Claim Text:
1. For a managed forwarding element that processes packets in a host machine according to a set of flow entries stored in a set of forwarding tables, a method comprising: receiving a packet from an end machine that operates on the host machine; when the packet matches a template flow entry with a set of data fields unpopulated, sending the template flow entry to a flow entry generating module that operates on the host machine; receiving a new flow entry with the set of data fields populated from the flow entry generating module; and storing the new flow entry received from the flow entry generating module in a forwarding table, wherein the new flow entry has a higher priority than the template flow entry such that subsequent packets are processed according to the new flow entry rather than the template flow entry without sending the template flow entry to the flow entry generating module.
