Invention manages underlying application objects that support implemented business functions. A performance manager accesses and interprets application metadata and execution environment metadata, using a hierarchical entity to model complex relationships between application abstractions, components and resources. The performance manager encodes common behavioral and architecture information in models resulting from analysis of component architecture standards, vendor application servers, development tools and administration tools. The performance manager conducts inter-component dependency and control flow analysis, for example by generating control flow graphs from application metadata and performing byte code analysis without access to application source code. The performance manager collects metrics from standardized and vendor-specific sources, instruments interpreters (such as the Java Virtual Machine), and collects and utilizes resource metrics, code performance metrics, configuration parameters, and transaction, failure and lifecycle events.

Monitoring and performance management of component-based applications

Protocols and architecture for secure virtual private networks. Intraenterprise data communications are supported in a secure manner over the Internet or other public network space with the implementation of secure virtual private networks. Members of a virtual private network group exchange data that may be compressed, encrypted and authenticated, if the exchange is between members of the group.

Architecture for virtual private networks

A method of grouping content requests by one or more behaviors is provided. Each content request is labeled. Sessions for various user and service types are defined. The sessions are then modeled to create representative sessions. Each session is then matched with one or more representative sessions.

Method for grouping content requests by behaviors that relate to an information system's ability to deliver specific service quality objectives

A method is provided for defining a required information delivery system capacity as a function of a user's service quality objectives. An information delivery system behavior is modeled to understand under what conditions the user's service quality objectives are met or not met. Conditions are captured in which the user's service quality objectives are met or not met. Statistical techniques are applied to the conditions captured. A model is induced that describes the conditions in which the user's service quality objectives are met or not met.

Method of defining a required information system capacity as a function of a user's quality of service objectives

A method of determining behavior of an information system application is provided. The information system application's behavior for user content requests and load conditions is determined as is a user's quality of service objectives. The information system application's capacity allocation is then prioritized. Changes in the information system application's behavior are detected. The behavior of the information system applications is then updated in response to detecting changes that affect the user's quality of service objectives.

Method for determining behavior of an information system to control its ability to deliver a user's quality of service

A method for accepting a session in an information system server includes generating a representation of the session. The representation includes a first plurality of parameters that define a proposed additional load of the session on the information system server. A determination is made of a current state representation of the information system server. The current state representation is defined by a second plurality of parameters. The current state representation defines a current load on the information system server at a time instant. A determination is made of a headroom representation for the current state of the information system. The headroom representation is defined by a distance between a model surface.
