When Chariot was a NetIQ product i= t seemed to generate regular spikes as the algorithm tried to correct the t= otal throughput over a time interval. It's not a problem for slow data rates but when testing near the limit of a= circuit's capacity the spikes could sometimes overflow the buffers of Ethe= rnet media converters and give false results.

Ixchariot calculates for you the MOS score and, depending fro= m the NIC, can also push close to 1 Gig of traffic. For larger bandwidth te= sts (I believe 6-7 Gig) and fast re-route testing (ms failover) we use ixia= hardware.
