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
• OC-3
• VBRnrt

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

• NGIX Chicago Status (OC-3)
• Plans to connect to StarLIGHT in April 2002
• I-WIRE Gigabit Ethernet circuit from Qwest Hub
  (455 North CityFront Plaza) to StarLIGHT (710
  North Lakeshore Drive)
• Source for international peering
• 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

• Exploring Qwest Total Care
• Connect more centers
• GRC, MSFC
• Re-establish connectivity in Chicago
• QoS Testing
• Migrating from ATM to POS once it is cost
  effective
