12 | 12 | In this control theoretic approach, the load on VNF1 and VNF2 is monitored, and flow-forwarding decisions are made based on the load information retrieved from the hosting VMs. We will run a [http://www.geni.net/?p=3133 RINA] distributed application to get the state (load) of the VNFs to the controller VM. Once the Ryu controller has the IDS load information, it will use the Proportional Integral (PI) load balancer to balance the load across the VNF instances based on the load information. This load balancing information is then provided to the Ryu controller, which updates the !OpenFlow rules on the OVS switch to balance the load. |
