Effects of the Transition
  • In August 2001, we notified people that our
    Sprint circuits would be going away on or after
    September 1, 2001
  • All of them were officially disconnected mid
    January 2002
  • NREN peering in Chicago will be down for about 2
    months while we are waiting for our new Qwest
    circuits
  • Glenn Research Center (GRC) will experience a
    similar disruption in service
  • Langley Research Center (LRC) connectivity is
    postponed indefinitely due to funding constraints

NREN / NPN Relationship
  • NREN Description
  • The NASA Research and Education Network (NREN) is
    part of the Computing, Information and
    Communications Technologies (CICT) Program
    managed at NASA Ames Research Center
  • Infuses emerging network technologies into NASA
    mission-critical applications
  • Coordinate technology transfer to NPN
  • NREN serves several purposes
  • Experiment with network hardware and software
    that provides leading edge capabilities
  • Prototype applications enabling NASA missions
    that cannot be supported by todays commodity
    Internet
  • Demonstrate emerging technologies and
    applications

9
NREN / NPN Relationship
  • NPN Description
  • The NASA Prototype Network (NPN) is a network
    being developed as part of the NASA Integrated
    Services Network (NISN)
  • NPN will serve as a bridge between the NASA
    Research and Education Network (NREN) and NASAs
    operational network services
  • Sufficiently stable infrastructure to
    appropriately transition leading edge NASA
    applications to NISN operations
  • NPN serves several purposes
  • Foster the transition of application and
    protocols from NREN to the NASA operational
    network
  • Investigate operational impacts such as cost,
    technology, support and performance
  • Drive the NASA operational network configuration

10
NREN / NPN Relationship
  • Protocol and technology research shall relate to
    NASA communications technical issues and be
    geared to improve operational network services
  • NREN and NPN serve as the NASA WAN testbed and
    thus will not compete with NASA operational
    network services

NREN-NPN Initial Configuration
  • Point-to-point PVCs
  • Fully meshed
  • 8 NREN routers 5 NPN routers
  • Shared backbone PVPs between regional core hubs
  • East region core hub (Washington DC)
  • HQ, GSFC, NGIX-E
  • North region core hub (Chicago, IL)
  • NGIX-Chi, GRC
  • West region core hub (Sunnyvale, CA)
  • ARC, JPL, NGIX-W
  • Direct PVPs to MSFC from east and west core hubs

14
NREN-NPN Initial Configuration
  • Traffic parameters between 3 regional hubs
  • OC-12 between east and west hubs
  • OC-3 to and from the north hub
  • VBRnrt
  • SCR 150 Mb/s, PCR 600 Mb/s
  • Traffic contract parameters to MSFC from core
    hubs

  • VBRnrt
  • SCR 37.5 Mb/s, PCR 150 Mb/s

15
Peering Plans
  • NGIX West Status (OC-12)
  • Currently peering with Abilene, DREN, ESnet,
    NISN
  • USGS Planned
  • NGIX East Status (OC-12)
  • Currently sharing a GSFC connection, soon to be
    transitioned to a NREN only connection
  • No private peering established
  • Planned Peering Abilene, DREN, NISN, USGS

16
Peering Plans

  • I-WIRE Gigabit Ethernet circuit from Qwest Hub
    (455 North CityFront Plaza) to StarLIGHT (710
    North Lakeshore Drive)

  • Planned Peering TRANSPAC, Abilene, NORDUNET,
    SURFnet, AMPATH, Argonne, Northwestern University

19
Passive Monitoring PCMon
Traffic flow bandwidth
  • Development and installation of Quality of
    Service and multicast data collection tool
    (PCMon) that
  • Enables detailed analysis of individual traffic
    flows
  • Enables determination of the effectiveness of
    assigning preferential treatment to specified
    traffic flows

20
Passive Monitoring PCMon
  • The measurement PC passively captures signal from
    optical splitter
  • Summarized data is sent out-of-band to the
    management and collection platform
  • Supports OC3 ATM upgraded to OC12 and POS using
    Endace/University of Waikato DAG cards
