Hi All,

Please review and comment on 'NSIS Network Service Layer Protocol QoS Signaling Proof-of-Concept' http://www.ietf.org/internet-drafts/draft-ash-nsis-nslp-qos-sig-proof-of-concept-01.txt.  This is a proposed NSIS NSLP QoS signaling model and Qspec template, as described in 'NSLP for Quality-of-Service Signaling' http://ietf.org/internet-drafts/draft-ietf-nsis-qos-nslp-01.txt.

John Loughney suggested such proof-of-concept models in his posting to the NSIS list on 19 November http://www1.ietf.org/mail-archive/working-groups/nsis/current/msg03557.html:
"One suggestion would be to take 1 or 2 existing QoS models and detail them in a separate draft, as a sort of proof-of-concept for the QoS NSLP.  These documents could exist as individual submissions, but could be considered by the WG."

Also, in his 27 October posting http://www1.ietf.org/mail-archive/working-groups/nsis/current/msg03427.html, John said: "My opinion about this is that there are already a number of QoS models specified outside of the IETF, for example the ITU, 3GPP, etc.  I do not think it wise for the IETF to make there own QoS model, but to allow consenting peers to use the QoS NSLP with particular QoS models.  I think one way to achieve this is to use IANA registries to register QoS models, and the QoS NSLP to signal these."

The proposed QoS signaling model is based on 3 ITU-T Recommendations on QoS signaling:
1. [TRQ-QoS-SIG] "Signaling Requirements for IP-QoS," January 2004.
2. [Y.1541] "Network Performance Objectives for IP-Based Services," May 2002.
3. [E.361] "QoS Routing Support for Interworking of QoS Service Classes Across Routing Technologies," May 2003.
These Recommendations are summarized in the draft.

We welcome your comments, suggestions, and inputs on the draft. 

Hopefully this work can also be discussed at IETF-59/Seoul.

Thanks,
Jerry Ash

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: NSIS Network Service Layer Protocol QoS Signaling Proof-of-Concept
	Author(s)	: J. Ash

This draft describes a proof-of-concept example of NSIS Signaling Layer 
Protocol (NSLP) for signaling QoS reservations in the Internet.  The 
example is based on standardization work in the ITU-T of QoS signaling 
requirements. The QoS-NSLP is independent of the underlying QoS 
specification or architecture and provides support for different 
reservation models.  Together with the NSIS Transport Layer Protocol 
(NTLP), the NSLP provides functionality similar to RSVP and extends it. 
This draft provides a proof-of-concept example of the NSIS NSLP for QoS 
signaling.  The example is based on standardization work in the ITU-T on 
QoS signaling requirements [E.361, TRQ-QoS-SIG], and is specified in 
terms of the QoS-signaling model and Qspec template given in the 'NSLP 
for QoS Signaling' specification [QoS-SIG].
