Dear Colleagues,
As already announced <
https://www.ieee802.org/3/email_dialog/msg01178.html>, IEEE 802.3 will hold its July 2021 plenary session telephonically, from Monday 12th July, through Thursday 22nd
July 2021. There will be an IEEE 802.3 Opening plenary meeting on Monday 12th July 2021, an IEEE 802.3 Mid-session plenary meeting on Thursday 15th July 2021, and an IEEE 802.3 Closing plenary session on Thursday 22nd July 2021. These meetings will be held
from 14h00 UTC (07h00 PDT, 08h00 MDT, 09h00 CDT, 10h00 EDT, 15h00 BST, 16h00 CEST, 19h30 IST, 22h00 CST, 23h00 JST) to 16h00 UTC.
The draft agendas, as well as liaison letters received so far, are available in the minutes area <
http://www.ieee802.org/3/minutes/jul21/index.html> and will be updated as required prior to
the meeting. The agenda will be approved at the meeting.
Subgroup (Task Force, standing committee, and any appropriate ad hocs) meetings will be held from Tuesday 13th July 2021 UTC through Wednesday 21st July 2021 UTC, excluding Friday 16th July 2021 UTC through Sunday 18th July 2021 UTC. Meeting information
is provided on the IEEE 802.3 Call and Meeting Calendar <
https://ieee802.org/3/calendar.html>, further information regarding subgroup meetings are provided below.
Payment of a registration fee is required by anybody that attends any meeting held during this plenary session, payment of a single fee allows you to attend all meetings during the plenary session. This registration
fee will help offset the costs incurred by the cancellation of the July physical plenary. The registration fee will be 50.00 USD for all attendees until Wednesday 23:59 UTC on 30th June 2021 after which it will increase to 75.00 USD
for all attendees. The registration web site can be accessed at <https://cvent.me/D5LYLq>.
As a reminder, attendance credit toward membership requires at least 75% attendance during the plenary session, as well as payment of the registration fee. As a result, you will need to record attendance at a meeting on at least six of the eight meeting
days of the July 2021 IEEE 802.3 plenary session, independent of how long a particular subgroup might be meeting.

Greater than 10 Mb/s long-reach point-to-point single pair Ethernet PHY Study Group Call for Interest
-----------------------------------------------------------------------------------------------------
The following request for agenda time for a Greater than 10 Mb/s long-reach point-to-point single pair Ethernet PHY Study Group Call for Interest has been received from George Zimmerman.
----
The work begun in the IEEE 802.3 Enhancements to Point-to-Point Single Pair Ethernet Study Group for a higher-speed long reach point-to-point single pair Ethernet has garnered significant interest in a variety of use cases for long reach at speeds above
10 Mb/s. This call for interest is to consider continuing the work investigating a potential project for one or more greater than 10 Mb/s point-to-point PHYs using single-pair media at reaches beyond the reach of the existing 802.3 single-pair PHYs at the same
rate.

Cut-Through Forwarding (CTF) among Ethernet Networks
----------------------------------------------------
Wednesday 7th July 2021 from 14h00 to 15h20 UTC
ABSTRACT:
Cut-Through Forwarding (CTF) is a known method to improve the delay performance in bridged Ethernet networks and finds application in areas that require this performance.
In contrast to the store-and-forward operation, CTF allows frame transmission in bridges before reception is completed. Although not standardized in IEEE 802, CTF is already implemented in commercial products. It is therefore technically feasible, and
standardizing CTF in IEEE 802.1 and IEEE 802.3 would enable interoperable implementations.
This tutorial introduces CTF on a technical level, explains application areas, markets and use-cases for CTF, and addresses aspects of standardizing CTF in IEEE 802.1 and IEEE 802.3.
This tutorial has been developed within the IEEE 802 Nendica CTF Study Item.
