[TICTOC] Enterprise profile update

[Douglas Arnold <[e-mail]>]

Hello Everyone,

Please note that a new version of the proposed Enterprise Profile was
uploaded approximately one month ago.
http://datatracker.ietf.org/doc/draft-ietf-tictoc-ptp-enterprise-profile/

Changes, other than minor typos, are:

1. Elimination of the Unicast only and Multicast only modes of operation.
 The only mode of operation is the hybrid multicast/unicast mode.  In this
mode the master sends sync and announce as multicast, and it responds to
delay request messages "in kind".  In other words a delay response is
unicast if the delay requests is unicast, and multicast if the delay
requests is multicast.

2. The option for multiple simultaneous masters uses separate timing
domains instead of the alternate master flag.  Here I am attempting to
guess how the next revision to IEEE 1588 will go.

3.  The prohibition against distributing time zones remains unchanged.  See
the posts to the tictoc reflector by Kevin Gross and John Fletcher for a
good discussion on the pros and cons of this choice.

Please take a look and tell me what you think?
