My favorite tool for assessing delay distribution and loss over time
is Tobi Oetiker's (of MRTG fame) SmokePing (http://www.smokeping.org/).
As input, it can use various types of measurements - ping RTT/loss
measurement in the simplest case, but also Cisco SAA (now called IP
SLA) measurements, or various other types of probes such as HTTP or
DNS requests.
The nice thing is the way it presents the time distributions
graphically. The graphs also include loss rates. Check out the
"demo" part of Tobi's webpage.
