Activity data is analyzed or evaluated to detect behavioral patterns and anomalies When a particular pattern or anomaly is detected, a system may send a notification or perform a particular task This activity data may be collected in an information management system, which may be policy based Notification may be by way e-mail, report, pop-up message, or system message Some tasks to perform upon detection may include implementing a policy in the information management system, disallowing a user from connecting to the system, and restricting a user from being allowed to perform certain actions To detect a pattern, activity data may be compared to a previously defined or generated activity profile

Detecting behavioral patterns and anomalies using activity profiles

The present invention discloses a method, apparatus and program storage device for providing non-blocking, minimum threaded two-way messaging. A Performance Monitor Daemon provides one non-blocked thread pair per processor to support a large number of connections. The thread pair includes an outbound thread for outbound communication and an inbound thread for inbound communication. The outbound thread and the inbound thread operate asynchronously.

Method for improving performance in a computer storage system by regulating resource requests from clients

A method for providing network access to a shared access communications medium for a plurality of users includes the steps of conducting predictive admission control by arbitrating user requests for access to the shared medium based on predicted aggregate demands, conducting lookahead scheduling for use in making user channel assignments by forecasting schedule transmission opportunities one or more channels of the shared medium, and balancing load by making channel assignments such that a plurality users are each assigned a respective channel of the shared medium based upon a predicted need. Congestion parameters can predicted for each channel of the shared medium and mapped to a congestion measure using a mathematical function that takes into account packet loss rate, packet delay, packet delay jitter, and available capacity.

Apparatus and Methods for Incorporating Bandwidth Forecasting and Dynamic Bandwidth Allocation into a Broadband Communication System

A web site provides services to uses over the Internet. End-user service-level objectives (SLOs) such as availability and performance are measured and reported to a SLO agent. User requests pass through several tiers at the web site, such as a firewall tier, a web-server tier, an application-server tier, and a database-server tier. Each tier has several redundant service components that can process requests for that tier. Local agents, operating with any local resource managers, monitor running service components and report to a service agent. Node monitors also monitor network-node status and report to the service agent. When a node or service component fails, the service agent attempts to restart it using the local agent, or replicates the service component to other nodes. When the SLO agent determines that a SLO is not being met, it instructs the service agent to replicate more of the constraining service components or increase resources.

Monitoring and control engine for multi-tiered service-level management of distributed web-application servers

Method and apparatus for service level management, wherein business processes are composed of services. A state of the service is defined by one or more service parameters, and the service parameters depend upon performance of network components that support the service, e.g., component parameters. The state of the service may depend, for example, on a collection of service parameter values for availability, reliability, security, integrity and response time. A service level agreement is a contract between a supplier and a customer that identifies services supported by a network, service parameters for the services, and service levels (e.g., acceptable levels) for each service parameter.

Service level management

A method and apparatus are provided for evaluating Service Level Agreements (SLAs) that describe the level of services that are to be provided to customers by Internet Service Providers (ISPs) or Enterprise Service Providers (ESPs). The method and apparatus are utilized to measure the quality of service being provided to customers and to determine whether or not the quality of service is in compliance with an SLA that characterizes the level of service to be provided to customers. Such services include, for example, electronic mail (e-mail), Voice-Over-IP (Voice Over Internet protocol), networking services and web hosting.

Method and apparatus for processing quality of service measurement data to assess a degree of compliance of internet services with service level agreements

A system for rapid testing of devices includes a test performance component capable of testing an intermittently operated device, an interface component capable of providing a release interval value and a measurement interval value, and a test control component capable of receiving the release interval value and the measurement interval value from the interface component and of providing the release interval value and the test interval value to the test performance component, and the test performance component being capable of initiating interaction between the intermittently operated device and the test performance component, of performing a plurality of tests, each test from the plurality of tests occurring over one test interval value, and of terminating the plurality of tests after a predetermined condition is satisfied.

System and method for rapid testing of intermittently operated devices

The system and method of the present invention combine multiple tests ( 15 ) into a batch and submit the batch for processing to exercise electronic circuits, for example, a managed network ( 25 ) such as a wireless network. The system and method insure that tests ( 15 ) are timely run by utilization of a batch submit trigger ( 42 ). When a test ( 15 ) has completed, the system and method return the results ( 11 ) of that particular test ( 15 ) to the user, regardless of whether or not the rest of the tests ( 15 ) in the batch have completed execution.

System and method for testing of electronic circuits

A system and method to provide simulations of tests that execute in a communications network environment. The system and method include a test object and a simulator framework, coupled with an agent manager. The test object can initiate either live or simulated testing, or both. Live test characteristics, that result from the execution of the live test, can be used to create a test characteristics for the same test that is simulated by the simulator framework. The agent manager, coupled directly and/or through storage media to the simulator framework and the test object, can provide the results of live or simulated testing.

System and method for test simulation

A system and method to enable balanced resource utilization during testing of a wireless communications network. The system and method determines the properties, including the status, for resources, and stores the properties for later comparison. Utilization information is calculated from the properties and provided to the user based on criteria from user-specified resource filters. Balanced resource utilization is enabled based on the utilization information.
