RE Networking in USA

• 1969-90--ARPANET (Milnet split off in 83)
• 1981-96--BITNET/CREN
• 1981-91ish--CSNET (CSnet merged with BITNET into
  CREN)
• 1986-95ishNSFnet
• 1995-2001ish--vBNS
• 1996-97---Internet2/Abilene
• 1997-CENIC/CalREN (California)
• 2002-03-CENIC deploys statewide fiber backbone
• 2003-NLR NLR created for deploy national fiber
  backbone

CENIC Mission and Goals

• Mission
• to develop, deploy and operate leading edge
  network-based services and to facilitate and
  coordinate their use for the RESEARCH and
  education community to advance learning and
  innovation
• Goals
• Provide competitive advantage in global
  marketplace to education and RESEARCH communities
• Provide opportunities for innovation in teaching,
  learning and RESEARCH through use of the network.

4
Why A Fiber Infrastructure?

• Cost effective
• Customize services to meet variety of needs
  instead of one size fits all
• Ability to provision services quickly to meet
  specialized needs - i.e., iGRID

5
CENIC/CalREN Tiers of Service

• Network Development and Evolution
• For California Research and Education Community

Internet2 Services

• Advanced network applications enables
  collaboration among people and provide
  interactive access to information and resources
  in ways not possible on today's commercial
  Internet.
• New network capabilities i.e., Quality of
  Service, multicasting, and IPv6 are being
  aggressively tested and deployed in the networks
  used by Internet2 members.
• Middleware behind-the-scenes software, is
  providing security, directories and other
  services required by advanced network
  applications.
• High-performance networks linking the campuses
  and laboratories of over 200 Internet member
  institutions.

12
National LambdaRail Mission

• To advance the research, clinical and educational
  goals of members and other institutions by
  establishing and maintaining a nationwide
  advanced network infrastructure.

National LambdaRail (NLR) Goals

• Support experimental and production networks
• Foster networking research
• Promote next-generation applications
• Facilitate interconnectivity among
  high-performance research and education networks

15
Internet2 and NLR-to Merge or Not to Merge

• Questions regarding the need for two different
  national education and research networking
  organizations
• CENICs interests are
• to obtain cost effective national transit for CA
  educational institutions,
• to obtain services similar to those of the CENIC
  pyramid but on a national basis,
• exploit use of fiber network NLR has acquired.

Communities Served by CENIC, Internet2 and NLR

• Network Researchers
• Science ResearchersBig Applications
• Educators---Teaching-Learning Applications
• Supercomputing continues to be a key driver!

20
Changes in RE Impacting Networking Needs

• Growing urgency for new network technologies
• Increased collaboration worldwide onBig Science
  projects
• Exponential growth in size of data sets being
  accessed
• Need for multiple dedicated/private research
  networks
• iGRID last month demonstrated many examples of
  high-end and lightpath network applications

Potential Network Research ProjectVirtualized
Testbed for Network Research

• Provide multiple heterogeneous virtual networks
  on a common substrate.
• Engage broad networking research community.
• Bridge gap between cutting-edge research and
  production usage.
• Proposed by
• Tom Anderson, University of Washington
• Larry Peterson, Princeton University
• Scott Shenker, UC Berkeley
• Jon Turner, Washington University in St. Louis

26
Planning for Future CENIC Net Services

• CENIC Board Subcommittee defining future service
  needs
• John Dundas, CalTech Chair
• Larry Smarr, UCSD/CalIT2, Vice Chair
• John Silvester, USC
• Ron Johnson, University of Washington
• Mike Scott, UC Irvine
• Jim Davis, UCLA
• Greg Hidley, UCSD/CalIT2
• Jim Dolgonas, CENIC
• Dave Reese, CENIC

27
Potential List of Future CENIC Net Services

• End to end optical lambda/wave services
• Ends are labs/desktops at campuses
• Cross national and international network
  boundaries
• Ability to obtain these for short periods of
  times on short notice (user switched??)
• End to end switched ethernet services (same as
  above)
• New-experimental routed services (layer 3, to
  complement experimental routed services of NLR)

28
Enhancement of CalREN or Buildout of XD

• CENIC issues to address
• CENIC needs input from campuses (researchers) on
  needs
• If dedicated networks (Lambdas) needed by
  researchers, demarc (handoff) between CENIC and
  campus needs to be made more flexible
• Funding is required for high end (XD layer) needs
• End to end performance issues require campus and
  CENIC partnership to address
