O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Talk Outline  What are we trying to do?  Why do it?  How (we all sort of know don’t we)?  How can we get there from here?  …Where will that be?

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY DOE Science  DOE has bigger problems (drivers) … (and less money) than any other three- letter agency  But with it, we are trying to do things like:  Climate Modeling  Supernova modeling  Genomics (and proteomics)

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Climate Modeling North American model at 400Km resolution North American model at 60Km resolution The Rockies block the atmospheric circulation and are important geneses regions for the weather systems that form the North Atlantic Storm Track. They are poorly represented in low resolution models.

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY PetaScale Science  Climate modeling today => TB data sets  Still adding carbon chemistry  Still refining resolution  You saw DOE Road Map table showing PB requirements in 2-3 years  Supernova modeling just going from 2 1/2 dimensions to 3D - this is a PB problem today  Genomics and Proteomics will dwarf these  …and then of course there is High Energy …but

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY We run hard into network limits…  There is some VERY nice work being done on TCP  But that will just emphasize router delay  And expose congestion, even where it coexists with it  There is nice work being done to extend MPLS  But that does not eliminate jitter  And imposes additional overhead  And there is still the tyranny of layers

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY What are we trying to do?  We are trying to break out of the limitations of conventional networks  TCP/IP  Firewalls, and layers  Small-frame technologies  Take advantage of the real throughput available in optical networks today at the SONET layer  Develop the techniques needed within 2-3 years for DOE Peta-scale science  Use switched-circuits as a solution we can start on today

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Restating the Problem -  Networks will soon offer 40 Gbs channels  Typical multi-stream throughput limited to 5-6Gbs, and programming multi-steam is hard - hero efforts yield 9-10Gbs  Typical single-steam throughput to a single application ~1Gbs, even on a tuned network - hero effort yields 5-6Gbs  Firewalls throw it away anyway

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Solution -  We won’t have line-rate optical packet-switching anytime soon  No photonic transistors  No photonic memory buffers  We can do optical circuit switching  Useless for most commercial networks  Doesn’t aggregate for economy of scale  But bulk P2P purchases can be extremely attractive  A good match for DOE high-performance science applications which require both bandwidth and precision  Petabyte file transmission in 2-3 years  Tera-scale interactive visualization ASAP  Remote real-time instrument control now

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY UltraNet Research Testbed  Build a sparse, lambda-switching, dedicated channel-provisioning testbed  Connect hubs close to DOE’s largest Science users (but let the user labs pay last-mile costs)  Provide an evolving matrix of switching capabilities  Separately fund research projects (e.g., high- performance protocols, control, visualization) that will exercise the network and directly support applications at the host institutions

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY The Resources:  Off hours capacity from Esnet  Probably 2 x OC48 between Sunnyvale and Chicago in the northern route  Dedicated Lambdas on NLR  Two 10G lambdas between Chicago and Sunnyvale  Possibly more in year two or three  Two dedicated lambdas on the ORNL Chicago-Atlanta connector

O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Resources Cont.  A progression of switching technologies  Start with Ciena, Cisco, or Sycamore  Migrate to Calient, Glimmerglass all-optical or a hybrid  Some Local Storage  Logistical Storage Depot (prior to local application development)  Progression of experimental point-to-point transport technologies (plus legacy)  Fiber channel  Infiniband  Migrate to the Production ESnet environment
