Question : How to access to bandwith statistics from kernel space?

[Martin Houry]

I have made some research and I could't find a library  who can give
me interfaces's statistics like max/min/average bandwidth, jitter, ...

Do you know a way to do this?

Thank you
Martin

What problem are you trying to solve from within the kernel with those
statistics?

You probably should look at how the various TCP congestion routines work.

Question : How to access to bandwith statistics from kernel space?

I'm trying to improve the algorithm of load balancing in the NFS4.1
Client of the session trunking implementation (to do multipath).

If I get bandwith (and other criteria like TCP congestion as you
said), I would be able to estimate the state of each path in real
time. So I could send the NFS's operations on the best path. All this
in order to improve performance when you have path with variant
performance.

Thanks for your help :)
