  1. State Machine for PANA(draft-ohba-pana-statemachine-00.txt) Yoshihiro Ohba, Victor Fajardo, Rafael Marin Lopez IETF60 PANA WG

  2. Motivations • As a companion document to the PANA base protocol document • As an implementation scheme • Insight on PANA internals • Insight on PANA and EAP Interface • Insight host system interface considerations • Detailed Schematic:http://www.toshiba.com/tari/pana/pana-statemachine.html IETF60 PANA WG

  5. Next Steps • Feedback from implementors, verification of the state machine • Accommodate EP interface • Migrated to an informational document IETF60 PANA WG
