I am developing a distributed application, which I'm currently running on a cluster of Ubuntu VMs over LAN. I'd like to evaluate the performance of my application over WAN. So I decided to use Netem and tc to add network delay, etc. . My problem is that I don't know which values to set for latency, jitter, packet loss, etc. which represents a generalized WAN for creating meaningful evaluation results that supports my claim that the application has been evaluated over WAN? I've not found so far a resource indicating that, forwarding me to such a resource would be also very welcomed. Thank you very much.
Can I use pfsense or m0n0wall to simulate WAN-like packet loss, jitter, duplication, and reordering?
I see questions looking for dedicated solutions like: What tool(s) can I use to simulate a WAN for HTTP traffic?
But, I'd like to know if it can be done with a regular router distro too. Ideally as a transparent Ethernet bridge, not an actual router.
Thank you
I'm using iperf to test the bandwidth on my network. I have a few questions: 1. I'm running this command on the client: "iperft -c -u -b 400m" and it successfully runs. I'm running the command every few seconds. I've found that if I run them too closely to each other, the first packet loses a good chunk of data (20% - 30%). However, if I wait 2-3 seconds before consecutive commands, the first packet usually has no loss. Is this an issue with iperf and my PC, as opposed to a problem with iperf and my network? 2. I'm getting jitter in the range of 0.079 ms and 0.536 ms. Is this normal and/or acceptable? What is an appropriate amount of jitter for a network to support VOIP, in your opinion? Thanks, in advance, for your help! - Charles
I need to track Jitter and Packet Loss over a MPLS line. What's the most accurate way to capture this information without interfering with the data being sent back and forth?
Is SmokePing the best tool for the job or is there something better?
