Class ConnThrottler

java.lang.Object

net.i2p.i2ptunnel.ConnThrottler

class ConnThrottler
extends Object

Count how often something happens with a particular peer and all peers. This offers basic DOS protection but is not a complete solution. This is a little different from the one in streaming, in that the ban time is different from the check time, and we keep a separate map of throttled peers with individual time stamps. The streaming version is lightweight but "sloppy" since it uses a single time bucket for all.

Since:

0.9.9
