How to measure the speed of the Internet on all nodes from point A to point B?

Question

Computer networks

Please tell me if there is such a service or software, in which you can determine not the overall speed of the Internet, but on all nodes, how can tracert only show not the ping over the nodes, but the speed? I need to understand where the connection speed is reset, on the highways or at the provider.

Answer 1

What is "internet speed at the node"?
The maximum that you can measure is the bandwidth of the channel between two nodes, for example, a certain server and your computer. At the same time, both nodes must have software that allows this to be done, the same iperf. Naturally, no provider will install such software on routers. In addition, the speed may depend on the current congestion of the channels, a specific route, protocol, provider restrictions, etc.

Answer 2

You do not have access to go to intermediate hosts and test something from them somewhere.

Answer 3

No way.
WINMTR is in your hands, run it for an hour and then see where the delays are.
It is not realistic to test the access speed on each transition.
