The state machine measures the incidental roundtrip delay jitter and oscillator frequency wander and determines the best poll interval using a heuristic algorithm. Ordinarily, and in most operating environments, the state machine will start with 64s intervals and eventually increase in steps to 1024s. A small amount of random variation is introduced in order to avoid bunching at the servers. In addition, should a server become unreachable for some time, the poll interval is increased in steps to 1024s in order to reduce network overhead." -todd _______________________________________________ chat mailing list [email protected] Archived: http://news.gmane.org/gmane.network.freenet.general Unsubscribe at http://dodo.freenetproject.org/cgi-bin/mailman/listinfo/chat Or mailto:[email protected]?subject=unsubscribe
