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: 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 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.
