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 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
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 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 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
No buffering More optimistic Less latency
connection est. error recovery
No slow start Less time to
deliver data once started

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 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 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
