    摘要： Implementations are described and claimed herein for content-based routing of messages in an overlay network. According to an exemplary implementation, routing nodes receive messages and return routing policies to the sending node based at least in part on content of the message. The routing policies include instructions for redirecting similar messages to other nodes in the overlay network. The sending node determines which policies to apply to the message. The sending node may then iterate through the routing policies, modifying the address in the message according to instructions included in the routing policies so that the message is sent, e.g., directly to the intended destination. Accordingly, the sending node is able to bypass one or more intermediary nodes to reduce latency in the overlay network.

    摘要： The present invention extends to methods, systems, and computer program products for relaying messages through firewalls. A message relay negotiates first communication parameters with relay components inside a firewall and (potentially different) second communication parameters with applications outside the firewall. The message relay receives a message from an outside application in accordance with the second negotiated parameters and maps an electronic address in the received message to an inside application. The message relay transforms the message and sends the transformed message over an established connection through the firewall to a relay component in accordance with the first negotiated parameters. The relay component receives the transformed message and transforms the transformed message back into the message. The relay component delivers the message to the inside application in accordance with the second negotiated parameters.

    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 In either case, the client is notified that the cached policy is no longer valid and that a current policy should be requested.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。

    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： The present invention provide for an algebraic mapping of a policy expression from a compact to a normalized form, both in Boolean and set formulations. The policy algebra is defined in such a way that policy alternatives within the normalized expression will be the same across equivalent compact expressions—regardless of how the assertions are arbitrarily constrained or what operators are used to constrain such equivalent expressions. Moreover, the present invention also provides a model for identifying alternatives that are equivalent by comparing only the root element names or QName of each assertion within an alternative. In addition, embodiments as described herein can utilize the identification of equivalent alternatives in order to create an intersection policy expression to limit alternatives of admissible behavior to those in common across both endpoints.
