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

• 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

9
802.3/Cor2 WG Motion

• Request that IEEE 802.3 requests that the EC
  forward IEEE P802.3-2005/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 P802.3-2005/Cor 2 for Sponsor
  ballot.
• M Bob Grow
• S Pat Thaler

11
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 10-day
  electronic ballot to leave on the June RevCom
  agenda.

12
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

13
Higher Speed SG extension

• Motion (if removed from consent agenda)
• The LMSC approves extension of the 802.3 Higher
  Speed Study Group.

14
Energy Efficient EthernetSG 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

15
Energy Efficient Ethernet SG extension

• Motion (if removed from consent agenda)
• The LMSC approves extension of the 802.3 Energy
  Efficient Ethernet Study Group.

16
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.)

17
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 participants tolerance
• Im 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
