3. 14 July 2000TWIST 2000 -- ghb@dast.nlanr.net The National Laboratory for Applied Network Research Established in 1995, as cooperative agreement with three sites, SDSC, NCSA, PSC Initially focused on the design, development and deployment of the NSF/MCI very high performance Backbone Network Service (vBNS) Established a new level of networking capability to support research Evolved to provide services to maintain, operate and support the use of the vBNS, Abilene and other high-performance networks. Recently provided direct support to researchers by leveraging the use of distributed resources.
