摘要:
A network analyzer reads network packets and extracts characterizing attributes, grouping patents observed in a given amount of time on common attribute values. Grouped attributes are meta data, written to a database, while packets are written to files.
摘要:
A method and apparatus for dynamic host operating system firewall configuration provides plural monitoring processes to monitor the firewall configuration of a host operating system and guest operating systems. When any firewall configuration change is detected by a monitor in a monitored guest operating system, an appropriate corresponding firewall change is made by the monitor to the host operating system.
摘要:
A network analyzer reads network packets and extracts characterizing attributes, grouping patents observed in a given amount of time on common attribute values. Grouped attributes are meta data, written to a database, while packets are written to files. Meta data is stored in the database including links to the physical packets related to the meta data, and a user interface enables query of the meta data and retrieval of related physical packets.
摘要:
Network monitoring method and apparatus determines the zero window event data transfer delay, reporting the amount of data transfer delay caused thereby. Non-data-transfer-delaying zero window events can be separated from those causing actual delay, allowing reporting of actual delay events separate from non-delay causing events.

摘要:
Data storage rates are dynamically adjusted in an APM system, by monitoring data storage elements and modulating the data storage when a determination is made that the storage buffer utilization is too high.
摘要:
Data acquisition rates are dynamically adjusted in an APM system, by monitoring data acquisition hardware and reducing the data acquisition rate when a determination is made that the data rate is too high for processing by an APM.
摘要:
Network traffic is distinguished at a conversation level, providing sampling decision capability. A hash value is determined based on IP addresses and protocol type, giving unique identifiers for individual conversations.
摘要:
A method and apparatus to estimate application and network performance metrics and distribute those metrics across the appropriate applications, sites, servers, and the like, performs shallow analysis on a majority of traffic and deep analysis on a sampled set of the traffic, and estimates network and application performance metrics for the non-deep analysis data, providing an overall estimate of metrics without requiring deep analysis of all traffic.

Non-data-transfer-delaying zero window events can be separated from those causing actual delay, allowing reporting of actual delay events separate from non-delay causing events.
