HotSwapping

Hot Swapping

FlowScale provides the option of reactively adjusting the flows in an OpenFlow switch should some ports receive significantly higher traffic.  An attempt will be make to balance the load on every outgoing port.  One of the bundles in FlowScale (edu.iu.incntre.flowscaleflowupdate) will run in the background continuously.  On a configurable time interval a process will run that will calculate the amount of traffic each port received in the time interval.  FlowScale will then make a decision on what flows will need to be offloaded and what ports will receive the new flows.

If the traffic to the OpenFlow switch is unpredictable.  Hot Swapping will help balance the traffic on the ports available.
