Overview

Overview

  • Information Technology focus

    • Novel optical networking techniques

    • Applications to Grid Computing

  • Target

    • bottlenecks in networked applications

    • Dearth of network expertise in applications researchers


Scope

Scope

  • Development of Proof of Concept

    • Novel Optical LAN and Adapters

  • Grid computing applications

    • Information retrieval tools

    • Porting grid tools to PoC LAN

    • Testbed

  • Leveraging network expertise


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
