It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.11. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <stuart.kerry@philips.com> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee.org>. W. Steven Conner, Intel Corp., et al. Donald Eastlake 3rd, Motorola

Comments on Current Structure June 2006 doc.: IEEE 802.11-06/826r3 July 2006 Comments on Current Structure Currently, all WLAN Mesh protocol descriptions are in a single major section of the document (11A) Some of the functions described here are closely related to similar functions in the base standard E.g., new versions of discovery, association, link security, beaconing, synchronization, power save functions, which are currently specified in the base std for BSS and IBSS modes E.g., new MAC protocols that build on and are tightly coupled to EDCA in the base standard (MDA and CCF) Other functions described here are unique to mesh and only loosely coupled to the base standard E.g. path selection and forwarding, mesh interworking, congestion control are new functions not included in the base standard W.

June 2006 doc.: IEEE 802.11-06/826r3 July 2006 Document Organization Conventions Typically Used by Other TG Amendments Functionality that is closely related to existing functions in the base standard integrated into existing sections Functionality that is new/unique to the TG goes in its own major section of the document Advantages of this approach Consistency with the base standard and other TG amendments May be helpful for non-TGs reviewers to understand what parts of the draft are closely related to existing functions/other amendments W. Steven Conner, Intel Corp., et al. Donald Eastlake 3rd, Motorola

Other considerations for Document Structure June 2006 doc.: IEEE 802.11-06/826r3 July 2006 Other considerations for Document Structure The IEEE Standards Style Manual limits the subclause hierarchy to a maximum of 5 levels E.g. 1.2.3.4.5 is acceptable 1.2.3.4.5.6 is not acceptable Many clauses in D0.02 exceed this limit W.
