Abstract

Some embodiments provide a physical forwarding element that dynamically adjusts the number of flows allowed in a flow table cache. In adjusting, the physical forwarding element initially sets the maximum number of flows allowed in the cache. From the flow table cache, the physical forwarding then iterates through the set maximum number of flows and records the length of time it took to iterate through the flows. Based on the duration, the physical forwarding element then automatically adjusts the size of the flow table cache by increasing or decreasing the number of flows allowed in the cache. Alternatively, the physical forwarding element may choose to keep the cache size the same based on the duration.
