RE: [AVT] Comments on draft-ash-avt-ecrtp-over-mpls-reqs-01.txt
Magnus and others,
This captures very well the concerns I expressed on the AVT session,
I just want to stress point 5 a little bit. A brief summary of how
all candidate schemes (CRTP, eCRTP and ROHC) should be included,
explaining how each scheme would map to the needs, as well as what
would have to be added to make each scheme applicable.
