Month 1998 doc. : IEEE 802. 11 -00/066 Standardizing for Qo. S (Qo. S Questions) Bob O’Hara Albert Young Dan Nessett Bruce Kendall Bofu Chen Standardizing for Qo. S 1 John Doe, His Company

May 2000 doc. : IEEE 802. 11 -00/066 How Do We Proceed? • Ensure there is a common understanding of just what “Qo. S” means • Identify requirements against which alternatives may be judged Standardizing for Qo. S 2 Bob O’Hara, et al.

May 2000 doc. : IEEE 802. 11 -00/066 Some Questions • What is Qo. S? – Is it an action, behavior, or something else? • How is Qo. S measured? – Can it be measured? • What SAP primitives are used to request/control Qo. S? – 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? Standardizing for Qo. S 3 Bob O’Hara, et al.

May 2000 doc. : IEEE 802. 11 -00/066 Some Questions • What upper layer protocols support/require Qo. S from the Data Link/MAC layer? • What about 802. 1 p? • How is Qo. S supported by existing OS APIs? • What OS APIs are proposed to be added to support Qo. S at the MAC layer? – Who are we expecting to add these APIs? • OS vendors? • 802. 11 developers? Standardizing for Qo. S 4 Bob O’Hara, et al.

May 2000 doc. : IEEE 802. 11 -00/066 Some Requirements • How can alternative proposals be evaluated? – No simulation data – No definitive impact statement on existing equipment – No apparent demand for Qo. S 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? Standardizing for Qo. S 5 Bob O’Hara, et al.
