I've used JDSU and Exfo test sets for the generation of the traffic, both of which are getting better at simulating 'real' traffic via tcp sessions and voip/video simulation using UDP. They include the ability to measure round-trip delay, jitter, packetloss, etc. At very least, you could use them to generate a few different streams of traffic, each with a different DSCP/802.1p marking. Then do your classification etc on your edge and so on. I've even toyed with free generation tools like IPERF and NUTTCP which run on a PC/server, which will obviously limit the amount of traffic you can generate (I can get ~700Mbps from a laptop).
If you don't trust the test-set's values for latency, jitter, etc., some platforms support ITU-T 1731 and 802.1ag standards for connectivity fault management and measurement, which let you do end-to-end measurement. Cisco of course calls it IPSLA, but other vendors have implemented same (MRV OS904 CPE device, among others). I think the MX-series just added those protocols in 9.5-ish as well, so you can do measurements just across the core, etc. David 2009/10/7 Ivan c <ivann...@gmail.com>: > Hi, > > I am looking into what systems are available for testing and > verification of QoS behaviour and performance between sites on a > provider WAN.
