NASA Research and Engineering Network (NREN)
Overview
NREN Target September 2006
  • NREN Goal
  • Provide a wide area, high-speed network for large
    data distribution and real-time interactive
    applications
  • Provide access to NASA engineering and research
    communities

StarLight

GSFC
NREN WAN
ARC
LRC
JPL
MSFC
10 Gigabit Ethernet
JSC
OC-3 POS
Primary Focus Providing end-to-end distributed
data delivery to/from Columbia computing
facilities
  • NREN is currently transitioning from ATM to
    lambda services
  • ARC link to JPL is up
  • NLR contract was signed 8/31/05

3
Overview - Sample Application
  • Global atmospheric modeling
  • Real-time prediction of Atlantic tropical
    cyclones and other weather anomalies
  • GSFC model runs on Columbia terabyte data files
    are stored at GSFC
  • Application requires real-time access to Columbia

4
Optical Services
  • NLR will enable NASA to use lambda services
  • Private lambda ring between NLR nodes
  • Local loops to NASA end sites are either
  • Dark fiber
  • Managed services - 10 GigE lambdas
  • NREN upgrades currently underway
  • 2005 Shared 1 Gbps connection between ARC-JPL
  • 2005 10 Gbps connection between ARC-GSFC
  • 2006-2008 More connections over the 2-3 years
  • Enhancements under consideration
  • 2006 InfiniBand over WAN
  • 2006 Flexible lambda selection
  • 2007 Full 10 Gbps intrusion detection
  • 2007-2010 Dynamic light-path allocation

5
Optical Technologies
  • NREN has chosen Ciscos 6500 as a core connection
    platform for L2/L3 connectivity with LAN PHY
    hand-offs
  • NLR depends on Cisco for its optical network
    switching platforms ONS 15808 and 15454
  • NASA will be connected to various RONs, which use
    different vendors and different technologies
  • NASA will selectively use WDM electronics to
    interface to RONs and directly light dark fiber
    segments

Interoperability Issues
  • Interoperability between vendor optical equipment
  • Interoperability between testbeds and RONS
  • Availability of wavelengths for dedicated
    light-paths
  • Ability to change wavelengths
  • Interfaces and distance limitations
  • End-2-End performance troubleshooting issues
    LAN, desktop, applications

7
Key Challenges
  • End-to-end performance
  • LAN upgrades
  • Desktop configurations and optimizations
  • New applications
  • Security
  • NIST security requirements
  • Intrusion detection at 10 Gbps
  • Firewalls
  • Operational support
  • Contracts
  • Increase in number and complexity
  • Longer term contracts - ex 20-year IRUs
  • Funding
  • Vendors
  • Long lead time for equipment orders
  • Shortages of components
  • Monitoring
  • Network performance
  • Application performance
