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 system is arranged to receive data which is written to a data store by a writer. A controller is able to read data from the data store. That controller is able to control the rate at which data is read from the data store with respect to the rate at which data is written to the data store. A query function receives a stream of said data substantially in real time and when said stream of data is unavailable in real time, the query function is able to subsequently obtain that unavailable data from said data store.

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: 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: A network interface device, said network interface device has a data transmission path configured to receive data for transmission. The data for transmission is to be sent over a network by the network interface device. A monitor is configured to monitor the data transmission path to determine if an underrun condition is associated with the data transmission path. If so, an indication is included in the transmitted data packet.
