Abstract
Some embodiments provide a novel method for offloading firewall operations from a host computer executing a set of one or more virtual machines (VMs) to a physical network interface card (PNIC) connected to the host computer. The method configures, on the PNIC, a first firewall to determine actions to perform on flows associated with the set of VMs, and to offload processing of the flows to a flow-cache second firewall of the PNIC. The method configures, on the PNIC, the flow-cache second firewall to process a first set of flows based on a first set of actions determined by the first firewall, and to offload processing of a second set of flows to an embedded hardware switch of the PNIC. The method configures, on the PNIC, the embedded hardware switch to process the second set of flows based on a second set of actions determined by the first firewall.
