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 software networking arrangement for operation in a data processing system comprising an OS being operable in: a first mode in which it performs protocol processing of a flow of traffic data and then passes the protocol processed data to a NIC for transmission; and a second mode in which it does not perform protocol processing, the OS being arranged to, on entering the second mode, transmit a message to the NIC indicating that the NIC is to perform protocol processing of the flow of traffic data; the software networking arrangement comprising: a protocol processing entity; and a driver for a NIC configured to receive said message from the OS and in response thereto, configure the protocol processing entity to perform transport-level protocol processing of the flow of traffic data received from an application within the context of that application and then pass the protocol processed data to the NIC.

Abstract: Roughly described: a network interface device has an interface. The interface is coupled to first network interface device circuitry, host interface circuitry and host offload circuitry. The host interface circuitry is configured to interface to a host device and has a scheduler configured to schedule providing and/or receiving of data to/from the host device. The interface is configured to allow at least one of: data to be provided to said host interface circuitry from at least one of said first network device interface circuitry and said host offload circuitry; and data to be provided from said host interface circuitry to at least one of said first network interface device circuitry and said host offload circuitry.

Abstract: A data processing system comprising: an operating system providing an application programming interface; an application supported by the operating system and operable to make calls to the application programming interface; an intercept library configured to intercept calls of a predetermined set of call types made by the application to the application programming interface; and a configuration data structure defining at least one action to be performed for each of a plurality of sequences of one or more calls having predefined characteristics, the one or more calls being of the predetermined set of call types; wherein the intercept library is configured to, on intercepting a sequence of one or more calls defined in the configuration data structure, perform the corresponding action(s) defined by the configuration data structure.

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 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.

Abstract: Roughly described, a network interface device is assigned a maximum extent-of-search. A hash function is applied to the header information of each incoming packet, to generate a hash code for the packet. The hash code designates a particular subset of the table within which the particular header information should be found, and an iterative search is made within that subset. If the search locates a matching entry before the search limit is exceeded, then the incoming data packet is delivered to the receive queue identified in the matching entry. But if the search reaches the search limit before a matching entry is located, then device delivers the packet to a default queue, such as a kernel queue, in the host computer system. The kernel is then responsible for delivering the packet to the correct endpoint.
Abstract translation: 大致描述了网络接口设备被分配最大的搜索范围。 散列函数被应用于每个输入分组的报头信息，以产生分组的哈希码。 哈希代码指定在其中应当找到特定头部信息的表的特定子集，并且在该子集内进行迭代搜索。 如果搜索在超出搜索限制之前找到匹配的条目，则传入数据包将被传递到匹配条目中标识的接收队列。 但是，如果在找到匹配的条目之前搜索达到搜索限制，则设备会将数据包传递到主机系统中的默认队列（如内核队列）。 然后，内核负责将数据包传递到正确的端点。
