tcp frame

Question

Suppose a server transmits one frame of a video every second, and the client starts playing the video at one frame per second as soon as the first frame arrives. Suppose the first ten frames arrive at times 0, 1.2, 1.99, 4.17, 4.01, 5.03, 8.05, 7.50, 8.90, 8.99, all in seconds. Which frames reach the client too late for playout?

(A) 7

(B) 3

(C) 6

(D) 5

Answer 1

For every second one frame reaches the client.

Time(seconds)	Frame No.	Arrive at client	Diff in delay to reach client
0	0	0	0
1	1	1.2	0.2
2	2	1.99	0
3	3	4.17	1.17
4	4	4.01	0.01
5	5	5.03	0.03
6	6	8.05	2.05
7	7	7.50	0.50
8	8	8.90	0.90
9	9	8.99	0.99

If we consider frame no from (0-9) then 6th frame is having more delay.

If we consider frame no from (1-10) then 7th frame is having more delay.

Hence it depends on which frame no consideration.Either from (0-9) or (1-10) (in question it is not clear about frame no)

Comments

why dont u consider 6th frame.it is too late compared to 3rd one.??

Shoukd be both then.

out of all frames reach the client which one is having more delay.Then 6th is more delay then 3rd .
