Implementation proposal Standards to be supported CAPWAP RFC ( RFC 5415) - IEEE 802.11 Binding ( RFC 5416)

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 )

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

High Level message flow Targeted for initial release B SAL å CAPWAP Access point CAPWAP plugin SAL Application Discovery Join Inventory Update Configuration /policy action Configuration /policy action

High Level message flow with CAPWAP and Openflow Potential future B SAL å CAPWAP Openflow Access point CAPWAP plugin SAL Application Discovery Join Inventory Update Flow control Flow control

Potential risks Selecting Right DTLS implementation
