Question

Consider the following statements about the timeout value used in TCP.
(i) The timeout value is set to the RTT(Round Trip Time) measured during TCP connection establishment for the entire duration of the connection.
(ii) Appropriate RTT estimation algorithm is used to set the timeout value of a TCP connection.
(iii) Timeout values set to twice the propagation delay form the sender to the receiver.
Which of the following choices hold?

• A. (i),(ii) and (iii) are false
• B. (i) and (ii) are false, but (iii) is true
• C. (i) and (iii) are false, but (ii) is true
• D. (i) is false, but (ii) and (iii) are true

Answer 1

The correct option is C (i) and (iii) are false, but (ii) is true

Appropriate RTT estimation algorithm is used to set the timeout value of a TCP connection.
Hence, the other statements regarding timeout values are incorrect.
