I-D Action:draft-ietf-rserpool-asap-18.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Reliable Server Pooling Working Group of the IETF.

	Title           : Aggregate Server Access Protocol (ASAP)
	Author(s)       : R. Stewart, et al.
	Filename        : draft-ietf-rserpool-asap-18.txt
	Pages           : 56
	Date            : 2007-11-18

Aggregate Server Access Protocol (ASAP) in conjunction with the
Endpoint Handlespace Redundancy Protocol (ENRP)
[I-D.ietf-rserpool-enrp] provides a high availability data transfer
mechanism over IP networks.  ASAP uses a handle-based addressing
model which isolates a logical communication endpoint from its IP
address(es), thus effectively eliminating the binding between the
communication endpoint and its physical IP address(es) which normally
constitutes a single point of failure.

In addition, ASAP defines each logical communication destination as a
pool, providing full transparent support for server-pooling and load
sharing.  It also allows dynamic system scalability - members of a
server pool can be added or removed at any time without interrupting
the service.

ASAP is designed to take full advantage of the network level
redundancy provided by the Stream Transmission Control Protocol
(SCTP) [RFC4960].  Each transport protocol, other than SCTP, MUST
have an accompanying transport mapping document.  It should be noted
that ASAP messages passed between PE's and ENRP servers MUST use the
SCTP transport protocol.

Thanks,

I have removed everything that seems clear to me.

Okay, that it is correct is the only thing I needed to know.

Re: AD comments on draft-ietf-rserpool-enrp-17, draft-ietf-rserpool-asap-17, draft-ietf-rserpool-common-param-13

I have reviewed the changes. Some comments and unfortunately I think
some few additional fixes are needed.

I-D ACTION:draft-ietf-rserpool-enrp-18.txt

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Reliable Server Pooling Working Group of the IETF.

	Title		: Endpoint Handlespace Redundancy Protocol (ENRP)
	Author(s)	: Q. Xie, R. Stewart, M. Stillman, M. Tuexen, A. Silverton
	Filename	: draft-ietf-rserpool-enrp-18.txt
	Pages		: 41
	Date		: 2007-11-20
	
The Endpoint Handlespace Redundancy Protocol (ENRP) is designed to
   work in conjunction with the Aggregate Server Access Protocol (ASAP)
   to accomplish the functionality of the Reliable Server Pooling
   (RSerPool) requirements and architecture.  Within the operational
   scope of RSerPool, ENRP defines the procedures and message formats of
   a distributed, fault-tolerant registry service for storing,
   bookkeeping, retrieving, and distributing pool operation and
   membership information.
