Re: [Nanog-futures] New Membership-WG Draft
I suspect the board will set some kind of a discount for students. Personally, I would support a very large discount for full time students. agreed It still escapes me as to why a student should get any financial stimulus to be a member of an organization that will help him/her with their professional development. I'm always learning and I don't always have a lot of money, so I should get a break too. - Brian J.

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!!!

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.

I don't have this problem thankfully but I know many do and it is probably the major reason why v6 adoption is slow. Many networks needs money invested to upgrade for v6 readiness. The message is do it now before the costs dramatically increase. The problem with C-level folks is not they don't want to do it but there is no financial incentive for them to do it, if there is no direct benefit to drive revenue then why put the money? The barrier for v6 is not technical it is purely financial, some understand the economics and some don't. Finance people usually think that the longer you can put off expenses the better it looks for your balance sheet. This is really the crux of the problem. Zaid

Why would someone with clue want to calm the hysteria? I've had hysterical moments dealing with v6 transitions. Come to and end? Nah. Be a really rough ride? Unless things change, probably. Wait, if there's no transition to ipv6, the internet will end? And all our piracy and information control problems will end with it? That's just grand! Quick, pass a law against ipv6 adoption! Mandatory death penalty! Why didn't anyone think of this sooner? (NOW who says you can't put the genie back in the bottle? Stupid eggheads! :)

Re: Interesting IPv6 viral video
Wait till CNN/FOX etc makes this a big issue and claim the internet is going to come to an end press frenzy in the '93 '94 era was what forced the ipv6 design, to solve the problem. and it did, the press shut up. problem is it did not solve the needed technical problems. but that is only pain for us, who cares? randy
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).

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.

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.
