Question

In a TCP connection, the window size fluctuates between 60,000 bytes and 30,000 bytes. If the average RTT is 30 ms, what is the throughput of the connection?

Answer 1

The throughput of a TCP connection fluctuates between 1 MB/s and 2 MB/s when the window size fluctuates between 60,000 bytes and 30,000 bytes, with an average RTT of 30 ms.

Step-by-step explanation:

The throughput of a TCP connection can be calculated using the formula: throughput = (window size) / (RTT). In this case, the window size fluctuates between 60,000 bytes and 30,000 bytes, and the average RTT is 30 ms.

Using the maximum window size of 60,000 bytes and the average RTT of 30 ms:

Throughput = (60,000 bytes) / (30 ms) = 2000 bytes/ms = 2,000,000 bytes/s = 2 MB/s

Using the minimum window size of 30,000 bytes and the average RTT of 30 ms:

Throughput = (30,000 bytes) / (30 ms) = 1000 bytes/ms = 1,000,000 bytes/s = 1 MB/s

Therefore, the throughput of the TCP connection fluctuates between 1 MB/s and 2 MB/s.
