[Bloat] Measuring latency-under-load consistently

[Fred Baker]

At the risk of sounding like someone mentioning a product, let me mention a product. This assumes, of course, that you're using Cisco equipment. But it allows you to measure delay (how long does it take to get from here to there), jitter (first derivative of delay/dt), and packet loss.
