IEEE802/IETF vs. 3GPP/3GPP2 Protocol Architecture IETF, IEEE802 3GPP/3GPP2 General building blocks Single protocol functions Adoption open to market Contribution by individuals Network architecture Specification of a network Often compulsory Corporate membership Aik Chindapol SCR 12/10/2004-2
2 The Beginning of IEEE 802 First meeting of the IEEE Computer Society Local Network Standards Committee, Project 802, in Feb ithe project number 802 was simply the next number in the sequence. i Later renamed to LMSC : LAN/MAN Standardization Committee Work was on one LAN standard, with 1 to 20 MHz, divided into: i Higher Level Interface (HILI). imedia Access Control (MAC), and i Physical layer (PHY) A year later three MACs: CSMA/CD, Token Bus, and Token Ring. Further MAC and PHY groups addded i , , , , Unifying themes of IEEE P802 i Common upper interface to the Logical Link Control (LLC) sublayer, i Common data framing elements Aik Chindapol SCR 12/10/ IEEE 802 Process Membership iindividual itechnical decisions (proposal selection, technical changes) require 75% approval Process iformation of the new group via a study group icall for contributions iproposal presentation and discussions i Downselection icreation of the draft document iworking group letter ballot (and recirculations) i Ballot responses: Approve or Disapprove with technical comments ievery comments need to be resolved isponsor ballot (and recirculations) iieee Standard publication Aik Chindapol SCR 12/10/2004-4
