NREN Overview
NRENs primary focus is delivering end-to-end
distributed data to/from the Columbia computing
facilities
  • Goals of the WAN
  • Enable large data-distribution, real-time
    interactive applications, and grid applications
    over a wide area, high-speed network
  • Enable distributed access to NASA research and
    engineering communities
  • Provide access to federal and academic entities
    via peering with High-Performance Research and
    Engineering Networks (HPRENs)

Overview
  • Scope
  • Supporting Columbia applications
  • Network technology research
  • Science and engineering application
    demonstrations
  • Remote field experiments
  • Status
  • Transition from ATM to lambda services
  • ARC link to JPL is up _at_ 500 Mbps
  • NLR contract was signed 8/31/05
  • ARC-GSFC link is next priority

Requirements
Columbia
  • Columbia, dedicated in October 2004, is one of
    the fastest operational supercomputer in the
    world
  • High fidelity integrated modeling and simulation
    applications running on Columbia will generate
    terabyte sized data sets.
  • Customers
  • all NASA Missions
  • 7 NASA centers
  • gt30 NASA-external PI institutions
  • Application requirements
  • Real-time distribution of terabyte data sets
  • Real-time visualization data analysis
    information products
  • Ubiquitous network access
  • International visibility and largesystem
    capacity require aggressive security

  • NREN Peering locations
  • Three Next Generation Internet eXchange (NGIX)
    Points
  • Potential for additional peering in other
    co-located sites

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

10
Optical Technologies
  • NREN has chosen Ciscos 6500 as a core connection
    platform for L2/L3 connectivity with LAN PHY
    hand-offs
  • NREN interfaces to NLRs Cisco 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

12
Challenges to establishing the network
  • End-to-end performance
  • LAN upgrades
  • Desktop configurations and optimizations
    (buffers, TCP tuning, etc.)
  • applications (e.g., BBFTP)
  • Operational support
  • Funding
  • Vendors
  • Long lead time for equipment orders
  • Shortages of components
  • Monitoring
  • Network performance
  • Application performance

13
Contract Issues
  • Time-frame for completing contracts
  • Which contract vehicle is the best to pursue?
  • No process for contract vehicle selection
  • More contracts
  • NLR for core
  • RONs, consortiums, ISPs for local loops
  • NISN and Indiana University for Out-of-Band
  • Increase in complexity, often requires HQ
    approval
  • Longer terms gt 5 years
  • Pre-pay discounts
  • Government contract limitations
  • Agreements vs. contracts

14
Security
  • Security Guidelines
  • Interpretation many of the documents
  • NIST Special Publication 800-18 - Guide for
    Developing Security Plans for Information
    Technology Systems
  • Computer Security Act 1987
  • OMB Circular A-130, Management of Federal
    Information Resources
  • OMB Circular A-130 Appendix III, Security of
    Federal Information Resources
  • Federal Information Security Management Act 2002
  • NASA Policy Directives Ames Procedures and
    Guidelines
  • OMB pressure for compliance
  • How do you provide end-to-end secure
    communications at 10 Gbps?
  • Firewall limitations
  • Crossing network boundaries
  • Unable to see individual packets at wire speeds
  • Need 10 Gbps intrusion detection
