Hi Tramsters,

We published a draft today describing extensions to STUN that enables simple communication between the endpoint and the network.

Name:		draft-martinsen-tram-discuss
Revision:	00
Title:		Differentiated prIorities and Status Code-points Using Stun Signalling (DISCUSS)
Document date:	2014-02-12
Group:		Individual Submission
Pages:		13
URL:            http://www.ietf.org/internet-drafts/draft-martinsen-tram-discuss-00.txt
Status:         https://datatracker.ietf.org/doc/draft-martinsen-tram-discuss/
Htmlized:       http://tools.ietf.org/html/draft-martinsen-tram-discuss-00

The main goals for now:

 - Make it easy for an application to communicate its intent to the network (QoE) without needing access to the lower layers of the IP stack. Sending a STUN packet would be an easy solution for the application.
- Make it easy for the network to process information from the endpoint. STUN have nice characteristics that makes it easy for network elements to pick it up.
- Create a tightly defined set of STUN attributes that does not leak unnecessary information.

To describe the draft using established mechanisms; think of it as extended DSCP markings with ECN capabilities sent in-band using STUN.

I realize the TRAM agenda is packet, but hopefully we would fine time to discuss if this is something useful that fits under the TRAM charter.
