Bandwidth and Latency: It’s the Latency, Stupid (Part 2)

[In NetBITS-015, Stuart examined issues of latency and delay in typical modem-based Internet communications. This week, he discusses how bandwidth can be used more efficiently, and how it affects the overall latency of a connection.] Last week, I asked readers to imagine a world where the only network connection you can get to your house is a modem running over a telephone line at 33.6 Kbps

Bandwidth and Latency: It’s the Latency, Stupid (Part 1)

[This article originally ran in TidBITS-367 and TidBITS-368. We feel that the points it makes are important enough to present again, in an updated form, to NetBITS readers.] Years ago David Cheriton at Stanford University taught me something that seemed obvious at the time - if you have a network link with low bandwidth then it's easy to put several in parallel to make a combined link with higher bandwidth, but if you have a network link with bad latency then no amount of money can turn any number of parallel links into a combined link with good latency
