6 igrid 2002 (3 of 12) September 24-26, 2002, Amsterdam, The Netherlands 28 demonstrations from 16 countries: Australia, Canada, CERN, France, Finland, Germany, Greece, Italy, Japan, The Netherlands, Singapore, Spain, Sweden, Taiwan, United Kingdom, United States Applications demonstrated: art, bioinformatics, chemistry, cosmology, cultural heritage, education, high-definition media streaming, manufacturing, medicine, neuroscience, physics, tele-science Grid technologies demonstrated: Major emphasis on grid middleware, data management grids, data replication grids, visualization grids, data/visualization grids, computational grids, access grids, grid portals 25Gb transatlantic bandwidth (100Mb/attendee, 250x igrid2000!)
7 (3b of 12) Experimental Networks High-performance trials of new technologies that support application-dictated development of software toolkits, middleware, computing and networking. Provide known and knowable characteristics with deterministic and repeatable behavior on a persistent basis, while encouraging experimentation with innovative concepts. Experimental Networks are seen as the missing link between Research and Production Networks.
8 What is a LambdaGrid? (3c of 12) A grid is a set of networked, middleware-enabled computing resources. A LambdaGrid is a grid in which the lambda networks themselves are resources that can be scheduled, like all other computing resources. The ability to schedule and provision lambdas provides deterministic end-to-end network performance for real-time or time-critical applications, which cannot be achieved on today s grids.

12 The only formula s λ # λ(rtt) 200 e(t 2002) rtt Now, having been a High Energy Physicist we set c = 1 e = 1 h = 1 and the formula reduces to: # λ 200 e(t 2002) rtt (6 of 12)

15 Current technology λ+ (re)definition Current (to me) available technology consists of SONET/SDH switches, 10 gig ethernet and dark fiber environments Optical switch installed (this week)! DWDM+switching included Starlight/NetherLight deploy VLAN s on Ethernet switches to connect [exactly two] ports (but also routing) We want to understand routerless limited environments So redefine a λ as: (9 of 12) a λ is a pipe where you can inspect packets as they enter and when they exit, but principally not when in transit. In transit one only deals with the parameters of the pipe: number, color, bandwidth
16 (9a of 12) MEMS optical λswitch (CALIENT)
17 So λwhat are the facts Costs of fat pipes (fibers) are one/third of cost of equipment to light them up Is what Lambda salesmen tell me Costs of optical equipment 10% of switching 10 % of full routing equipment for same throughput 100 Byte 40 Gb/s -> 20 ns to look up in 140 kentries routing table (light speed from me to you!) Big sciences need fat pipes Bottom line: look for a hybrid architecture which serves all users in a cost effective way (10 of 12)
