State Machine for PANA(draft-ohba-pana-statemachine-00.txt)

IETF60 PANA WG

• Motivations1.As a companion document to the PANA base

protocol document2.As an implementation scheme

• Insight on PANA internals• Insight on PANA and EAP Interface• Insight host system interface

considerations

• Next Steps1. Feedback from implementors, verification of the

state machine

2. Accommodate EP interface

3. Migrated to an informational document
