Overall Goals ( P A C I F I C L I G H T R A I
L ver.)

• Bring together leading edge RD sites,
  resources, apparatus and groups in a flexible,
  ultra-high performance 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, RD econ. dev.
  that is leveraged by ultra-high perf. ip wave
  based network fabric linking key research groups,
  sites and apparatus.

Some Discontinuities

• e2e physical connectivity!
• Persistence over enough time!
• Physical Latency Constraints
• Ultra high performance exchange points
• Measurement e2e performance
• Deterministic (e.g., Latency/Jitter control)
• Mismatched Tech. (e.g framing, channels, etc.)
• Middleware (app, authentication/security)
• Network aware/adaptive apps. OS
• Expertise/Operations (NOCs vs. Res. Groups))
• AUPs!
• Interop. exp. vs. mass .edu cmdty nets
• Goals, Plan, Mechanism for persistent core
• components cost effective provisioning of
• research nets, as and how needed

Physical

• e2e continuity ge, 10ge, ? or mix
• Last Interface
• Last Riser, Closet horizontal
• Building ltgt Campus hubs
• local loop(s) Campus/Site lt-gt POPs
• Intra Inter-regional
• hardware food chains (packets, waves )
• Rebuilding the key regional elements,
• again -(
• (in cases with owned fiber /or ? irus)
• Recalling what we knew about how hard
• this is and what the best paths/hubs are
• Hub/Ring Anchor points local build out
• For experimental/developmental nets
• where/how does it make sense to deploy

Peer Reviewed, Contract and Grant
Obligations1all gt 250 million/yr top few gt
500 million/yr
btw - LIGHTRAIL has 3 of top 5, half of top 10
(and maybe 6 of 11)
Plus major, reachable net oriented centers, labs
etc.

period causes minor variations in order and

ADDRESSING NETWORK DISCONTINUITIES

• LONG LINES
• 10 yr/IRUs
• Options for more _at_ discount
• Could buy fiber (nationally)
• METRO
• Owned Fiber Rings/Segs. in
• SEA, SF BAY, LA, SD SAC
• PROVISIONABLE DEDICATED p2p WAVES
• ESTABLISHING KEY PIECES
• FOR FLEXIBLE LONG TERM LOW COST PROVISIONING!
