| 发明名称 | Managing data flows in overlay networks | ||
| 摘要 | Embodiments relate to managing data flows at a virtual forwarding element. A system for managing data flows is provided. The system includes a network interface card (NIC) attached to or integrated with a host. The system is configured to perform a method. The method receives a plurality of data flows from a virtual forwarding element executing in the host. The plurality of data flows originate from a plurality of virtual machines executing in the host. Each of the plurality of data flows carries a different network identifier and a different tunnel header. The method maps, by the NIC, a plurality of tunnels defined by the plurality of tunnel headers to the plurality of data flows using the plurality of network identifiers. The method sends the plurality of data flows out of the host through the plurality of tunnels. | ||

| 主权项 | 1. A computer system for managing data flows, the system comprising: a network interface card (NIC) attached to or integrated with a host, the system configured to perform a method comprising: receiving a plurality of data flows from a virtual forwarding element executing in the host, the plurality of data flows originating from a plurality of virtual machines executing in the host, each of the plurality of data flows carrying a different network identifier and a different tunnel header; mapping, by the NIC, a plurality of tunnels defined by the plurality of tunnel headers to the plurality of data flows using the plurality of network identifiers; and sending the plurality of data flows out of the host through the plurality of tunnels. | ||
