Consider a TCP connection with a 1ms RTT in which the sender has 50,000 bytes of data to send and there are no losses and no congestion. The receiver has an initial advertised window of 10,000 bytes and reads 2,000 bytes of data once every two seconds. What is the advertised window in bytes after one second

Advertised window in bytes after one second = 0 bytes.

Explanation:

Given:

Sender bytes = 50,000 bytes

Receiver's initial advertised window = 10,000 bytes

Read rate = 2,000 bytes / per 2 second

Find:

Advertised window in bytes after one second = ?

Computation:

We know that, 10,000 bytes have been buffered in receiving initial advertised window.

Receiver read 2,000 bytes in every 2 second.

So, receiver will not able to read anything in 1 second.

Therefore,

Advertised window in bytes after one second = 0 bytes.
