Re: Network traffic simulator

If this is a one time thing, you're probably better off renting an Ixia or Spirent device. If you find yourself doing this a few times a year, might be worth investing in one. Not only for just throughput testing but spamming packets for testing DoS, testing convergence times of routing

I've used Spirent in the past. They do a hardware option, as well as a VM. Lots of things supported like BGP, and PPP. Regards, Dave On 24 May 2016 at 21:31, Jason Lixfeld wrote: > I’m in the process of building a box using MoonGen [1] and a supported > Intel 82599 6

Hi,I am looking to validate the performance specs of a core router. I am looking for a network traffic simulator which can simulate 40 gbps of traffic. I am looking for a simulator with sfp+ ports. I am interested in any input as to brands to look at, build one myself etc. Thanks,Mitchell 

Re: LACP Frames / Level3 Transport

Yes. Many vendors are using l2vpn/pseudo-wire services of one sort or another to provide circuits and most do not transport LACP by default. LACP uses slow-protocols address: https://wiki.wireshark.org/LinkAggregationControlProtocol If they are using ALU gear, they can enable this using the

Hi John, I have been working with Courtney Smith and a fix has been implemented. Apparently a bunch of new Level(3) peering circuits were turned up on 5/15 and that's when the chronic packet loss problem started for our users. I have not been informed of the details as to what was causing such

Thanks all..! I just had to sit and trace all the cables to make sure the tx/rx lined up for the right circuits as well as hitting the right patch panel ports. Once all that got aligned nicely things started working magically.  thanks,-nevin On Tuesday, May 24, 2016 2:49 AM, Eygene

Re: Question on peering strategies

I disagree somewhat, without a view of how you are being hijacked there often can be no remediation. Yahoo for example provides no cloud services so you can't purchase a view of their routing by getting a VM. Jared Mauch > On May 24, 2016, at 12:29 PM, Max Tulyev wrote:

Re: Question on peering strategies

Typically you would use a private VLAN between you and another participant in order to connect to them separately from the public peering VLAN. You would do this instead of a PNI in a situation where you’re in a different building from the other participant making a direct fibre more expensive
