Is there a tool to test connection stability?

Question

Computer networks

Is there any utility that would run on two PCs (server and client) and start loading and testing the channel with various methods to find out how stable the connection is? To show the number of packet losses, whether there were drops in speed, etc. under windows.

Answer 1

iperf
Enable display of errors in connection properties: dumpcap here (bundled with Wireshark sniffer). tcpdump PS: I've been working with this for a long time , but I can't find the distribution.

Answer 2

I am using PingPlotter . There is a version on the torrent for the budget conscious. It's almost the same as WinMTR, just a nice visualization.
You say strange things about stability. If you pour a lot of traffic, then the ping will inevitably increase. And the more traffic, the more errors and more ping. So by casting traffic, you can only measure the width of the channel.
And for stability, you need to ping indefinitely. The longer, the more accurate the result. Days, weeks. Statistics on large numbers (frequency and time) will allow us to judge stability in general. And if something starts to fail, even if the brakes were a few seconds, then you need to look after the factfor drawdowns in the chart. That is, it’s not that you poured traffic, checked stability, calmed down and use it. No not like this. PingPlotter always works and pings not only the target machine, but also intermediate nodes, as well as more distant or neighboring nodes (for completeness in case of problems), and remembers the entire chronology. Even if there was a failure while you were sleeping, you will still know about it. Otherwise, in the event of a short failure, after which everything was quickly restored, you will not be able to find out its cause, and if you were not a witness, you will not know about the failure at all.

Answer 3

try WinMTR
