Key Differences in WME+ and Fasttrack Protocols by Adrian Stephens

DESCRIPTION

This document outlines the key differences between WME+ and Fasttrack protocols as presented by Adrian Stephens from Intel Corporation. It covers the lack of flow identification for UNITDATA requests, the exclusive use of 802.1D tags in on-air packets, and the compatibility of these protocols with existing network architectures. The report discusses autonomous flow creation within STA MAC based on internal observations, flow admission, aggregation, and the normative behavior proposed for controls in these areas. It further delineates mandatory and optional statuses and provides insights on classification and prioritization.

Presentation Transcript

  1. WME+ / Fasttrack Differences Adrian Stephens (adrian.p.stephens@intel.com) Intel Corporation Adrian Stephens, Intel

  2. D-SAP & Data service • No Flow identification for UNITDATA request • 802.1D tags • On-air packets carry only 802.1D tags, not flow identifiers • Compatible with existing network architecture Adrian Stephens, Intel

  3. Flows • Flows can be created autonomously within the STA MAC based on observations of internal queue conditions or through MLME SAP • Flow Admission • Flow Aggregation • Known per-STA Aggregate schedule published by HCF Adrian Stephens, Intel

  4. Flow description • Rate based at MLME SAP • Rate based on-air signalling Adrian Stephens, Intel

  5. Admission, Aggregation and Scheduling behaviour • Normative behaviour to be proposed for Admission, Aggregation and Scheduling • Parameters unused by this normative behaviour will be removed from the spec Adrian Stephens, Intel

  6. Mandatory or Optional status • Polled TXOP generation at AP is optional Adrian Stephens, Intel

  7. Classification • Required only to provide 802.1D priority tag assignment • Transport provided for classifier element • Informative description provided for a layer above the MAC Adrian Stephens, Intel

  8. The End Adrian Stephens, Intel
