> I have very strong doubts about all the issues mentioned in sections 4 and 5
I have comments on 4.2 TDM PWs, 4.3 Codecs, and 4.4 MPLS signaling protocols. For TDM PWs the IETF followed its tao of requiring one MUST mode (RFC 4553) and allowing 2 MAY modes (RFCs 5086 and 5087). However, far from being a resounding triumph, this meant that a method considered inadequate by all who really understood the issues was mandated, while too equally adequate alternatives became optional. So this example actually shows a negative aspect of the procedure. Regarding the Code issue, multiple proposals were submitted, and the resolution was to mold two of them into a new combined codec with pieces of each. So this example is not relevant at all. Regarding CR-LDP vs. RSVP, once again there were two pre-existing solutions, and it was decided not to do any new work on one of them. But this left us with 2 mandatory to implement protocols (LDP and RSVP-TE) rather than a decision for CR-LDP which would have left a single mandatory protocol. So this actually a counter-example to the tao of having a single mandatory mode.
