摘要： Given a language with all words in a fixed length, and a set of regular expressions composed only from characters in the alphabet of the language or the “?” sign (any single character), the method of the invention defines a data structure that is used to efficiently find the set of matching regular expressions for a given query word. The method may be adjusted by appropriate selection of a control variable to vary the storage space required and the search time necessary to complete the query. Specifically, the method of the present invention provides a space versus time trade-off between the storage space required for the data structures of the present invention and the amount of time to search those data structures to determine the matching set of regular expressions.

摘要： A generic master-slave mechanism enables a single processor of a cluster of firewall processors to define the behavior of the other processors in the cluster for a specific logical connection. The cluster of firewall processors utilizes virtual adapters representing physical adapters on other processors in the firewall cluster. This virtualization allows each cluster member to act as though it is a standalone machine that owns all local IP addresses of the entire cluster. When traffic is received by a firewall processor, the firewall processor determines if there is a master associated with the logical connection for the traffic. If so, the traffic is routed to the master. If no master is associated, in an example configuration, the receiving firewall processor becomes the master. A message traffic logical connection has a single master. A master remains the master of a logical connection until the connection is terminated.

摘要： The evaluation of a policy can be delayed until all rules criteria needed for evaluation are available. Also, new types of rules criteria can be registered without requiring changes to a rules engine. A policy manager allows rules to be evaluated and decisions made at different stages of the request handling. The policy manager facilitates interaction with the rules engine until all criteria are evaluated. The policy manager also allows modules developed by third parties to provide notification when criteria can be decided and thus complete evaluation.
摘要翻译：可以推迟对政策的评估，直到评估所需的所有规则标准可用。此外，可以注册新类型的规则标准，而不需要更改规则引擎。策略管理器允许对请求处理的不同阶段进行评估和决策。策略管理器促进与规则引擎的交互，直到评估所有标准。政策经理还允许第三方开发的模块在可以决定标准的情况下提供通知，从而完成评估。
