Patent number: 12231339Abstract: Methods and apparatus for extending OpenvSwitch (OVS) megaflow offloads to hardware to address hardware pipeline limitations. Under a method implemented on a compute platform including a Network Interface Controller (NIC) having one or more ports and running software including OVS software and a Linux operating system having a kernel including a TC-flower module and a NIC driver a new megaflow is created with a mask in the OVS software employing a subset of microflow fields for a packet. The microflow fields and the megaflow mask is sent to the NIC driver. A new megaflow is implemented in the NIC driver employing a subset of the microflow fields and the NIC driver creates a new hardware flow on the NIC employing a packet match scheme using all the microflow fields. The NIC also programs a NIC hardware pipeline with the new hardware flow using a match scheme that may depend on the available hardware resources, such as the size of a TCAM.Type: GrantFiled: November 9, 2020Date of Patent: February 18, 2025Assignee: Intel CorporationInventors: Namrata Limaye, Venkata Suresh Kumar Paruchuri, Sridhar Samudrala, Kiran Patil

Patent number: 10135687Abstract: A virtual switch connected to at least one virtual machine of multiple virtual machines communicatively connected through an overlay network, receives a data packet, each of the virtual machines configured within a separate one of multiple virtual groups in the overlay network, the data packet comprising a packet header comprising at least one address. The virtual switch receives a virtual group identifier for the at least one address from at least one address resolution service returning the virtual group identifier and a resolved address for the at least one address, in response to an address resolution request for the at least one address. The virtual switch sends the data packet through the virtual switch to the resolved address only if the virtual group identifier is allowed according to a filtering policy applied by the virtual switch for a particular virtual group identified by the virtual group identifier.Type: GrantFiled: January 6, 2014Date of Patent: November 20, 2018Assignee: Lenovo Enterprise Solutions (Singapore) Pte.
