TCP Types

Question 1

What does TCP stand for?

Answer 1

Transmission Control Protocol

Question 2

True or False: Fast TCP is designed to improve TCP performance in high-speed networks.

Answer 2

True

Question 3

What is the primary goal of Fast TCP?

Answer 3

To enhance throughput while maintaining fairness among flows.

Question 4

Fill in the blank: Fast TCP uses a more aggressive __________ mechanism compared to traditional TCP.

Answer 4

congestion control

Question 5

Which of the following is a characteristic of Fast TCP? A) Slow start B) Aggressive throughput increase C) Low latency D) All of the above

Answer 5

D) All of the above

Question 6

What type of networks does Fast TCP primarily target?

Answer 6

High-bandwidth, high-latency networks

Question 7

True or False: Fast TCP guarantees complete fairness among all connections.

Answer 7

False

Question 8

What is the role of the congestion window in Fast TCP?

Answer 8

It controls the amount of data that can be sent before receiving an acknowledgment.

Question 9

Short answer: How does Fast TCP differ from standard TCP in terms of congestion avoidance?

Answer 9

Fast TCP employs a more responsive approach to adjust the congestion window based on network conditions.

Question 10

What is the ‘Fast Recovery’ phase in TCP?

Answer 10

A phase that allows TCP to recover quickly from packet loss without entering the slow start phase.

Question 11

Fill in the blank: Fast TCP aims to minimize __________ during data transmission.

Answer 11

packet loss

Question 12

Which congestion control algorithm is often associated with Fast TCP?

Answer 12

TCP Vegas

Question 13

True or False: Fast TCP can be implemented over both IPv4 and IPv6.

Answer 13

True

Question 14

What is the significance of round-trip time (RTT) in Fast TCP?

Answer 14

RTT is used to adjust the congestion window and to optimize throughput.

Question 15

Short answer: Why is Fast TCP considered more suitable for multimedia applications?

Answer 15

Because it can provide higher throughput and lower latency, which are essential for real-time data delivery.

Question 16

What does the term ‘fairness’ refer to in the context of TCP flows?

Answer 16

The equitable distribution of bandwidth among multiple TCP connections.

Question 17

Fill in the blank: Fast TCP incorporates __________ to detect and respond to congestion more quickly.

Answer 17

delay-based algorithms

Question 18

Which of the following is NOT a benefit of Fast TCP? A) Higher throughput B) Reduced latency C) Guaranteed delivery D) Better congestion control

Answer 18

C) Guaranteed delivery

Question 19

True or False: Fast TCP can negatively impact the performance of traditional TCP flows.

Answer 19

True

Question 20

What does ‘TCP fairness’ imply about the behavior of different TCP types in a shared network?

Answer 20

It implies that different TCP types should not monopolize the available bandwidth.

Question 21

Short answer: Describe a potential drawback of using Fast TCP.

Answer 21

It may lead to unfair bandwidth allocation among different types of TCP flows.

Question 22

Fill in the blank: Fast TCP adjusts its sending rate based on __________ measurements.

Answer 22

RTT

Question 23

What is the main challenge that Fast TCP addresses in modern networks?

Answer 23

The inefficiency of traditional TCP in utilizing available bandwidth effectively.

Question 24

True or False: Fast TCP is only beneficial in wired networks.

Answer 24

False

Question 25

What is the primary mechanism that Fast TCP uses to increase its congestion window?

Answer 25

It uses a more aggressive approach to increase the congestion window based on RTT estimates.
