A network testing environment includes a control server and a testing cluster composed of one or more load generating devices. The load generating devices output network communications in a non-deterministic manner to model real-world network users and test a network system. The load generating devices operate in accordance with probabilistic state machines distributed by the control server. The probabilistic state machines model patterns of interaction between users and the network system.

A service deployment device responds to events originating internally or in a network using a set of condition/action rules. The condition/action rules are defined in terms of business-level information. A rules engine in the service deployment device translates the network events to business information and uses a forward-chaining algorithm to evaluate conditions associated with the rules. Based on the evaluation, the service deployment device enables actions associated with the rules. An enterprise using the service deployment device uses the condition/action rules to deploy business policies in the network.
摘要:
A network management system is described for assuring that a network device complies with a device-specific configuration policy. One example of the network management system contains one or more business rules that describe a business policy regarding a computer network in a network-independent form. In general, the business rules refer to high-level business requirements and not to device-specific configuration information. The network management system uses the business rule to determine which business policies are currently in force. In addition, the network management system contains one or more network design rules that describe relationship between the business policy and one or more device-specific configuration policies. The network management server uses the network design rules to determine whether to deploy a device-specific configuration policies. In this manner, an administrator or other user may create high-level business rules without regard to particular network devices or topologies, yet device-specific configuration polices are deployed to the network devices to assure compliance even if the network management system is bypassed.

摘要:
A service provider network includes an automated support module that receives stream of network packets from subscribers and separates this streams into packet flows for analysis. The automated support module may be an intermediate device that examines each packet flow to detect subscriber characteristics for each subscriber. The automated support module may apply a set of analysis rules to the detected characteristics to aid diagnosis of reported or potential network errors.
