Description of Working Group:

  The original CAPWAP WG charter included drafting a problem statement
  and a taxonomy of architectures. The new charter of the CAPWAP WG
  proposes building upon the original charter and developing a CAPWAP
  protocol to provide interoperability among WLAN backend architectures.
  The intent of the CAPWAP protocol is to facilitate control, management
  and provisioning of WLAN Termination Points (WTPs) specifying the
  services, functions and resources relating to 802.11 WLAN Termination
  Points in order to allow for interoperable implementations of WTPs
  and ACs.

  The revised CAPWAP WG will reference two classes of the Centralized
  WLAN Architecture family, namely the Local MAC and the Split MAC,
  as described in the CAPWAP Architecture Taxonomy draft. The protocol
  will define the CAPWAP control plane including the primitives to
  control data access. An effective Centralized CAPWAP Architecture
  impacts how WLAN data traffic is managed over the backend network.
  This implies the abilitiy to control how data is forwarded by
  negotiating existng data encapsulation mechanisms and specifying
  data payload formats in order to ensure interoperability between
  CAPWAP vendors. No other specifications of the CAPWAP data plane
  are within the scope of this charter.

  The CAPWAP WG will strive for extensibility in the protocol design
  to favor future applicability to other access technologies, especially
  IEEE 802.16. While accommodation of any access technology other than
  IEEE 802.11 is not required for successful completion, there are clear
  deployment advantages if a wide range of access technologies are

  In summary, the primary goals of the group will be:

  1. Defining a set of Objectives based on the architecture taxonomy
  work that lists the requirements for an interoperable CAPWAP
  protocol. In addition, the WG will incorporate requirements
  derived from the inputs provided by Enterprise and (hotspot)
  Providers based on the WLAN deployment challenges addressed
  by CAPWAP architecture. This document will:

  a. include objectives to address problems described in the
  CAPWAP Problem statement document
  b. Describe each objective, its benefit to the protocol and
  how it satisfies the problem statement.
  c. Prioritize and classify the objectives into 3 categories:
  i. Mandatory and Accepted
  ii. Desirable
  iii. Rejected
  d. Undergo review in IEEE 802 as needed

  This should result in the first WG Last Call for Objectives draft.

  To avoid requirements bloat and stalemate, the WG has a
  hard deadline on the Objectives phase. The WG MUST reach WG
  consensus on the objectives draft by Feb 2005. This is for
  several reasons:
  * We must send this for review to IEEE at that time.
  * We must have a reasonably stable set of objectives
  so that candidate submissions are aware of the objectives
  to be met.

  The 2nd WG Last Call (in April) for the objectives draft is to
  ensure that the WG has consensus on any changes that may result
  from IEEE and expert review. So it is not the intention that
  the WG keeps adding new Objectives after Feb 2005.

  If the WG cannot reach consensus on the Objectives draft by the
  May 2005 milestone to the IESG, the WG will close.

  2. Evaluating a set of candidate proposals that include existing
  IETF protocols and any proposals leading to the selection of
  a protocol on which to base the CAPWAP standard.

  3. Developing a CAPWAP protocol standard that meets the Mandatory
  and Accepted objectives from the Evaluation draft and contains
  the minimal set of feature needed to control and provision
  WLAN Access Points. Specifically The CAPWAP protocol document
  will address the following considerations:
  a. Architecture
  b. Operations
  c. Security
  d. Network Management
  e. Scalability
  f. Performance

  4. A MIB Document to support the CAPWAP protocol.

  In addition, the CAPWAP WG will maintain its Liaison with the
  IEEE to ensure consistency of its work with the IEEE 802.11

  * Objectives/Criteria Document for CAPWAP protocol
  * Protocol evaluation and base protocol selection document
  * CAPWAP Protocol standard
  * MIB support standard
