increase its capacity easily and flexibly by utilizing additional 10Gbps wavelengths on any path

of the Internet2 Network infrastructure.

Figure 4: Internet2 IP Network

Any Internet2 member organization may connect to the Internet2 IP Network through an

Internet2 Connector. Internet2 Members may also sponsor non-member organizations and

statewide education networks to use the Internet2 IP Network.

The Internet2 IP Network peers with the major US national research networks, including ESnet4,

DREN, NISN and NREN. The Internet2 IP Network has direct peering with 24 non-US networks

and via transit reaches over 88 National Research and Education Networks in Africa, Asia,

Europe and Latin America and the Middle East. The Internet2 IP Network, in turn, provides

transit between any non-US networks.

Internet2 Dynamic Circuit (DC) Network:

The Internet2 DC Network is a completely new network service that realizes the community's

vision of hybrid (IP and dynamic circuit) networking. Currently operated as a persistent service,

the Internet2 Dynamic Circuit (DC) Network uses community-developed, standards-based

technologies and protocols to provide on-demand dedicated optical paths between endpoints.

Services enabled by the DC Network include short-term, point-to-point circuits, setup by the

requestor or application in standard SONET bandwidth increments up to 10 Gbps. The DC

Network is based upon the connections into the Ciena CoreDirectors and use of newly developed

control plane software. See Figure 5 for a map of the Internet2 DC Network.
