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.
