    摘要： 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.

    摘要： Implementations are described and claimed herein to detect an invalid policy that may reside in a cache at a client. An expired policy is removed from cache and a current policy is requested. Otherwise the cached policy may be used. The client indicates which policy it is using by generating a policy digest, including, in compressed form, one or more assertions. If the host determines the policy digest is invalid, the host issues an invalid digest fault. If the policy digest is valid, but the assertions included in the policy digest are invalid, the host issues an invalid policy fault. In either case, the client is notified that the cached policy is no longer valid and that a current policy should be requested.

    摘要翻译： 这里描述和要求的实现来检测可能驻留在客户端的高速缓存中的无效策略。 从缓存中删除过期的策略，并请求当前策略。 否则可能会使用缓存的策略。 客户端通过生成策略摘要来指示其使用哪个策略，包括压缩形式的一个或多个断言。 如果主机确定策略摘要无效，则主机发出无效的摘要故障。 如果策略摘要有效，但策略摘要中包含的断言无效，则主机发出无效的策略故障。 在任一情况下，通知客户端缓存的策略不再有效，并且应该请求当前的策略。
