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 2012 IEEE P802.3 Maintenance report July 2008 Plenary Copyright 2012 Page 4 Page 4

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 SIEPON Workshop April 2012 IEEE P802.3 Maintenance report July 2008 Plenary Copyright 2012 Page 5 Page 5
