DNS IXFR, Notification, and Dynamic Update (dnsind) --------------------------------------------------- Charter Last Modified: 2000-01-26 Current Status: Concluded Working Group Chair(s): Olafur Gudmundsson Randy Bush Internet Area Director(s): Thomas Narten Erik Nordmark Internet Area Advisor: Erik Nordmark Mailing Lists: General Discussion:namedroppers@internic.net To Subscribe: namedroppers-request@internic.net Archive: ftp://rs.internic.net/archives/namedroppers Description of Working Group: The DNS Incremental Transfer, Notification, and Dynamic Update Working Group is concerned with three areas of future DNS protocol development: 1. 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. 2. 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. 3. 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. Done Submit revised Incremental Transfer and Notify Internet-Drafts. APR 96 Submit Dynamic Update, Incremental Transfer, and Notify Internet-Drafts to the IESG for consideration as Proposed Standards. Internet-Drafts: No Current Internet-Drafts.
