Question

Consider bandwidth of line is 100 Mbps and sequence number of field consists 32 bits on a TCP machine. How much time it will take to cover all possible sequence numbers? ________________ sec (integer value only).

I think you are right. Please provide the answer. Here is the question and its answer, which I think is wrong. http://www.techtud.com/example/consider-bandwidth-line-100-mbps-and-sequence

Answer 1

As Tcp is byte streamed protocol it means we numbered each byte transmitted.

Here Sequence field is 32 bits, So we can uniquely numbered or identify =2³² Bytes

Bandwidth is 100 Mbps.

Means 100 Mb   data is transmitted in 1 sec

(10⁸ )/8 byte     data is transmitted in 1 sec

1 byte data is transmitted in 8/10⁸ sec

2³² byte data is transmitted in  (2³² *8)/10⁸ sec=2³⁵/10⁸ seconds

Solving it you will get 343.597 seconds
