? It seems you are discussing the behaviour of the clocks, not of the network. (the network has no frequency). His simulator works with real clocks which have exactly the behaviour you describe. Now it may be that the network model is not the best ( random "long" delays in one way trip time due to network overload). > > Dr Mills modelling also has this problem. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
