  1. Standardizing for QoS(QoS Questions) Bob O’Hara Albert Young Dan Nessett Bruce Kendall Bofu Chen Bob O’Hara, et al.

  2. How Do We Proceed? • Ensure there is a common understanding of just what “QoS” means • Identify requirements against which alternatives may be judged Bob O’Hara, et al.

  3. Some Questions • What is QoS? • Is it an action, behavior, or something else? • How is QoS measured? • Can it be measured? • What SAP primitives are used to request/control QoS? • What protocols are on the other side of this SAP? • What are the parameters that cross this SAP? • How would current IETF developments work with this SAP? • Integrated Services? • Differentiated Services? Bob O’Hara, et al.

  4. Some Questions • What upper layer protocols support/require QoS from the Data Link/MAC layer? • What about 802.1p? • How is QoS supported by existing OS APIs? • What OS APIs are proposed to be added to support QoS at the MAC layer? • Who are we expecting to add these APIs? • OS vendors? • 802.11 developers? Bob O’Hara, et al.

  5. Some Requirements • How can alternative proposals be evaluated? • No simulation data • No definitive impact statement on existing equipment • No apparent demand for QoS in LAN space, let alone WLAN • No defined interfaces • What RFCs require/support the proposed services? • What is the mapping to upper layer protocols? • What are the concrete benefits provided by the proposed services? Bob O’Hara, et al.
