Re: Ethernet performance tests
Hi all, do you know if I will be able to use two different vendors to execute these tests ? For example, let's say that I have one JDSU unit in the side A and a EXFO unit in the side B. Will these tests work ? If not, is there a way to execute these tests having two different vendors ?

Re: Ethernet performance tests
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. Ciao On 10/27/10, Diogo Montagner diogo.montag...@gmail.com wrote: Hello everyone!!!

RE: Ethernet performance tests
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.

Re: Ethernet performance tests
I tried the ultra high throughput script just for fun to see how much I could push ... I got a solid 920 mbps stream for the entire time I run the test (circa 30-60 seconds) with not spikes. The hardware in that case were two IBM hs-20 blades with broadcom chipsets. I said for fun because if we use ixchariot for throughput tests usually is just for small T1 sites (max 3xT1) so I have never seen the issue you mentioned. Usually on the same T1, we fill the data VLAN with traffic and then we run x voice pairs on the voice vlan to validate QoS (MOS score).

many switch and routing vendors provide such functionality in their os. this data can then be collected via SNMP, stored for reports and forwarded as events, when necessary. tate On 10/27/2010 7:32 PM, Diogo Montagner wrote: Hello everyone, I am looking for performance test methodology for ethernet-based circuits.

RE: Ethernet performance tests
For comissioning testing, you can use a hardware packet generator to send packets to an Ethernet demarcation with a MAC-swap loopback, and analyse the returned traffic. For ongoing performance monitoring, having Y.1731 capable CPE is highly desirable.

There's a few rack systems you can use which can either generate packets or provide a home base loop system for the end node test sets depending on your requirements. Jack
