Question

True or false. Please circle the answer.
(a) (1 point) True or false? A TCP connection has only one rwnd between the two ends.

(b) (1 point) True or false? The size of the TCP rwnd never changes throughout the duration of the connection

(c) (1 point) True or false? Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over a TCP connection to Host B. In this same segment the acknowledgment number is necessarily 42.

(d) (1 point) True or false? TCP is an SR protocol.

(e) (1 point) True or false? TCP carries IP information in segment headers.

(f) (1 point) True or false? UDP guarantees delivery time. (g) (1 point) True or false? TCP slow start and congestion avoidance avoids congesting the underlying network.

Explanation / Answer

a) True, yes only one receiving window is there between two ends in a TCP connection

b) False, The size of the receiving window is dynamic in order to control congestion.

c) False. The acknowledgement number is not related with the sequence number. It indicates the next sequence number A is expecting from B.

d) True, TCP uses sliding window protocol

e) True, Source and destination address is used.

f) False, There is no guarantee of delivery

g) True, They are used for congestion avoidance.
