Hmmm. Good point. Perhaps the Internet traffic gets only a small share of
the link capacity and the rest is reserved for corporate clients' VPN
traffic etc. I was thinking more along the lines of corporate SLAs, not for

What products/services do you use for traffic generation? Also what
sort of testing methodology do you use? As for random probes that
certainly seems like a nice feature.

As I gather, there is a mix of answers, ranging from building the resources
according to requirements and HOPE for the best to use of arguably
sophisticated tools and perhaps sharing the results with the legal
department.
I would be particularly interested in hearing the service providers'
