Re: [eap] Ordered delivery of EAP messages
Assuming that per session there can only be one outstanding request for an
EAP conversation >since the conversation depends on acks from its peer to
continue.
ACK/NAK protocols can have more than one packet in flight, if you take false
retransmissions into account.
Then if new messages and retries are sent out in any order on the wire they
would either be detected by either side as duplicates or processed and
handled accordingly regardless of order of receipt.
Both EAP and RADIUS do not detect duplicates arriving out of order; they
depend on the underlying lower layer to provide in-order delivery so as to
enable duplicate detection.
