I have always been assuming that we would do this over a timing FEC -
not reserved labels - not special types - ordinary MPLS with a timing
semantics attached to the label(s).
What I would also like to see is an encapsulation that works for both
NTP and 1588 - i.e. put the corrections in a well known place at the
front of the packet (we have to pick a single TS format), followed by
the timing payload (NTP, 1588 or foo), then fix it all up at the edge of
the network, either via a slave timeserver, of via correcting the packets.
