Michael

Am re-writing tunnelling section and wanted to come back to an issue you
raise in
http://www1.ietf.org/mail-archive/web/pcn/current/msg00687.html. 
" 1st problem: how do we find the ingress node X of the packet at its
PCN egress Y?"

I don't see why tunnelling makes this harder, assuming that the
signalling msg (or whatever is setting up the PCN-flow) follows the same
path as the data will. 

Thanks
phil
