Abstract: A network interface device having a hardware module comprising a plurality of processing units. Each of the plurality of processing units is associated with its own at least one predefined operation. At a compile time, the hardware module is configured by arranging at least some of the plurality of processing units to perform their respective at least one operation with respect to a data packet in a certain order so as to perform a function with respect to that data packet. A compiler is provide to assign different processing stages to each processing unit. A controller is provided to switch between different processing circuitry on the fly so that one processing circuitry may be used whilst another is being compiled.

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.

Abstract: A network interface device comprises a streaming data processing path comprising a first data processing engine and hubs. A first scheduler associated with a first hub controls an output of data by the first hub to the first data processing engine and a second scheduler associated with a second hub controls an output of data by the second hub. The first hub is arranged upstream of the first data processing engine on the data processing path and is configured to receive data from a first upstream data path entity and from a first data processing entity implemented in programmable circuitry via a data ingress interface of the first hub. The first data processing engine is configured to receive data from the first hub, process the received data and output the processed data to the second hub arranged downstream of first data processing engine.

Abstract: A network interface device has a data source, a data sink and an interconnect configured to receive data from the data source and to output data to the data sink. The interconnect has a memory having memory cells. Each memory cell has a width which matches a bus segment width. The memory is configured to receive a first write output with a width corresponding to the bus segment width. The write output comprises first data to be written to a first memory cell of the memory, the first data being from the data source.

Abstract: Roughly described, a network interface device receiving data packets from a computing device for transmission onto a network, the data packets having a certain characteristic, transmits the packet only if the sending queue has authority to send packets having that characteristic. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. Authorizations can be programmed into the NIC by a kernel routine upon establishment of the transmit queue, based on the privilege level of the process for which the queue is being established. In this way, a user process can use an untrusted user-level protocol stack to initiate data transmission onto the network, while the NIC protects the remainder of the system or network from certain kinds of compromise.
