Test: Congestion Control - Question 1

In the slow-start algorithm, the size of the congestion window increases __________ until it reaches a threshold.

Detailed Solution for Test: Congestion Control - Question 1

In slow-start algorithm, the size of the congestion window increases exponentially until it reaches a threshold. When it reaches the threshold, it stops increasing and continues sending packets through the threshold window thus preventing congestion.

Test: Congestion Control - Question 2

Backpressure technique can be applied only to _______

Detailed Solution for Test: Congestion Control - Question 2

In Virtual circuit networks, each node knows the upstream node from which a flow data is coming. So, it makes possible for the congested node to track the source of the congestion and then inform that node to reduce the flow to remove congestion.

Test: Congestion Control - Question 3

Closed-Loop control mechanisms try to _________

Detailed Solution for Test: Congestion Control - Question 3

In closed loop congestion control, methods are implemented to remove congestion after it occurs. Some of the methods used are backpressure and choke packet.

Test: Congestion Control - Question 4

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 ___________

Detailed Solution for Test: Congestion Control - Question 4

In Selective Repeat, the sender side uses a searching algorithm to find the packets which need to be retransmitted based on the negative acknowledgements received and then resends only those packets thus saving bandwidth.

Test: Congestion Control - Question 5

In open-loop control, policies are applied to __________

Detailed Solution for Test: Congestion Control - Question 5

Open loop congestion control techniques are used to prevent congestion before it even happens by enforcing certain policies. Retransmission policy, window policy and acknowledgement policy are some policies that might be enforced.

Test: Congestion Control - Question 6

The packet sent by a node to the source to inform it of congestion is called _______

Detailed Solution for Test: Congestion Control - Question 6

Choke packet is sent by a node to the source to inform it of congestion. Two choke packet techniques can be used for the operation called hop-by-hop choke packet and source choke packet.

Test: Congestion Control - Question 7

The technique in which a congested node stops receiving data from the immediate upstream node or nodes is called as _______

Detailed Solution for Test: Congestion Control - Question 7

In this closed loop congestion control technique, the congested node propagates in the opposite direction of the data flow to inform the predecessor node to reduce the flow of packets. This is why this technique is called a node-to-node congestion control technique.

Test: Congestion Control - Question 8

Discarding policy is mainly done by _______

Detailed Solution for Test: Congestion Control - Question 8

The discarding policy adopted by the routers mainly states that the routers discard sensitive or corrupted packets that it receives, thus controlling the integrity of the packet flow. The discarding policy is adopted as an open loop congestion control technique.

Test: Congestion Control - Question 9

Retransmission of packets must not be done when _______

Detailed Solution for Test: Congestion Control - Question 9

Retransmission refers to the sender having to resend the packet to the receiver. It needs to be done only when some anomaly occurs with the packet like when the packet is lost or corrupted.

Test: Congestion Control - Question 10

Two broad categories of congestion control are

Detailed Solution for Test: Congestion Control - Question 10

Open loop congestion control techniques are used to prevent congestion before it even happens by enforcing certain policies. Closed loop congestion control techniques are used to treat congestion after it has happened.
