I use

sudo mn --link tc,bw=10,delay=10m

and it gives errors

*** Adding links: (10.00Mbit 10ms delay) *** Error: RTNETLINK answers: No such file or directory (10.00Mbit 10ms delay) *** Error: RTNETLINK answers: No such file or directory (h1, s1) (10.00Mbit 10ms delay) *** Error: RTNETLINK answers: No such file or directory (10.00Mbit 10ms delay) *** Error: RTNETLINK answers: No such file or directory (h2, s1)

Is this the mininet problem or my operate system problem ?
