  • Virtualizing the operation of intelligent network interface circuitry
    Patent number: 8686838
    Abstract: The present invention is in the field of virtualization of Network Interface Cards and Controllers (NIC) that connect to for example a host computer that can have multiple functions and OS's (referred to as guest functions and guest-OS's) running on it simultaneously and, in particular, relates to the virtualization of the operation of a single NIC such that it can be used simultaneously by multiple guests in such a manner that memory references due to the network traffic originating from and destined to a particular guest is kept separate from other network traffic, and that allows the Media Access Controller (MAC) within the NIC to operate such that it only accepts network packets that are destined to one of the guest-functions or guest-OS's, and the MAC is not required to operate in promiscuous mode where it accepts all incoming packets in order to implement the virtualization features.

  • Protocol offload in intelligent network adaptor, including application level signalling
    Patent number: 8589587
    Abstract: A host is coupled to a network via an intelligent network adaptor. The host is executing an application configured to receive application data from a peer via the network and the intelligent network adaptor using a stateful connection according to a connection-oriented protocol. The intelligent network adaptor performs protocol processing of the connection. Application data is copied from host memory not configured for access by the application (possibly OS-associated host memory) to host memory associated with the application (application-associated host memory). The application data is received from the peer by the intelligent network adaptor and copied to host memory not configured for access by the application. The operating system selectively provides, to the intelligent network adaptor, information of the memory associated with the application.
