Recommendation for implementations in unicast networks or networks with non-PTP bridges and routers. This is an informal but often implemented profile, based on the "default" profile in Annex J.3.
Annex A.9
profileVersion:
1.0
Annex J.3.1
profileIdentifier:
00-1B-19-00-01-00
Annex J.3.1
Specified by:
Precise Networked Clock Synchronization Working Group of the IM/ST Committee of the IEEE
Not specified. Any valid unicast transport mechanism may be used, e.g. as specified in Annexes D to I of IEEE1588
Annexes D to I
Multicast or Unicast
All messages are sent in unicast. Unicast negotiation is used by default, but a management procedure could be used.
Annex A.9.3, A.9.4.2
BMCA
Default BMCA, as specified in clause 9.3.2.
Annex A.9.4.1, J.3.3
Path Delay Measurement
Uses delay_request/response mechanism by default. Peer delay mechanism is optional.
Annex A.9.4.2, J.3.3
PTP Management
Optional.
Annex A.9.4.1
Clock Identity
Standard PTP behaviour
7.5.2.2
Message Types
Used: Announce, Sync, Follow-up, Delay_Req, Delay_Resp, Signaling Not used: Pdelay_Req, Pdelay_Resp, Pdelay_Resp_Follow_Up The use of Management messages is permitted.
