Flow control and the receive window
See how the receiver sets a limit on the sender, and why a small window cripples a long, fast link. About 12 minutes.
A connection has a 64 KB receive window and a 200 ms round trip. About what is its maximum throughput?
- AAbout 2.6 Mbps
- B64 Mbps
- CThe full rate of the link
Show the answer
About 2.6 Mbps. 65,536 bytes × 8 ÷ 0.2 s = 2.6 Mbps, whatever the link's rate.
