Sent: Mar 27, 2009 3:33 PM I believe there is an ITU standard for testing that could be looked at, but if you went with the same test gear that SPs use to test their circuits, I think you would be safe. Hence my mention of JDSU, but I could also add Agilent (more engineering focused), Anritsu, EXFO, Fluke (more enterprise focused), and SR Telecom.

If you're turning up a 10 GigE circuit, as a customer I would be asking for that circuit to be tested with some modern tools such as the JDSU T-BERD. For the price you're probably paying, it's probably not unreasonable to have it as part of the turn-up fee.
What is it then that one would classify as an 'industry standard' test for turning up 100Mb-1Gb connections over optical? Is there an industry approved standard application in which the results can be backed up by the "big" SP's? Something that can be passed to the client that explains that "even though your VPN gateway is doing 20Mbps, we can get 856Mbps over the connection without it". (My chosen setup is two FBSD boxes that boot/run from removable media into 2-4GB of RAM using Iperf and/or the 'netrate' tools). Steve ps. I've toyed with small deployments of MPLS VPNs and SP owned CE with encrypted tunnels, but the hardware to do such at any scale is out of reach for us at this point. The theory in practise is fantastic though ;) Sent via BlackBerry from T-Mobile

Owamp?
owamp is a latency measurement tool. While we find it invaluable, I'm not sure how it fits in here. We use iperf on high-performance systems with a lot of tuning and Myricom 10GE cards to test 10 Gig circuits (10GE or OC-192). No particular endorsement of Myricom. We also qualified Chelsio. At the time we tested, TSO on the Chelsios caused some problems when the other end was a Myricom, but TSO is easily turned off. -- R.
