Etherate : the beginning of an Open Aurora Tango test (L2 tester)…

For those of you which perform some Aurora Tango tests (BERT, RFC 2544) you may know that a couple of these testers are really expensive !

During my readings of mailing-lists such as cisco-nsp or others, someone posts an URL to a really awesome Linux program : etherate. With modern CPU platform you are able to supply a throughput until 1G, and this program give you the possibility to test your L2 circuits.

You can do some tests by using it such as :
