PANA-Ping-Request/Answer could have a separate state machine. That way, the transitions in that state machine does not interfere with transitions in the other state machine that deals with processing any other PANA message. This scheme prevents any special case handling to be part of the protocol specification. Your suggestion below works too I believe. Though I lean towards the above suggestion, given that it does not special case one type of message in the spec. I remember once mentioning use of a separate state machine for pings.
