Theory: Short Summary
The Maximum bandwidth can be calculated as follows:
where RWIN is the TCP Receive Window and RTT is the round-trip time for the path. The Max TCP Window size in the absence of TCP window scale option is 65,535 bytes.Example: Max Bandwidth = 65535 bytes / 0.220 s = 297886.36 bytes/s * 8 = 2.383 Mbit/s.
We multiply the Byte per second times 8 to get the Bit per second rate. Over a single TCP connection between those endpoints, the tested Bandwidth will be restricted to 2.376 Mbit/s even if the contracted Bandwidth is greater.

Famous quotes containing the words short and/or summary:
“Language was not powerful enough to describe the infant phenomenon. “I’ll tell you what, sir,” he said; “the talent of this child is not to be imagined. She must be seen, sir—seen—to be ever so faintly appreciated.”... The infant phenomenon, though of short stature, had a comparatively aged countenance, and had moreover been precisely the same age—not perhaps to the full extent of the memory of the oldest inhabitant, but certainly for five good years.”
—Charles Dickens (1812–1870)
“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
—George Gordon Noel Byron (1788–1824)
