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 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, incoming data packets are delivered by the NIC directly to at least two user level endpoints. In an aspect, only filters that cannot be ambiguous are created in the NIC. In another aspect, the NIC maintains a filter table supporting direct delivery of incoming unicast and multicast data packets to one user level endpoint. Additional requests to join the same multicast group cause replacement of the NIC filter with one in the kernel. In another aspect, a NIC has limited capacity to maintain multicast group memberships. In response to a new multicast filter request, the kernel establishes it in the NIC only if the NIC still has sufficient capacity; otherwise it is established in the kernel.
Abstract translation: 粗略描述，传入数据分组由NIC直接传递到至少两个用户级端点。 在一方面，仅在NIC中创建不能模糊的过滤器。 另一方面，NIC维护一个过滤表，该过滤表支持将一个单播和多播数据包直接传送到一个用户级端点。 加入同一组播组的其他请求会导致内核中的NIC过滤器的更换。 另一方面，NIC具有维持多播组成员身份的能力有限。 响应于新的多播过滤器请求，内核仅在NIC仍然具有足够的容量时才在NIC中建立它; 否则它在内核中建立。
