Traffic generator for SDN testing

[rabad]

Hi

I a newbie to this forum... I'm search for traffic generator for SDN, can someone recommend a tool to use?

thanks

what is your budget?
Where do you need it  cloud?


Ixia has a IxNetwork—Software Defined Network (SDN) Test Solution
runs about 30K+

budget is very low , its for sdn controller.

Where do you need it  cloud?

AWS has IXIA instanced you can build and use pretty cheap

That will probably be the way to go, renting instead of buying. PacketStorm is another product to consider: and you would also have the question of whether or not you want just raw traffic blasted away or if you want to have traffic emulation or simulation, where the product generates very high loads of legitimate traffic.

On that note, a poor man's route is to generate your own traffic, use WireShark to capture it, then to use open source tools for PCAP playback. I've done that for simulating traffic from a manufacturing line that couldn't be connected to the same network that a traffic analysis tool was running on.

If this is for stress testing, the cheapest route may be an open source tool that just blasts away. If this is for proof-of-concept testing to be sure that communications get from A to B all right, then a PCAP replay of normal traffic could do the job.

What are the requirements? Are you just testing throughput, do you need to test specific traffic like VoIP, or something else? IXIA can do just about anything, but I find it kind of hard to use for simple testing. If you just want some throughput testing you can just use Iperf. There is also TRex which is an open source traffic generator. I have not used it, but I have heard it is pretty good.

what I'm looking for is a traffic generator that I can load to my Ubuntu VM, I tried Ostinato and traffic is not going through mininet topology in my controller, is there a traffic gen that can be use with mininet?

[Otanx]

Never used mininet, but their getting started guide covers using iPerf with mininet.

mininet has only limited protocols

Perhaps a more complete description of what you're seeking can help. What are the protocols you need to simulate? Is there a use case for your business that you need to investigate, or is this labbing something you're researching? More detail can help us zero in on the right answer for your issue.
