2. Before I Share My Views At lectures, symposia, seminars, or
educational courses, an individual presenting information on IEEE
standards shall make it clear that his or her views should be
considered the personal views of that individual rather than the
formal position, explanation, or interpretation of the IEEE.

4. Ethernet: History and Relation to 802 History of LMSC 1st
meeting Feb 1980. Originally known as the Technical Committee on
Computer Communications (TCCC or T-Triple-C). Originally LAN, MAN
scope added later LMSC consists of SEC (802.0): Sponsor Executive
Committee WGs/TAGs (802.x): Working Groups and Technical Advisory
Groups Examples of Active WGs/TAGs Notice the historic success of
odd numbered groups! 802.1, 802.3, 802.11, 802.15, 802.16, 802.17,
802.18, 802.19, 802.20, 802.21Version 1.0 SIEPON Workshop April

5. Ethernet: Organization and Process Organization Each Working
Group has its own leadership and projects called Task Forces Each
TF has its own leadership. Exists for the duration of the project
For Ethernet, 802.3 and its membership make up the Working Group.
Process Idea starts as a Call For Interest and then goes through a
long, thorough and strict process before becoming a standard.
Requires 75% approval (individual) Day-to-day technical work is
done in a group operating under .3 (SG/TF) Work has to be approved
by .3. Ensures compatibility etc. w/ prior projectsVersion 1.0
