Abstract
A method includes retrieving an intermediate node policy characterizing communication properties supported by an intermediate node, the intermediate node being between a source node and a destination node in a communication path. The method includes forming a first policy-compliant message in accordance with the intermediate node policy, the first policy-compliant message including a request for a destination node policy characterizing communication properties supported by the destination node. A system includes a policy retriever comparing a source policy to one to an intermediate policy to determine whether the source policy is compatible with the intermediate policy. A message generator generates a policy request message by applying the intermediate policy to a request for a policy related to a destination node.
