RE: Ethernet performance tests

[Jonathon Exley <Jonathon.Exley () kordia co nz>]

How smooth is the Ixchariot data stream? When Chariot was a NetIQ product it seemed to generate regular spikes as the 
algorithm tried to correct the total 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 Ethernet media converters and give false results.

Hi Diogo

We use ixchariot endpoints installed on linux laptops to test sites for voice readiness. Ixchariot calculates for you 
the MOS score and, depending from the NIC, can also push close to 1 Gig of traffic. For larger bandwidth tests (I 
believe 6-7 Gig) and fast re-route testing (ms failover) we use ixia hardware.
