Suppose that the current replay window spans from $111$ to $430.$

$($a$)$ If the next incoming authenticated packet has sequence number $99,$ what will

the receiver do with the packet, and what will be the parameters of the window

after that?

$($b$)$ If instead the next incoming authenticated packet has sequence number $420,$

what will the receiver do with the packet, and what will be the parameters of

the window after that?

$($c$)$ If instead the next incoming authenticated packet has sequence number $566,$

what will the receiver do with the packet, and what will be the parameters of
