How to use the control points for Reverse sync testing specified in "802.1AS Recovered Clock Quality Testing" ? #912

Hi All,

For the recovered clock testing using "reverse synch" method , it is specified in the "802.1AS Recovered Clock Quality Testing" document to use different control points as follows,

1) A control point to enable and disable the Reverse Sync/Follow-up messages . The default value of this is FALSE. 2) A control point to set the domain of Reverse Sync/Follow-up messages . For certification it is proposed that a different unique domain should be used than the one that’s being measured. When using in deployed networks a different domain shall be used. 3) A control point to set the Reverse Sync/Follow-up message rate as % of incoming rate . The default is defined in Section 6.3.

Here does "reverseSyncEnabled","reverseSyncDomain" and "reverseSyncRate" refers to the control variables which has to be newly created , and based on this variables the code has to be updated ? (or) Does these control points are already available in the opensource code. I have searched for this variables in the code, but was unable to find them.

Any suggestions/ references to how to proceed on this will be really helpful.

AFAIK AVnu/gptp doesn't support "reverse sync" method. BTW: 802.1AS/gPTP code has been moved to separate/dedicated repository AVnu/gptp

Hi PawelModrzejewski, Thanks for the comment. I will check the separate repository. so for Recovered clock certification testing, is there any other method to be followed other than 1PPS?

Thanks in advance.
