Hello,
Don't know how its is working, it maybe the link limit from mininet!
But openvswitch does not support meters!
you can use this softwswitch that supports it
https://github.com/CPqD/ofsoftswitch13
You can see that ovs doe snot support any meters here in this link:

And that the switch i said before does!

Hope that helps you.
