Consider a long-lived TCP session with an end-to-end bandwidth of 1Gbps. The session starts with a sequence number of 1234. The minimum time (in seconds, rounded to the closet integer) before this sequence number can be used again is _________.
The solution given for above question was : [(2^32)*8]/(10^9) = 34.3597 sec
But what I think it should be : [(2^32)208]/(10^9) = 687.194 sec
I have multiplied it by 20 because minimum size of TCP packet is 20Bytes.
Please help me to clear the confusion which answer should be right and why. If there is another answer for the above question please let us know.
