Abstract: A method and data processing system are provided. The data processing system comprises an application associated with a plurality of sockets and a sub-system for making data available to the application via the plurality of sockets. The sub-system is configured to provide in response to a request from the application: an indication of events that have occurred on one or more of the plurality of sockets; and an indication of an order in which the events should be processed.

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 network interface device for connection between a network and a data processing system, the network interface device comprising: a plurality of ports for receiving data packets directed to the data processing system. An interface services the ports in a predetermined order and writes the data packets to buffers of a common memory. Each buffer is part of one of a set of linked logical sequence of buffers forming virtual queues in the common memory. Each virtual queue is associated with a port. A memory manager selects buffers of the common memory so as to cause the interface to populate the plurality of virtual queues with data packets.

Abstract: A method for controlling the processing of data in a data processor such that the data processor is connectable to a further device over a data link. The method comprising the steps of receiving data at an element of the data processor and if a set interval has elapsed following the receipt of the data, determining whether processing of the received data in accordance with a data transfer protocol has begun, and, if it has not, triggering such processing of the received data by a protocol processing element. The method then senses conditions pertaining to the data link and sets the interval in dependence on the sensed conditions.

Abstract: A method is disclosed for bridging between a first data link carrying data units of a first data protocol and a second data link for carrying data units of a second protocol by means of a bridging device. This method may comprise receiving by means of a first interface entity data units of a first protocol, and storing those data units in the memory. Then, accessing by means of a protocol processing entity the protocol data of data units stored in the memory and thereby performing protocol processing for those data units under the first protocol. The method also accesses by means of a second interface entity the traffic data of data units stored in the memory and thereby transmits that traffic data over the second data link in data units of the second data protocol.
