For comissioning testing, you can use a hardware packet generator to send packets to an Ethernet demarcation with a MAC-swap loopback, and analyse the returned traffic. For ongoing performance monitoring, having Y.1731 capable CPE is highly desirable.

These ethernet circuits can be: dark-fiber, l2circuit (martini), l2vpn (kompella), vpls or ng-vpls. Sometimes, the ethernet circuit can be a mix of these technologies, like below: CPE <-> metro-e <-> l2circuit <-> l2vpn <-> l2circuit <-> metro-e <-> CPE The goal is verify the performance end-to-end. I am looking for tools that can check at least the following parameters: - loss - latency - jitter - bandwidth - out-of-order delivery At this moment I have been used IPerf to achieve these results. But I would like to check if there is some test devices that can be used in situations like that to verify the ethernet-based circuit performance. The objective of these tests is to verify the signed SLAs of each circuit before the customer start to use it. I checked all MEF specifications and I only find something related to performance for Circuit Emulation over Metro-E (which is not my case). Appreciate your comments.
