    • An intrusion detection system for a computer network includes a knowledge database that contains a baseline of normal host behavior, and a correlation engine that monitors network activity with reference to the knowledge database. The correlation engine accumulating information about anomalous events occurring on the network and then periodically correlating the anomalous events. The correlation engine generates a worm outbreak alarm when a certain number of hosts exhibit a role-reversal behavior. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
    • 用于计算机网络的入侵检测系统包括包含正常主机行为的基准的知识数据库,以及参考知识数据库来监视网络活动的相关引擎。 相关引擎累积关于在网络上发生的异常事件的信息,然后周期性地关联异常事件。 当一定数量的主机出现角色反转行为时,相关引擎会生成蠕虫爆发警报。 要强调的是,该摘要被提供以符合要求抽象的规则,允许搜索者或其他读者快速确定技术公开内容的主题。 提交它的理解是,它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72(b)。

    • Methods and apparatuses for identifying and alleviating bottlenecks prior to processing packets in internal feature modules are described. First, a method is provided for aggregating the service policies of various physical interfaces, and using results of the aggregation to determine whether a packet processing engine is capable of satisfying the aggregated service policy information. Second, a method and apparatus for applying the aggregated service policy prior to processing in an internal feature module, such as a crypto-engine. Packets on routers/switches are expected to be subjected to certain policies to address resource contention or streamlining/prioritization on outbound interfaces. Internal bottlenecks that a user can neither see nor control may cause packet transmission guarantees to be violated. Encryption is an example of an internal service that adds overhead thereby creating an internal bottleneck. Such internal bottlenecks are cured through intelligent means of pre-processing and pre-application of certain policy rules.
    • 描述在内部特征模块中处理分组之前识别和减轻瓶颈的方法和装置。 首先,提供一种用于聚合各种物理接口的业务策略的方法,并且使用聚合结果来确定分组处理引擎是否能够满足聚合的服务策略信息。 其次,在诸如密码引擎的内部特征模块中处理之前应用聚合服务策略的方法和装置。 路由器/交换机上的数据包预计将受到某些策略的限制,以解决出站接口的资源争用或简化/优先级排序。 用户既不能看到也不能控制的内部瓶颈可能会导致数据包传输保证被违反。 加密是内部服务的一个例子,它会增加开销,从而创建内部瓶颈。 这种内部瓶颈是通过预处理和预先应用某些策略规则的智能手段来治愈的。
