Abstract: Some embodiments of the invention provide a method for configuring a physical network card or physical network controller (pNIC) to provide flow processing offload (FPO) for a host computer connected to the pNIC. The host computers host a set of compute nodes in a virtual network. The set of compute nodes are each associated with a set of interfaces that are each assigned a locally-unique virtual port identifier (VPID) by a flow processing and action generator. The pNIC includes a set of interfaces that are assigned physical port identifiers (PPIDs) by the pNIC. The method includes providing the pNIC with a set of mappings between VPIDs and PPIDs. The method also includes sending updates to the mappings as compute nodes migrate, connect to different interfaces of the pNIC, are assigned different VPIDs, etc. In some embodiments, the flow processing and action generator executes on processing units of the host computer, while in other embodiments, the flow processing and action generator executes on a set of processing units of a pNIC that includes flow processing hardware and a set of programmable processing units.

Abstract: Some embodiments of the invention provide a method for providing flow processing offload (FPO) for a host computer at a physical network interface card (pNIC) connected to the host computer. A set of compute nodes executing on the host computer are each associated with a set of interfaces that are each assigned a locally-unique virtual port identifier (VPID) by a flow processing and action generator. The pNIC includes a set of interfaces that are assigned physical port identifiers (PPIDs) by the pNIC. The method includes receiving a data message at an interface of the pNIC and matching the data message to a stored flow entry that specifies a destination using a VPID. The method also includes identifying, using the VPID, a PPID as a destination of the received data message by performing a lookup in a mapping table storing a set of VPIDs and a corresponding set of PPIDs and forwarding the data message to an interface of the pNIC associated with the identified PPID.
