Hi,

We posted an updated version of the STUN Trace draft (-01).

- Added some Windows example code in the appendix. (Does not compile, but is taken from our implementation)
- Simplified draft by removing rich network feedback. This feature would have needed network upgrades.
- Added cross references to the PMTUD and TURN BW Probe drafts.
- Fixed nits and other small issues. (Probably added a few as well)

We are trying to keep the draft as lean as possible with only core functionality described. Hopefully that would make this an easy draft to read through.

Some of our products have already implemented this. Early lab testing actually discovered unintentional asymmetrical routing in one of our test labs. The draft of course also have other useful prospects, but I will let the individual reader ponder on that.

Remaining issues that should be fixed (If adopted or enough encouragement from the WG to continue)
- PATH-NODE probe defined in the draft. Is that useful?
- Timing? Do we need to talk about how often a probe can be sent out. Routers have ICMP DOS prevention code, but probably not standardised.
- Section 5.1 might need some additional wording if we want to be able to do a trace towards a TURN server.

Comments are of course welcome.

Pål-Erik

Abstract:
  After a UDP protocol such as RTP determines a network path is
  experiencing problems, a traceroute is often useful to determine
  which router or which link is contributing to the problem.  However,
  operating system traceroute commands follow a different path than the
  actual UDP flow which complicates troubleshooting.  A superior method
  is shown which is absolutely path-congruent with the UDP protocol
  itself, works on IPv4 and IPv6, and does not require administrative
  privileges on most operating systems.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
