Abstract:
A method of extending network capabilities for a network with a policy-based network management (PBNM) architecture comprising:sending a first message from a policy enforcement point (PEP) to a policy decision point (PDP) requesting configuration of conditions for a policy used to detect and manipulate distributed network state information; sending a first Java object in a second message from the PDP to the PEP in response to receiving the first message; executing the first Java object on the PEP to configure conditions for policy evaluation; sending a third message from the PEP to the PDP in response to an external event triggering run-time evaluation of policy conditions by the PEP; sending a second Java object in a fourth message from the PDP to the PEP in response to receiving the third message; and executing the second Java object on the PEP, wherein the second Java object, when executing, at least one of examines a state of another device in the network as part of evaluating a policy condition and changes the state of another device in the network.
