I test access multiplexers and would like to create a network of guest hosts, each with their own IP. The purpose of this is to try to congest multiplexer-under-test with TCP traffic. There will be a simulated PC for each of the modems connected to a multiplexer-under-test that supports between modems.
I would then like to set up a packet TCP generator or an FTP server on the uplink of the multiplexer, where the guest hosts would then simultaneously download files from the server.
Brian Linkletter November 20, at 6: In my opinion, you need a hypervisor like Xen, KVM, of VMWare or you can use Linux containers maybe use Dockerwhich use less systme resources than full VMs and may allow you to run more virtual test nodes per host machine.
Set up your VMs and connect them all to the 10G port. Even then, I would recommend other tools like chef or puppet or use shell scripts instead of a network simulator for your test system because it seems you will need more functionality related to virtual server setup automation instead of simulating different network topologies.
Lisa November 20, at I mostly use python for automation scripting. Or do I use tools like Jmeter?
Brian Linkletter November 20, at You will have to do some testing, I think. You can create a set of virtual servers that all connect to the external Ethernet interface on the host machine. You can create a custom service type that supports starting an FTP client and then running some download commands.
When you save the network scenario, you can re-load it at a later date to run the same test again. But, I do not know what kind of performance you will get.
Adam Peace December 6, at 4: Is there any free network simulator software that I can use as a tool to develop and demonstrate a working IPS within a simulation? I appreciate any advice you give me!
Brian Linkletter December 8, at 3: What protocols do you intend to use in your solution? If you can describe your needs in terms of the technology you need to emulate, you may be more successful in finding answers.
Brian Kemal December 12, at 2: We are working on implementing communication network testbed for a smart grid system. Can you please recommend an emulation tool with realistic performance and which is not complicated to configure?Phalcon is an open source web framework delivered as a C extension for the PHP language providing high performance and lower resource consumption.
