[TICTOC]Enterprise Profile: Support for Non standard TCs

[Ron Cohen <[e-mail]>]

Hi,

I'm late to the game here. I apologize in advance if this has already been discussed and decided:

I can't figure out why the profile needs to support non-standard TCs, or what seems to be a strange combination of a NAT+TC devices:

"In PTP Networks that contain Transparent Clocks, timeTransmitters
   might receive Delay Request messages that no longer contains the IP
   Addresses of the timeReceivers.  This is because Transparent Clocks
   might replace the IP address of Delay Requests with their own IP
   address after updating the Correction Fields.  For this deployment
   scenario timeTransmitters will need to have configured tables of
   timeReceivers' IP addresses and associated Clock Identities in order
   to send Delay Responses to the correct PTP Nodes."

Is a standard TC allowed to change the source IP address of messages?

There should be a strong reason to require support for such devices in a standard profile.

Best,
Ron
