Re: 802.16 Medium Access Control Task Group INVITATION TO CONTRIBUTE – Session #5, Document 80216-99_14.pdf Abstract This MAC proposal is based upon DOCSIS 1.1 (Data Over Cable Service Interface Specifications). Modifications to this existing standard are included to support the requirements defined by the 802.16 Working Group for BWA networks. This is a collaborative effort of the above listed people. Purpose The author desires that the 802.16 working group incorporate all or part of the proposal into the 802.16.1 standard. Notice This document has been prepared to assist the IEEE 802.16. 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 contributors reserve the right to add, amend or withdraw material contained herein. Release The contributors acknowledges and accepts that this contribution may be made public by 802.16. IEEE Patent The contributors are familiar with the IEEE Patent Policy, which is set forth in the IEEE-SA Standards Board Bylaws <http:// Policy standards.ieee.org/guidesbylaws> and includes the statement: “IEEE standards may include the known use of patent(s), including patent applications, if there is technical justification in the opinion of the standards-developing committee and provided the IEEE receives assurance from the patent holder that it will license applicants under reasonable terms and conditions for the purpose of implementing the standard.” Portions of this document are reprinted with permission from Cable Television Laboratories, Inc. 1 1999-12-24 IEEE 802.16mc-00/01 Document Overview This submission was generated from the DOCSIS 1.1 source FrameMaker files. Annex L is provided that lists the significant changes to the DOCSIS MAC to support the BWA MAC. It is strongly recommended the reader begin by reading that Annex. In an effort to make the document easier to read, the following conventions were used: • The paragraph numbering follows the 802.16.1 Air Interface Standard outline. • The original DOCSIS paragraph have minimal changes. In places where substantive changes are made, the changed text is red and a change bar is placed at the outer edge of the text. Changes related to naming (CMTS to BS) are not marked in this way. • A list of modifications is provided which provides a quick hyper-text link to all modified paragraphs. • All indexes are hyper-text linked, allowing quick browsing when reading the PDF format. The Appendixes are considered part of the MAC proposal, and contain information that is in addition to what is contained the main proposal. • The first Annex describes the significant areas within the BWA MAC that differ from the DOCSIS MAC. • The other Annexes are included simply on an informative basis; these Annexes are not officially part of this MAC proposal. The Annexes contain material that was considered by the co-contributors to have possible merit and which should be evaluated further. This material could not be adequately analyzed or discussed in the short amount of time that was available. 2 IEEE 802.16mc-00/01 1999-12-24 Modifications MAC Reference Model

    IMPROVING DOCSIS RELIABILITY DOCSIS™ RELIABILITY = INCREASED REVENUE Data-over-cable System Interface Specification (DOCSIS) is the vehicle for cable operators to obtain immediate revenue generating opportunities such as Broadband Data, Voice over IP, IP Video-on-Demand, and countless emerging IP-based technologies. These growth channels rely on cable operators obtaining and retaining subscribers. Subscriber satisfaction with new services is a direct function of DOCSIS network reliability. Improving DOCSIS network reliability requires new skills and new test equipment, in addition to the skills and test equipment we possess as an industry today.

It will allow architecture in which the conventional operators to deliver economic IP video traffic Modular-CMTS architecture is replaced by a over DOCSIS infrastructure. hybrid architecture consisting of an integrated CMTS and DOCSIS External Physical INTRODUCTION Interface (DEPI) or MPEG Edge QAMs. This paper/presentation will demonstrate the MSOs are considering IP-video and IP effectiveness of DIBA, discuss how operators Television (IPTV) to supplement their current can evolve their infrastructure to implement digital video delivery. IP-based video enables DIBA, discuss alternative bypass new video sources (the Internet) and new encapsulation protocols to tunnel traffic to video destinations (subscriber IPTV playback either DEPI or MPEG Edge QAMs, and devices). outline the economic advantages of DIBA Of course, such a transition to IPTV migration. It will explain how DIBA removes requires significant additional downstream the boundaries of delivering video using a M- DOCSIS® bandwidth.
