    • A method, system, apparatus, and computer program product are presented for a dynamically locatable packet analyzer spread across a distributed network of endpoints for determining packet generating applications is provided. In particular, the analyzer determines which ports are being used by which applications in order to verify that only intended packets are being sent and received by endpoints. The analyzer also provides novice packet snooping by not requiring administrators to configure operating system specific, packet specific or port specific information. The analyzer also provides snooping per application type (i.e. security, discovery, etc.) on endpoints, rather than packet type or port only.
    • 提供了一种方法,系统,装置和计算机程序产品,用于分布在分布式端点网络上的动态可定位分组分析器,用于确定分组生成应用。 特别地,分析器确定哪些端口正被哪些应用程序使用,以便验证端点只发送和接收预期的分组。 该分析器还提供新手的数据包窥探,不需要管理员配置特定于操作系统,特定于数据包或端口的信息。 分析器还在端点上提供每种应用类型的窥探(即安全性,发现等),而不仅仅是分组类型或端口。

    • A method, system, apparatus, and computer program product is presented for management of a distributed data processing system. The network management framework is able to monitor multiple sources of network packets on various subnets within the distributed data processing system; distributed packet snoopers are deployed from a packet usage manager to monitor the multiple sources of network packets. The system administrator can request packet filtering based upon selected active users or active applications. A bandwidth history database is compiled from bandwidth usage data associated with multiple entities within the data processing system, including users, applications, and/or endpoints within the data processing system. In response to a requested action within the data processing system, bandwidth usage for the requested action can be predicted with reference to the bandwidth history database. The actual and predicted bandwidth usage of requested actions can be displayed to the system administrator in real time.
    • 提出了一种用于管理分布式数据处理系统的方法,系统,装置和计算机程序产品。 网络管理框架能够在分布式数据处理系统内的各个子网上监控网络数据包的多个来源; 从分组使用管理器部署分布式分组侦听器来监视多个网络分组源。 系统管理员可以根据选定的活动用户或活动应用程序请求包过滤。 带宽历史数据库是从与数据处理系统内的多个实体(包括数据处理系统中的用户,应用程序和/或端点)相关联的带宽使用数据进行编译的。 响应于数据处理系统内的所请求的动作,可以参考带宽历史数据库来预测所请求动作的带宽使用情况。 请求操作的实际和预计带宽使用量可以实时显示给系统管理员。

    • A method, system, apparatus, and computer program product are presented for a distributed port firewall system. The distributed port firewall system provides mapping of port usage to application needs, application action object (AAO) used to identify the use of ports. Application action object may be opened based on endpoint and user. Port firewall “properties” are added in order to configure firewall which are only configurable by certain trusted users or applications. Different policies applied to usage and the opening of ports based on both a collection of endpoints, managed regions, or on a per endpoint basis. Beyond just allowing an application to open a port, the allowed packet types are also configured to work in conjunction with a distributed packet snooper session.
    • 为分布式端口防火墙系统提供了一种方法,系统,设备和计算机程序产品。 分布式端口防火墙系统提供端口使用情况对应用需求的映射,用于识别端口使用的应用程序动作对象(AAO)。 应用程序操作对象可以基于端点和用户打开。 添加端口防火墙“属性”,以配置只能由某些受信任的用户或应用程序配置的防火墙。 基于端点,管理区域或每个端点的集合,不同的策略适用于端口的使用和打开。 除了允许应用程序打开端口之外,允许的数据包类型还配置为与分布式数据包窥探会话一起工作。

    • A system and method for programming applications to respond to slow links. The programming may be done during configuration of a system, or it may be implemented dynamically in response to a recently-detected change in network performance. The method includes the steps of continually monitoring links in a network, periodically calculating runtime link speeds for the links, and identifying slow links based on the monitoring and calculating. The method may additionally include the preliminary step of predefining so-called original link speed factors for the links. Runtime determination of runtime link speed factors for the respective links and comparison of the original link speed factors to the real-time link speed factors will then be used for the identification of slow links. A variety of application responses may be programmed as slow link responses.
