    Abstract: A logic device and method are provided for intercepting a data flow from a network source to a network destination. A data store holds a set of compliance rules and corresponding actions wherein at least one of the set of compliance rules is a temporary compliance rule valid for a predetermined period. A packet inspector is configured to inspect the intercepted data flow and identify from the data store a temporary compliance rule associated with the inspected data flow. A packet filter is configured to when the data flow is identified as being associated with the temporary compliance rule, carry out an action with respect to the data flow corresponding to the temporary compliance rule while the temporary compliance rule is valid.

    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 network interface device is provided. The network interface device comprises an input configured to receive a data frame from a network. The network interface device also comprises a timing component configured to store, for the data frame, first timing information and compensation information. The compensation information is specific to the frame. The first timing information and said compensation information representing a time when the data frame was received.

    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。

    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.
