Technical Summary

The four drafts provide a set of protocols and parameter definitions
supporting Reliable Server Pooling requirements, as defined in RFC 3237. 
ASAP defines a protocol for communication between server pool members and
server pool users that supports functions such as server registration and
lookup, liveness detection and limited failover.  ENRP defines a protocol
for communication between name resolution servers that supports a
fault-tolerant registry function for handling pool operation and
membership information.  Parameter formats and codepoint assignments for
both ASAP and ENRP are provided in a Common Parameters specification. The
Policies draft defines methods of applying the Rserpool protocols in order
to achieve a variety of different pool usage policies.


Working Group Summary

The Working Group process was constrained by the relatively small number
of people actively involved (although those involved were committed to
doing implementations of the protocols).  Otherwise there was little
controversy within the group.

Document Quality

There are multiple implementations of both ENRP and ASAP protocols,
thanks to participants.  However, there are no vendors that have indicated
plans for implementation.  Based on this and the limited number of
participants, Experimental track seems appropriate.  We received detailed
comments and review from Scott Bradner and his help was greatly
appreciated.

Personnel

Document Shepherding is being provided by the Working Group chairs,
Maureen Stillman and Lyndon Ong.  Responsible Area Director is Magnus
Westerland.
