Scope
• This standard defines Ethernet local area, access and metropolitan
area networks. Ethernet is specified at selected speeds of operation;
and uses a common media access control (MAC) specification and
management information base (MIB). The Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) MAC protocol specifies
shared medium (half duplex) operation, as well as full duplex
operation. Speed specific Media Independent Interfaces (MIIs)
provide an architectural and optional implementation interface to
selected physical layer entities (PHY) interfaces. The physical layer
encodes frames for transmission and decodes received frames with
the modulation specified for the speed of operation, transmission
medium and supported link length. In addition to the local area
network applicatoins, Other specified capabilities include: PHY
control and management protocols types for access networks, PHYs
suitable for metropolitan area network applications, and the
provision of power over selected twisted pair PHY types.
P802.3-2005/Cor 2 content
P802.3-2005/Cor 2
• WG ballot passed with no negatives
– 13 comments, most out of scope
– Commenters willing to raise out of scope
issues in P802.3REV.
• WG authorized Sponsor ballot
• WG authorized RevCom submittal without
further WG vote
802.3/Cor2 WG Motion
Request that IEEE 802.3 requests that the EC forward IEEE P802.32005/Cor 2 D2.0 to Sponsor ballot.
The result of the above is that the IEEE 802.3 Working Group chair
will request EC approval for submission of IEEE P802.3-2005/Cor 2
to the RevCom conditional upon successful completion of the initial
Sponsor ballot (not seeking separate WG approval for RevCom
submittal is felt appropriate for expedited processing of a
Corrigenda).
Request that IEEE 802.3 authorises the IEEE 802.3aw Task Force
to conduct meetings and recirculation ballots as necessary to
resolve comments received during Sponsor Balloting.

P802.3-2005/Cor 2 to
Sponsor ballot
Motion:
The LMSC approves P802.32005/Cor 2 for Sponsor ballot.

P802.3-2005/Cor 2 to RevCom
Motion:
The LMSC approves submittal of
P802.3-2005/Cor 2 to RevCom for
June consideration if initial ballot is
successful, and subject to an EC 10day electronic ballot to leave on the
June RevCom agenda.

Higher Speed SG progress
• Begun selecting objectives
– Strong consensus supporting 100 Gb/s data rate
– Disagreement on including 40 Gb/s data rate
– Support for multiple link reach objectives
• Multi-mode fiber 100m reach
• Single-mode fiber 10km reach
• Single-mode fiber 40km reach
• Interims scheduled for April and May
• Extension approved by WG
Higher Speed SG extension
Motion (if removed from consent agenda):
The LMSC approves extension of
the 802.3 Higher Speed Study
Group.
Energy Efficient Ethernet
SG progress
• Begun selecting objectives
– Strong consensus to specify speed change to reduce
energy consumption
• Not as easy as we would wish
• May require some retraining for GbE and 10GbE DSP
• Variability of cable channel over time is significant challenge
– Interest in supporting wake-up from Standby power
management state (almost no power consumption)
– Support for including Backplane Ethernet PHY types
• Interims scheduled for April (tentative) and May
• Extension approved by WG
Energy Efficient Ethernet
SG extension
Motion (if removed from consent agenda):
The LMSC approves extension of
the 802.3 Energy Efficient
Ethernet Study Group.
DT – 802 TF schedule
• Would more EC members participate in
the 802 Task Force if its schedule were
consistent. (This might allow WG
commitments to be scheduled to allow
better attendance.)
DT – IEEE-SA process
• Most IEEE-SA process changes will be implemented in
myProject
– Interest area identification of participants
– Voting membership list
– Per project affiliation declaration
• There have been complaints about some changes or
their implementation
– myProject Information will not be shared with other parts of IEEE
– IEEE-SA privacy policy stating this is coming
– IEEE-SA recognizes they must balance adminsitrivia benefits
and protections with standards participant’s tolerance
• I’m available to help any of you understand the plan
– There will be a series of changes during this year
– Concerns from participants are being considered
