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

[Martin Houry]

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 :)
