Jitter

Jitter is a term used to mean the variation in lag over time.


In very simple terms, if you were to ping a network host 2 times and each time it responded in 100 milliseconds, we could say that its jitter is 0 ms. If instead, the 2 ping times were 75 and 100 milliseconds, we could say the jitter is 25 ms. Of course the jitter calculations performed in BZFlag are a little more complex than that, incorporating averaging and smoothing over time.


Coders interested in jitter in BZFlag's context may wish to study LagInfo.cxx from the BZ source.
