4. Implementation proposal
Standards to be supported
CAPWAP RFC ( RFC 5415) -
IEEE Binding ( RFC 5416)

5. High level user stories
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.
As an administrator I would like to have a single application using which I could control and provision my network end to end ( Wireless access + Wired )

6. 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
