In open-loop control, policies are applied to __________

Remove after congestion occurs Remove after sometime Prevent before congestion occurs Prevent before sending packets

Retransmission of packets must not be done when _______

Packet is lost Packet is corrupted Packet is needed Packet is error-free

In Go-Back-N window, when the timer of the packet times out, several packets have to be resent even some may have arrived safe. Whereas in Selective Repeat window, the sender resends ___________

Packet which are not lost Only those packets which are lost or corrupted Packet from starting All the packets

Discarding policy is mainly done by _______

Sender Receiver Router Switch
