Introduction T The problem: support efficient/reliable/predictable peta-scale data movement in modern high-speed networks q Multiple data flows with varying priority q Default “best effort” network behavior can cause performance and service disruption problems T Solution: enhance network functionality with Qo. S features to allow prioritization and protection of data flows q Treat network as a valuable resource q Schedule network usage (how much bandwidth and when) 3

Testbed Expansion Status and Plans T A full time Ph. D student with network

Testbed Expansion Status and Plans T A full time Ph. D student with network background will start in the middle of March. T Existing Member: BNL and University of Michigan/Great Lake T New Site started: SLAC T Candidate Tier 2 sites for 2007 expansion: q University of Chicago / Indiana University q University of Oklahoma / University of Texas at Arlington q Boston University/Harvard T Further expansion to remaining Tier 2 site and other lower tier sites year 2008.

How to become (paid) participants T SW, NE, MW Tiers. T Read the MOU, Tera. Paths Addendum, provide critical feedback, and sign it. q ATLAS Tier 2 managers q Listed in https: //www. racf. bnl. gov/terapaths/project/documents/ T General a $30 K budget page and justification. T Send back to Dantong Yu. T I got a master budget page with $200 K (dispatched by DOE already) in total for this year. generated a subcontract acquisition and gave to our web req office. T Have a first Tera. Paths kick-off meeting via VRVS at the end of March. 11
