[ovs-discuss] Capacity/Quota in ovs/openflow

[Amar Padmanabhan]

Hi Peter
Thanks for the mail, we have a local controller instance that is running on the host so the sflow or periodic poll seem equivalent to me. Is there a way to do this on path?

    Amar,
    
    Open vSwitch includes sFlow / NetFlow instrumentation. Using flow data to drive your quota controller reduces the complexity of the OpenFlow rules since you no longer need granular rules to provide the traffic measurements. 
    
    The following article describes building a quota controller using sFlow:
