Hi, This was one of the point that have been highlighted at last tictoc meeting (see http://www.ietf.org/proceedings/78/slides/tictoc-2.ppt). A possible approach could be to mark in some way the IPSEC tunnel to inform PTP packets are carried (e.g. RES bits), and rather than modify the correction field, implement some sort of control of the delays (this woudl also avoid layer vialoation issues). A related discussion was held at last Q13-Q4-Q2 joint meeting in Geneva.

I believe time can be signed (and encrypted), the per-hop adjustment information probably cannot. -- Mikael Abrahamsson email: [email protected] _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc _______________________________________________ TICTOC mailing list [email protected] https://www.ietf.org/mailman/listinfo/tictoc
