Abstract: A data analytical engine receives packets from a number of different network interface devices. The data is a replica of part or all of transmit or receive packets processed in the network interface device. A learning algorithm is applied to data from said different network interface devices and it is determined if an alert is to be generated.

Abstract: A data processing system is provided. A host processing device supports a host transport engine operable to establish a first transport stream over a network with a remote peer. Device hardware comprises a device transport engine. The device transport engine is configured to monitor the first transport stream to determine a state of the first transport stream and in response to an indication from the host processing device perform transport processing of the first transport stream.

Abstract: A data processing system comprising: a host computer system supporting a software entity and a receive queue for the software entity; a network interface device having a controller unit configured to provide a data port for receiving data packets from a network and a data bus interface for connection to a host computer system, the network interface device being connected to the host computer system by means of the data bus interface; and an accelerator module arranged between the controller unit and a network and having a first medium access controller for connection to the network and a second medium access controller coupled to the data port of the controller unit, the accelerator module being configured to: on behalf of the software entity, process incoming data packets received from the network in one or more streams associated with a first set of one or more network endpoints; encapsulate data resulting from said processing in network data packets directed to the software entity; and deliver the network data packets to the data port of the controller unit so as to cause the network data packets to be written to the receive queue of the software entity.
