1 doc.: IEEE /1191r4 Submission November 2004 Mike Moreton, STMicroelectronicsSlide 1 AP Architecture Thoughts Mike Moreton, STMicroelectronics

2 doc.: IEEE /1191r4 Submission November 2004 Mike Moreton, STMicroelectronicsSlide 2 Introduction defines terms such as “Integration Function”, “Portal”, “DS”, “DSM” etc. Definition is deliberately vague –To allow different implementations Hence different companies have different views of what these terms actually mean –Almost any diagram is likely to be unacceptable to a majority of companies

3 doc.: IEEE /1191r4 Submission November 2004 Mike Moreton, STMicroelectronicsSlide distribution system (DS): A system used to interconnect a set of BSSs and integrated LANs to create an ESS distribution system medium (DSM): The medium or set of media used by a DS for communications between APs and portals of an ESS extended service set (ESS): A set of one or more interconnected BSSs and integrated LANs that appears as a single BSS to the LLC layer at any station associated with one of those BSSs integration: The service that enables delivery of MSDUs between the DS and an existing, non-IEEE LAN (via a portal) portal: The logical point at which MSDUs from a non- IEEE LAN enter the DS of an ESS. Definitions
