I have used BRIX active measurement for IP for many years, but here is a
link that describes BRIX in conjunction with ADVA for Ethernet probes.
There is an article in IEEE Communications Magazine circa 2004-2005 by AT&T
researchers describing their roll your own active measurement system,
theoretical assumptions, and theory of probe data collection.
