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.

Hi Are there any best common practices for the CFM levels use Since my pure Ethernet aggregation layers are small I believe I only need two CFM levels I plan on using Level 5 between CPEs managed by us and Level 4 between Aggregation devices -that's where MPLS PWs kicks in So leaving Level 7 and Level 6 for customers and carrier-customers respectfully -would this be enough please?
I'm also interested on what's the rule of thumb for CCMs Frequency, Number of Packets, Interpacket Interval, Packet Size and Lifetime for the particular operation Thanks a lot for any inputs
