Method and apparatus for determining an enforceable policy applicable to one or more network devices. The method includes attaching one or more rule elements to one or more domain elements to create policies, the domain elements representing network devices and groups of network devices, and the rule elements defining actions, a method for determining whether a conflict exists between the polices, and a method for resolving the conflicts to produce one or more enforceable policies.

Policy management and conflict resolution in computer networks

Apparatus and method for monitoring parameters that govern the operational characteristics of a network device, including the use of templates for generating configuration records of network devices of a selected model type. A database of models is provided, each model representing an associated network device and including attribute values for the parameters of the associated network device. Templates are used to screen a model in order to retrieve values for each of the attributes and create a configuration record. The configuration records may be stored in the configuration manager or other storage device, and/or transferred to the pre-existing model database for use by a network management system in reconfiguring the associated network devices. Additionally, a method and apparatus is provided that defines network groups, defines network policies for groups, determines conflicts, and resolves conflicts among groups and devices. This system for configuration management is less time consuming, expensive, and error prone than prior systems.

Method and apparatus for providing a call-tapping point in a switched network with point-to-multipoint functionality. The tapping point is added as an additional destination for data being sent from a source node to a first destination node. The tapping point is also added as a destination for data being sent from the first destination node to the source node. A merge operation is performed for finding and combining common segments of the paths between the source and destination, the source and tapping point, and the destination and tapping point.
