[ovs-discuss] How to control incoming traffic of VMs?

[cloudprovider]

Try QoS for port.


Example:
ovs-vsctl set port port1 qos=@newqos  \
-- --id=@newqos create qos type=linux-htb other-config:max-rate=5000000 queues:0=@newqueue \
-- --id=@newqueue create queue other-config:min-rate=5000000 other-config:max-rate=5000000



Thanks,
Lei Shi

Hi, Ben    "ingress_policing_rate" can only control the outgoing traffic of VMs.
I wonder how could I control the incoming traffic of VMs.  
    Thx.

 Sorry, I misunderstood this. On a virtual interface (one connected to a virtual machine), this limits the rate at which the VM is able to transmit.(outgoing traffic)
 On a physical interface, this limits the rate at which traffic is allowed into the system from the outside;(incoming traffic)
 It seems a little strange.

  Hi, Ben   In this website( http://openvswitch.org/support/config-cookbooks/qos-rate-limiting/), it says “ingress_policing_rate”: the max-rate in kbps that this VM should be allowed to send, which means the outgoing traffic.
    But in  ovs-vswitchd.conf.db(5), it says "ingress_policing_rate: Maximum rate for data received on this interface, in kbps. Data received faster than this rate isdropped. Set to 0 (the default) to disable policing.", which means the incoming traffic.
    Is there any error?

 Please stop dropping the mailing list.
 
 You can use "policing".  See ingress_policing_rate and
 ingress_policing_burst in the Interface table in
 ovs-vswitchd.conf.db(5).
