Hi Rodney,

It is great that IEEE 1588 has begun to consider the problem in the performance monitoring and diagnostics. It is definitely an important topic for a large scale synchronization network.
One interesting problem may arise, does SyncE have the same issue? If yes, do we need to consider a universal solution?


Dear SCSN members,

There is an ongoing revision to the IEEE-1588 standard in progress, which is projected to be v2.1 (i.e. compatible to 1588-2008, aka 2.0). The 1588 revision is still in an early draft stage, with several proposals under discussion.

At least three proposals for 1588 v2.1 relate to the topic of performance monitoring and diagnostics. Subscribers to this mailing list may be interested in those proposals, so I am posting information to SCSN.

If you are not already a member of IEEE-1588, you will need to join in order to view draft proposals. The process is simple, described in:

Some proposals under discussion in 1588 include:

Proposal for performance statistics that are accessed using management:
Proposal for clock to send its local performance measurements in a Signaling message
Proposal for a TLV that accumulates accuracy information along path from GM to slave
