1. Introduction 1. Introduction
This document defines the state machines for Protocol Carrying This document defines the state machines for Protocol Carrying
Authentication for Network Access (PANA) [RFC5191]. There are state Authentication for Network Access (PANA) [RFC5191]. There are state
machines for the PANA client (PaC) and for the PANA Authentication machines for the PANA client (PaC) and for the PANA Authentication
Agent (PAA). Each state machine is specified through a set of Agent (PAA). Each state machine is specified through a set of
variables, procedures and a state transition table. variables, procedures and a state transition table. The state
machines and associated models described in this document are
informative only. Implementations may achieve similar results using
different models and/or methods.
A PANA protocol execution consists of several exchanges to carry A PANA protocol execution consists of several exchanges to carry
authentication information. Specifically, EAP PDUs are transported authentication information. Specifically, EAP PDUs are transported
inside PANA PDUs between PaC and PAA, that is PANA represents a lower inside PANA PDUs between PaC and PAA, that is PANA represents a lower
layer for EAP protocol. Thus, a PANA state machine bases its layer for EAP protocol. Thus, a PANA state machine bases its
execution on an EAP state machine execution and vice versa. Thus execution on an EAP state machine execution and vice versa. Thus
this document also shows for each of PaC and PAA an interface between this document also shows for each of PaC and PAA an interface between
an EAP state machine and a PANA state machine and how this interface an EAP state machine and a PANA state machine and how this interface
allows to exchange information between them. Thanks to this allows to exchange information between them. Thanks to this
interface, a PANA state machine can be informed about several events interface, a PANA state machine can be informed about several events
