If we ignore issues associated with existing chipsets that support
1588/E and 1588/UDP/IP, my preferred approach would be 1588/MPLS. Indeed
I might be tempted to significantly reduce the protocol options in this
environment. i.e. create a new 1588 protocol mapping which runs over a
PTP FEC.
We need to think whether we would need to translate into one of the more
common client mapping via boundary clock, or whether we could do direct
protocol mapping, but I am concerned at the number of layers that we
need if we retain the Ethernet or the IP headers.
