               SLAPP: Secure Light Access Point Protocol

Abstract

   The Control and Provisioning of Wireless Access Points (CAPWAP)
   problem statement describes a problem that needs to be addressed
   before a wireless LAN (WLAN) network designer can construct a
   solution composed of Wireless Termination Points (WTP) and Access
   Controllers (AC) from multiple, different vendors.  One of the
   primary goals is to find a solution that solves the interoperability
   between the two classes of devices (WTPs and ACs) that then enables
   an AC from one vendor to control and manage a WTP from another.

   In this document, we present a protocol that forms the common
   technology-independent framework and the ability to negotiate and
   add, on top of this framework, a control protocol that contains a
   technology-dependent component to arrive at a complete solution.  We
   have also presented two such control protocols -- an 802.11 Control
   protocol, and another, more generic image download protocol, in this
   document.

   Even though the text in this document is written to specifically
   address the problem stated in RFC 3990, the solution can be applied
   to any problem that has a controller (equivalent to the AC) managing
   one or more network elements (equivalent to the WTP).

IESG Note

   This RFC documents the SLAPP protocol as it was when submitted to the
   IETF as a basis for further work in the CAPWAP Working Group, and
   therefore it may resemble the CAPWAP protocol specification in RFC
   5415 as well as other IETF work.  This RFC is being published solely
   for the historical record.  The protocol described in this RFC has
   not been thoroughly reviewed and may contain errors and omissions.

   RFC 5415 documents the standards track solution for the CAPWAP
   Working Group and obsoletes any and all mechanisms defined in this
   RFC.  This RFC is not a candidate for any level of Internet Standard
   and should not be used as a basis for any sort of Internet
   deployment.
