NATIONAL LAMBDARAIL

'National LambdaRail' is a high-speed national computer network in the United States that runs over fiber-optic lines, and is the first transcontinental Ethernet network. The name is shared by the organization of research institutions that developed the network, and, to date, plans to continue developing it. LambdaRail is similar to the Abilene Network, but LambdaRail permits deeper experimentation than Abilene does.
It is primarily oriented to aid terascale computing efforts, but is also not intended to be a service network, but to be used as a network testbed for experimentation with next-generation large-scale networks. National LambdaRail is a university-based and -owned initiative, in contrast with Abilene and Internet2, which are university-corporate sponsorships. This gives universities more control to use the network for these research projects.
Links in the network use dense wavelength-division multiplexing (DWDM), which allows up to 32 or 40 individual optical wavelengths to be used (depending on hardware configuration at each end). At present, individual wavelengths are used to carry a 10-gigabit Ethernet signal, although other systems such as SONET may also be used in the future.
Duke University's Chief Information Officer Tracy Futhey is the Chair of the LambdaRail Board of Directors. In 2004, LambdaRail completed its first main "phase".

Goals

The goals of the National LambdaRail project are:

★ To bridge the gap between leading-edge optical network research and state-of-the-art applications research;

★ To push beyond the technical and performance limitations of today’s Internet backbones;

★ To provide the growing set of major computationally-intensive science (often termed e-Science) projects, initiatives and experiments with the dedicated bandwidth, deterministic performance characteristics, and/or other advanced network capabilities they need; and

★ To enable and to rekindle the possibilities for highly creative, out-of-the-box experimentation and innovation that characterized facilities-based network research during the early years of the Internet.
