Hello Yiannis,
I was really confusing the subjects. Now I understood the parameter priority.
Just another question. I think that in the old version of FlowVisor I
could configure a Bandwidth parameter. I was thinking that priority
parameter has replaced it. Is there some parameter to add a simple QoS
mechanism like bandwidth in FlowVisor?
Thank you.
My best regards.

Hi Luciano,
I think you are confusing priority of a flow-entry with QoS-related
priority.
Priority will define which flow-entry the incoming packets will match. In
your case, traffic that goes to tp_dst=5060 matches both slices definition,
but it belongs (and therefore controlled) by the one with highest priority.
It doesn't have any impact on the rates these flows will achieve.
For this you might want to look at min-rate queues :

Hello,
I´d like a little help to know if I understood correctly the use of
priority parameter on a FlowSpace.
I created a topology and divided it in two slices: voice and data. After
this I configured two FlowSpaces on each switch following the examples
below:
fvctl addFlowSpace <MAC> 10000 "tp_dst=5060" "Slice:voice=4"
fvctl addFlowSpace <MAC> 1 any "Slice:data=4"
When I was reading "man fvctl" I understood that the priority parameter
determines the priority of the flow. However, during my tests with Iperf I
have got better results with the data´s slice.
Am I using correctly the parameter priority?
I used mininet + NOX + flowvisor in my tests.
Best regards.
