take a look at Tobias' smokeping - veeeerrry coool:

	graphs round-trip-time and its variance and packet loss in a
	single comprehensive graph.

also, check out my mrtg-ping-probe and mrtg-misc-probe at

	mrtg-ping-probe uses the system's native ping to generate
	round-trip-time and packet loss graphs.  to be used with mrtg.

	mrtg-misc-probe has a section to query a ntp server to graph
	the delay that ntp calculates.  you will need ntp servers at
	both ends of the network connection you want to monitor.

Hope this helps
