    Abstract: A rule engine receives data flows. The data flows are between a network and an application. The rule engine determines data flow information and in dependence on the information performs an action with respect to said flow. A controller provides control information to the rule engine to define one or more actions. The communications between said rule engine and said controller are secure.

    Abstract: Roughly described, a header processing engine for a network interface device has a header recognizer to parse the headers of a data packet stored at a buffer to identify the type and position of each header in the packet; a constructor unit; and a processor including an execution pipeline. The header recognizer is configured to, for each header: select in dependence on the header type commands stored at a command memory; and form one or more messages for the constructor unit identifying the selected commands and the position of the header in the data packet. The commands selected for the packet headers are collectively such as to, if executed by the constructor unit, cause the constructor unit to generate a data structure which operates to cause the processor to process of the packet headers without accessing the data packet at the buffer.

    Abstract: A data processing system and method are provided. A host computing device comprises at least one processor. A network interface device is arranged to couple the host computing device to a network. The network interface device comprises a buffer for receiving data for transmission from the host computing device. The processor is configured to execute instructions to transfer the data for transmission to the buffer. The data processing system further comprises an indicator store configured to store an indication that at least some of the data for transmission has been transferred to the buffer wherein the indication is associated with a descriptor pointing to the buffer.

    Abstract: A network interface device includes an interface configured to receive data packets for a host processing device and an engine supporting a network interface device component of an application that is provided on the host processing device. In response to receiving data packets for the application, the engine is configured to cause at least some of the data packets to be available to the component of the application, to cause the data packets to be delivered to a protocol stack of the host processing device, and to receive control information associated the data packets from the protocol stack of the host processing device. The interface is configured to output an acknowledgement message comprising the control information.
