[802.3_DIALOG] Call for interest - Improving PTP Timestamping Accuracy on Ethernet Interfaces

Dear Colleagues,

The following request for agenda time for a call for interest has been received from Steve Gorshe. It will be discussed at the IEEE 802 LMSC July 2019 Plenary meeting in Vienna, Austria. If you have any questions please get in touch with either Steve Gorshe <steve.gorshe@xxxxxxxxxxxxx> or myself directly.

Applications in which Precision Time Protocol (PTP) (e.g., IEEE Std 1588 or IEEE Std 802.1AS) is carried over Ethernet interfaces have become increasingly important. A growing number of applications benefit from being able to communicate frequency and time synchronization information over Ethernet. Emerging important potential Ethernet applications such as 5G mobile radio access networks require increased PTP accuracy. Unfortunately, the increased complexity of several recent IEEE Std 802.3 PHYs have inadvertently introduced limitations or degradations of the potential PTP accuracy. In some cases, the decreased PTP accuracy is related to a discrepancy between IEEE Std 802.3 and IEEE Std 802.1AS/1588 reference points. Addressing these issues will increase the scope of applications in which Ethernet can be deployed. This Call for Interest is to assess the support for the formation of a Study Group to explore the potential markets requirements and feasibility of amending the IE!
 EE 802.3 Ethernet standard to support high accuracy frequency and time synchronization.

----

The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 15th July. A call for interest consensus building meeting has been scheduled to occur from 19:30 to 20:30 on the evening of Tuesday 16th July. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 18th July.

Best regards,
David Law, Chair, IEEE 802.3 Ethernet Working Group
