DT/RG Goals The goal of this group is to provide a forum where parties interested in the secure, robust, high speed transport of data in the wide area and related technologies can discuss and coordinate issues, and develop standards to enable interoperability of implementations. This RG is expected to be a WG "factory" spawning off WGs in areas where sufficient common interest is shown

Todo list Coordination Required: 1. Grid High Performance Network Group (GGF) 2. Replication Network Group (GGF) 3. IETF (possible for some items)

Milestones Timelines 1.Document "Survey of Transport Protocols other than Standard TCP" submitted as GGF document. Eric He, EVL 2.Document "Extensions to HTTP for the Grid" submitted as GGF document. Andy McNab 3.Document "Recommendation for Standard Operations at Remote Sites" submitted as GGF document. Reagan Moore 4.Document "Protocol improvements to V1.0 of GridFTP" submitted as GGF document. Igor Mandrichenko

Work progress 1. "Requirements for Asynchronous and Heterogeneous Data Transport" 2."Implementation requirements for a Transport system" 3. "Evaluation of alternative bulk data transport mechanisms" 4. "Transport Scenarios and Requirements“ 5. "Requirements for a General Transport Protocol“ 6. “Multicast transport solutions” 7. “Parallel Data Transfers solutions in Grid”

Document types and purposes GGF-draft documents represent a draft document that has been submitted to the draft editor for discussion and eventually enter into the GFD review process (12 months). Informational Documents (GFD-I) (RG & WG) inform the community of an interesting and useful Grid-related technology, architecture, framework, or concept. Experimental Documents (GFD-E) (RG & WG) inform the community of the results of Grid related experiments, implementations, or other operational experience. Community Practice Documents (GFD-C) inform and influence the community regarding an approach or process that is considered to be widely accepted by consensus and practice in the Grid community. Recommendations Documents (GFD-R / GFD-R-P) document a particular technical specification or a particular set of guidelines for the application of a technical specification. The recommendations documents are intended to guide interoperability and promote standard approaches.

Next GGF meetings GGF9 (2003) will be held October , Chicago, IL, USA GGF10 (2004) will be held March 7-10 in Frankfurt, Germany. GGF11 (2004) will be held June 6-9 in Honolulu, Hawaii, USA.
