Overall Goals ( P A C I F I C L I G H T R A I L ver.) Bring together leading edge R&D sites, resources, apparatus and groups in a flexible, ultra-high performance experimental ip and p2p wave and fiber based network fabric that can accelerate: progress in science and medicine; the development of Grid infrastructure and bleeding edge applications, architectures and content; and, the next generations network technology and networked apparatus etc. Accelerate progress in science, R&D & econ. dev. that is leveraged by ultra-high perf. ip & wave based experimental network fabric linking key research groups, sites and apparatus. draft 12/05/01

What to do? Program to establish facilities for responsively provisioning customized and/or dedicated ‘experimental’ end-to-end networks [including extended backplanes] and networking capabilities providing: 1) Custom networks dedicated to serving specific needs of projects, programs, experiments and apparatus etc.; and, 2) Networks which are themselves experimental exercises. [i.e. be facilities that can provision (& instrument) any arbitrary networks as needed] + Lessons Successes (e.g., ARPAnet, early NSFnet), & ‘Failures’ 12/5/01
