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 system has data capture devices collecting data from different points in a network. The captured data is written to a data store and is directed to an output. The data from the different data capture devices can be delivered to a data analytics device. As long as the data analytics device is able to keep pace with the data that is directed to the output, that data is used by the analytics device. If the analytics device is not able to keep pace, the data written to the data store is retrieved and is used until the analytics device has caught up.
Abstract translation: 系统具有从网络中的不同点收集数据的数据捕获设备。 所捕获的数据被写入数据存储并被引导到输出。 来自不同数据采集设备的数据可以传送到数据分析设备。 只要数据分析设备能够跟上定向到输出的数据，该数据就被分析设备使用。 如果分析设备无法保持速度，则会检索写入数据存储区的数据，直到分析设备赶上。

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.
