    摘要： In an input/output virtualization-enabled computing environment, a device, method, and system for securely handling virtual function driver communications with a physical function driver of a computing device includes maintaining communication profiles for virtual function drivers and applying the communication profiles to communications from the virtual function drivers to the physical function driver, to determine whether the communications present a security and/or performance condition. The device, method and system may disable a virtual function driver if a security and/or performance condition is detected.

    摘要： A method, apparatus, system, and computer readable medium are disclosed. In one embodiment the method includes detecting a virtual machine (VM) attempting to communicate with a device coupled to a computer system using a first software plug-in interface that is incompatible with the device. The method continues by temporarily removing the VM from controlling system. Then the first software plug-in interface in the VM is replaced with a second software plug-in interface, which is compatible with the device, without the knowledge of the VM. Then control is returned to the VM and the VM is allowed to resume the communication attempt with the device using the second software plug-in interface.

    摘要： In an embodiment, an apparatus is provided that may include circuitry to be comprised in a platform. The circuitry may be to determine, at least in part, at least one virtual machine (VM) resident in the platform to be assigned to process, at least in part, at least one packet. The circuitry may determine, at least in part, the at least one VM based at least in part upon (1) comparison, at least in part, of at least one destination of the at least one packet to at least one predetermined destination, and (2) at least one value based at least in part upon both at least one port associated with the at least one packet and at least one source of the at least one packet. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

    摘要： According to some embodiments, protocol control information is speculatively pre-fetched from an external memory unit. For example, a processing engine may speculate, based on a receive packet, a connection that will subsequently have a send packet to be processed in accordance with a protocol. The processing engine may also dynamically calculate a time when protocol control information, associated with the speculated connection, is to be pre-fetched from an external memory unit (e.g., the time may be calculated in accordance with an estimated processing time associated with the receive packet and an estimated latency time associated with pre-fetching the protocol control information from the external memory unit). The protocol control information associated with the connection may then be pre-fetched from the external memory unit in accordance with the dynamically calculated time.
