Abstract: A data processing system being configured to select between different hardware resources for the running of an application configured for the sending and receiving of data over a network. The selection of hardware resources may be between resources on the network interface device, and hardware resources on the host. The selection of hardware resources may be between first and second hardware resources on the network interface device. An API is provided in the data processing system that responds to requests from the application irrespective of the hardware on which the application is executing.

Abstract: A network interface device having an FPGA for providing an FPGA application. A first interface between a host computing device and the FPGA application is provided, allowing the FPGA application to make use of data-path operations provided by a transport engine on the network interface device, as well as communicate with the host. The FPGA application sends and receives data with the host via a memory that is memory mapped to a shared memory location in the host computing device, whilst the transport engine sends and receives data packets with the host via a second memory. A second interface is provided to interface the FPGA application and transport engine with the network, wherein the second interface is configured to back-pressure the transport engine.

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 network interface device is assigned a maximum extent-of-search. A hash function is applied to the header information of each incoming packet, to generate a hash code for the packet. The hash code designates a particular subset of the table within which the particular header information should be found, and an iterative search is made within that subset. If the search locates a matching entry before the search limit is exceeded, then the incoming data packet is delivered to the receive queue identified in the matching entry. But if the search reaches the search limit before a matching entry is located, then device delivers the packet to a default queue, such as a kernel queue, in the host computer system. The kernel is then responsible for delivering the packet to the correct endpoint.

Abstract: A logic device and method are provided for intercepting a data flow from a network source to a network destination. A data store holds a set of compliance rules and corresponding actions. A packet inspector is configured to inspect the intercepted data flow and identify from the data store a compliance rule associated with the inspected data flow. A packet filter is configured to, when the data flow is identified as being associated with a compliance rule, carry out an action with respect to the data flow corresponding to the compliance rule.
