CAPWAP Proposal

Name

CAPWAP interface support

Repo Name

Description

As a baby step for achieving the goal of Unified management of wired and wireless networks using right abstractions ,we would like to propose the implementation of "Control And Provisioning of Wireless Access Points (CAPWAP) Protocol" as one of the south bound interface.

User Stories

• As an administrator I would like to have a single application using which I could control provision & apply policies in my network with an end to end view ( Wireless access + Wired )

     # As an administrator I would like to have a single application 
     using which I could  control  my network with an end to end view  
     # As an administrator I would like to have a single application 
     using which I could   provision  my network with an end to end view  
     # As an administrator I would like to have a single application 
     using which I could   apply policies  in my network with an end to end view  

• As an administrator I would like provide service discovering capabilities for my access points. I would like to do this using CAPWAP open standard.
• As an administrator I would like to authorize and authenticate my access points and allow them to join to my administrative domain. I would like to do this using CAPWAP open standard.
• As an administrator I would like to configure and apply policy to the access points in my administrative domain . I would like to do this using CAPWAP open standard.
• As an administrator I would like to get statistics and reporting from my access points. I would like to do this using CAPWAP open standard.

Standards to be supported

• CAPWAP RFC ( RFC 5415) -
• IEEE 802.11 Binding ( RFC 5416)

Scope

• South Bound MD-SAL Plugin for CAPWAP
• CAPWAP Protocol library ( CAPWAP RFC 5415)
• CAPWAP 802.11 bindings" ( CAPWAP RFC 5416)
• "Unified test Application for CAPWAP and the 802.11 bindings
• Local Mac with local bridged- In the initial version Local Map Support will be provided . There will not be split mac support in the initial version.

• From RFC 5415

  ...........The Local MAC mode of operation allows for the data frames to be
  either locally bridged or tunneled as 802.3 frames. ...................

  .........................When Local Bridging is used, the WTP does not tunnel user
  traffic to the AC; all user traffic is locally bridged.  ..................

Software Components

• Connection Handler

     Handles UDP & DTLS connections

• CAPWAP Protocol Library

    Implements CAPWAP Protocol

• MD-SAL CAPWAP Plugin

    South bound ODL plugin

• Inventory Manager

    Database for Access Points

• North Bound Sample application

    Example application which could demonstrate  e2e network abstraction
