NLR has plans to replace its 15808s in FY 2008 and expand the foundation capacity to 160 and

128 wavelengths. As part of this upgrade NLR will introduce 40Gig capabilities.

NLR Core Services Being Used by Researchers and Educators:

Having multiple networks running over the NLR infrastructure provides researchers convenient

and broad-based access to diverse services. This same feature facilitates migration of promising

technologies into production and permits research and development to transcend individual

networking technologies. By enabling work across and on the potential interrelationships among

traditionally separate network layers--such as optical networks, switched networks, routed

networks, end-to-end transport protocols, as well as middleware and applications--NLR

enhances system-level integration of new technologies and enables increasingly critical

capabilities such as resource management and security.

Within these capabilities NLR offers the following core services.

PacketNet: IP-Based Services:

For those who need a high-quality managed nationwide backbone service with a high

bandwidth entry point at layer 3

NLR PacketNet provides nationwide IP-based services utilizing Cisco CRS-1 routers. A 10-

gigabit Ethernet connection to one of the two types of NLR PacketNet services is included as part

of most NLR memberships.

Routed IP Service

A stable, production-quality, non interruptible, AUP-free routed IP network on a 10-gigabit

Ethernet backbone that provides a range of IP-based services, including IPv4 Unicast, IPv4

Multicast, IPv6 Unicast and IPv6 Multicast. This network connects to and peers with three

international peering points: PacificWave, StarLight and Manhattan LAN (MAN LAN). Both 10-

gigabit Ethernet and one-gigabit Ethernet connections are available.

Breakable IP Service

A breakable, interruptible, AUP-free routed IP network that allows researchers to test new

technologies and services, including ones that may be disruptive to the routed network. The basic

service set is similar to the NLR PacketNet Routed IP Service, including IPv4 Unicast, IPv4

Multicast, IPv6 Unicast and IPv6 Multicast. Additional IP-based services are available upon
