Re: draft-ietf-ldup-replica-req-12.txt

Patrik,

Thanks for the info.

I was of the opinion that a "well-defined" replica topology (discernable by
the set of replication agreements created), would address potential
congestion.

There is no requirement that each replica communicate directly with every
other replica.  Replicas are required to "forward" updates received to
other replicas that have not yet "seen" the updates it knows about.
Replicas, then, could act as "gateways", thus using less network bandwidth
than if every replica had to communicate with every other replica.

But this would not have been understandable from just reading the replica
requirements draft.

Tim Hahn

The document was today approved by IESG, but, the IESG have concerns about
avoidance of congestion and over-chattiness of the replication protocol.

Today, LDAP is TCP only, and therefore LDUP, but, if LDUP is UDP-based or
something else, this have to be taking into consideration.
