Usage guidelines
To protect against replay attacks, the sender places a unique sequence number in each RSVP message
that contains authentication information. The sender monotonically increases the value of the sequence
number each time it sends an RSVP message. If the sequence number of a received message is in the
specified authentication window size, the receiver accepts the message. Otherwise, the receiver discards
the message.
