Description of Working Group

     The DNS Incremental Transfer, Notify, and Dynamic Update
     Working Group is concerned with three areas of future DNS
     protocol development:

     Incremental Zone Transfer - As the sizes of some zone files
     have grown quite large, it is believed that a protocol addition
     to allow the transfer of only the changed subset of a zone will
     reduce net traffic and the load on critical servers.

     Change Notification - There can be large time intervals during
     which at least one secondary has data that is inconsistent with
     the primary.  The proposed ``notify'' mechanism (where the
     primary sends a message to known secondaries) facilitates fast
     convergence of servers vis-a-vis consistency of data in the
     zones.

     Dynamic Update - The need to frequently update small portions
     of a large zone and to have those updates propagate is
     perceived.

Goals and Milestones

Jul 1994   Consolidated review of draft-ietf-dns-ixfr-01.txt.

Nov 1994   Submit Incremental Transfer and Notify Internet-Drafts.

Mar 1995   Submit revised Incremental Transfer and Notify
           Internet-Drafts.  Submit these revised documents for Proposed
           Standards.

Jul 1995   Publish Dynamic Update Internet-Draft and submit for Proposed
           Standard.
