control plane software, physicists were able to control which service (shared IP or DC Network)

their data used as files were transferred from FNAL to UNL. The highlight of this was UNL's

ability to move 48 Terabytes from FNAL to UNL in 32 hours without impacting the normal

campus traffic. This close liaison between Internet2 staff and the LHC scientific community is

just the first of many such activities Internet2 will collaborate on in the near future.

Internet2 International Activities:

Through partnerships with the world's major national and multi-national research and education

networks, Internet2 Network users have access to research, university, school, hospital and other

institutions in 88 countries and growing. As detailed above, the Internet2 IP Network and in the

coming year, the Internet2 DC Network, connect with similar networks and services in an effort

to provide Internet2 Network users the same kind of advanced networking capabilities across the

globe as they experience within the US.

Internet2 Network International Connectivity:

Offshore connectivity for the Internet2 Network is provided by Internet2's international partners,

by the National Science Foundation's International Research Network Connections program, by

the IEEAF and by Internet2 itself. Internet2 is a partner in the NSF IRNC-funded TransPAC2

project which provides connectivity to Asia; provides connectivity and management for the

IRNC-funded TransLight-StarLight link between New York and Amsterdam and is a member of

the IRNC management team. Internet2 has procured and provisioned a 10 Gbps circuit from New

York to London which is being used to provide circuit-based services between the Internet2

Network and the GÉANT2 network.

As mentioned above, Internet2 works particularly closely with GÉANT2 ESnet and CANARIE

on technical direction and development across a range of network, performance and middleware

technologies. This collaboration has already resulted in the joint development of the perfSONAR

measurement and monitoring infrastructure being adopted by the Internet2, ESnet and GÉANT2

networks. In 2007, work continued between the partners in the area of inter-domain control

protocols for connecting the networks' respective dynamically-controlled circuit services.

This group also closely coordinates on the provision and operation of trans-Atlantic

infrastructure. In particular, Internet2, ESnet and GÉANT2 are working closely together to

understand how to support the trans-Atlantic needs of the LHC community. While Tier 0 to US

Tier 1 connectivity is provided for by the LHC-OPN, much of the US Tier 1 to European Tier 2

and US Tier 2 to European Tier 1 traffic will be carried by Internet2 and GÉANT2 or ESnet and

GÉANT2 interconnections.

Internet2 Efforts to Stimulate Research and Education Network

Developments in currently undeserved countries:

Internet2 supports its members' needs to get access to instruments, data and collaborators in

countries currently underserved by research and education network infrastructure through a

variety of activities. Ana Preston of Internet2 recently presented at the ICFA Digital Divide

conference in October of 2007 on the range of these activities.1

The Internet2 Special Interest Group (SIG) on Emerging Research and Education Networks2

continues to convene the US and international community to focus on particular regions of the
