leveraging network expertise
Leveraging Network Expertise
  • Potential collaborative applications
    • Bridge barriers using network expertise
  • Emphasis on regional academic inst.
    • Local R1’s and HBCU’s
  • Identified several opportunities, but..
    • Long lead times & resource limitations
    • Limited impact
novel radical approach
Novel (radical) Approach
  • Rethinking the network fundamentals
    • 20 year technology lifetime
      • Rapid changes in optical technology
    • No legacy mindsets
  • Protocol simplification
    • Elimination of round trip handshakes
    • Optimized implementation
      • Functional placement: optics, electronics & software
      • Low latency & high performance
    • No data buffering in network
    • Intelligence concentrated at network edge
network technology
Network Technology
  • Optical Burst Switching
    • Switched light path dWDM network
    • no electro-optical conversion or buffering
  • Just in Time control protocol
    • Tell and go network control protocol
  • Data transparent to intermediate network
    • no assumptions made on signal format or rate
      • Analog and various digital signals
jit comparison to tcp
JIT Comparison to TCP
  • No buffering
  • More optimistic
  • Less latency
    • connection est.
    • error recovery
  • No slow start
    • Less time to deliver data once started
research relationships
Research Relationships
  • VCC: NASA Ames (NAS)
    • OBS Network Adapter & LAN
    • Applications over JIT / OBS
  • Jumpstart: DoD (ITIC & ARDA)
    • Just in Time definition, implementation, evaluation in ATDnet (NSA-LTS to NRL)
    • OBS network modeling and analysis
    • Future: routing & net management
  • Under exploration: DoE (transport layer)
grid computing applications
Grid Computing Applications
  • GridIR
    • proposed information retrieval service
    • secure database indexing, searching, retrieval, and discovery on the Grid
    • Working closely with Global Grid Forum
  • Grid tools over JIT – OBS
    • Exploring, designing, porting
    • Evaluating, benchmarking, improving
vcc grid testbed
VCC Grid Testbed
  • Expansion in progress (Beta)
    • 2 clusters + 1 Stand Alone Master
      • 7 slave + 1 master node per cluster
      • Fast Ethernet connected
    • Each node has
      • 2x 1.56 GHz AMD Athlon 1800+ MP
      • 1 GB DRAM slave, 2 GB DRAM master
      • 40 GB HD slave, 2x 40 GB HD master
    • 900 GB RAID Direct Attached Storage
    • 30 GB x 7 DLT stacker
  • Additional expansion planned for Y2
