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
• Grid High Performance Network Group (GGF)
• Replication Network Group (GGF)
• IETF (possible for some items)

5
Milestones Timelines

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

6
Work progress

• "Requirements for Asynchronous and Heterogeneous
  Data Transport"
• "Implementation requirements for a Transport
  system"
• "Evaluation of alternative bulk data transport
  mechanisms"
• "Transport Scenarios and Requirements
• "Requirements for a General Transport Protocol
• Multicast transport solutions
• Parallel Data Transfers solutions in Grid

Document types and purposes

• GGF-draft documents (drafts_at_gridforum.org)
• 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.
