  8. What is Lambda Data Grid? Grid Computing Applications • A service architecture • comply with OGSA • Lambda as an OGSI service • GRAM extension • add parameter of network resource • net resource co-allocation • on-demand and scheduled Lambda • GT3 implementation • contribute code back to GT3 Grid Middleware Data Grid Service Plane Network Service Plane Centralize Optical Network Control Lambda Service

  9. Grid Service Optical Interconnection Applications HTTP SOAP … TCP UDP … Generalized Label Multiplexing: Lambda, OBS, Fiber Switching,.. Fiber

  10. Lambda Hourglass • Data Intensive (DI) app requirements • HEP • Astrophysics/Astronomy • Bioinformatics • Computational Chemistry • Inexpensive disk • 1TB < $1,000 • DWDM • Abundant optical bandwidth • One fiber strand • 280 λs, OC-192 CERN 1-PB Data-Intensive Applications Lambda Data Grid Abundant Optical Bandwidth 2.8 Tbs on single fiber strand

  11. Lambda Data Grid details OGSI Ext OGSA • A framework providing optical paths for Data-Intensive applications • Service architecture • interacts w/ optical control • dedicated on-demand optical path • not on the public Internet • novel data-networking scheduling scheme Intelligent Midleware services DTS Ext Ext NRS Ext Ext Co-allocation Co-reservation GRAM GARA GT3 Services
