Thanks Dan,

we also updated the document just now based on feedback we have received privately. Thanks to everybody who has reached out to us! Very much appreciated.

The two major updates in this version are:

- removed the documents that we believed this document will update. We were conviced that it will not - Also, altered the represenation of the reverse traceroute request and response to better reflect what's in RFC 792

There are a few more updates in the pipeline. Please keep comments coming (preferably on the mailing list, so everybody can be part of the conversation).

Thanks,

Rolf

This is a great design and the statelessness also reduces amplification attack.

Dear Int-Area WG,

the last time we presented Reverse Traceroute a comment was made that ICMP as 
being used today usually does not keep state around. We still believe that it 
does no real harm in this case but, as an alternative that does not need state, 
we have written up a stateless alternative for Reverse Traceroute.

Where's the catch? Well, stateless reverse traceroute can always enumerate the 
routers on the reverse path, but it can potentially fail to provide an RTT 
measurement for each hop. But read for yourself:

Happy to take comments.

Best,

Rolf
