DNS IXFR, Notification, and Dynamic Update (dnsind) --------------------------------------------------- Charter Current status: active working group Chair(s): Randy Bush Internet Area Director(s): Frank Kastenholz Susan Thomson Mailing lists: General Discussion:namedroppers@internic.net To Subscribe: namedroppers-request@internic.net Archive: ftp://ftp.merit.edu/internet/documents/ietf/dns Description of Working Group: The DNS Incremental Transfer, Notification, 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: Done Consolidated review of draft-ietf-dns-ixfr-01.txt. Done Submit Incremental Transfer and Notify Internet-Drafts. Mar 95 Submit revised Incremental Transfer and Notify Internet-Drafts. Submit these revised documents for Proposed Standards. Jul 95 Publish Dynamic Update Internet-Draft and submit for Proposed Standard.
