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
