  4. Implementation proposal • Standards to be supported • CAPWAP RFC ( RFC 5415) - • IEEE 802.11 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

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

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

  9. Potential risks • Selecting Right DTLS implementation
