the “disconnect”.

NSF Funding for InternationalResearch Network Connections
(IRNC)• NSF funding new links from U.S. to International R&E
Networks(2.5 to 10 Gbps “lambdas”)– To Europe– To Asia-Pacific– To South America– To China and Russia– Nothing to African yet
• Purpose is to support US researchers - in their research andtheir international collaborations
