  • Policy change characterization method and apparatus
    Patent number: 6980555
    Abstract: A method and apparatus is described for receiving a new policy tree at a network element in a network. The network element stores a current policy tree of classes for quality of service of packets being processed by the network element. Classes of the current policy tree are compared with the classes of the new policy tree. Classes of the current policy tree are selectively deleted and classes of the new policy tree are selectively added to the current policy tree based on the comparison of the classes.

  • Methods and apparatus for deploying quality of service policies on a data communication network
    Patent number: 6449650
    Abstract: A network policy management system and methods define service templates. The service templates contain information on the topologies of services such as video calls, web services, order processing applications, or the like. The service templates also contain information about the quality of service required by each of the data flows which will be generated when an instance of the service is used. The policy management system allows users to add new services by selecting a service template and specifying endpoints for the service on a map of the network. The system automatically generates updated packet forwarding rules for use at a plurality of packet processing devices in the network.
