摘要： Techniques are described for providing encryption and authentication for different types of routing protocol communications based on a variety of factors. A method comprises configuring, on a network router, a set of logical interfaces for communicating routing protocol messages with one or more peer routing devices, maintaining a set of security associations that define corresponding authentication information and encryption information for the routing protocol messages, and maintaining one or more descriptor sets that each specify a set of criteria, wherein, for at least one of the descriptor sets, the set of criteria specifies one of the logical interfaces of the network router. The method further comprises selecting one of the descriptor sets having criteria that match an individual flow, selecting one of the security associations based on the selected descriptor set, and applying the selected security association to secure the outbound flow of the routing protocol messages.

摘要： A method and system for handling otherwise rejectable messages (e.g., out-of-order messages) sent using a communication protocol (e.g., SIP) is provided. When a message is received at a protocol layer of a client system, the message (or at least its information) is passed to a higher layer (e.g., an application layer) even if it is otherwise rejectable at the protocol layer. In this way, the protocol layer provides an application layer with the option of determining whether to discard the otherwise rejectable message. In some embodiments, the protocol layer may automatically acknowledge acceptance of the message, while in other embodiments, the protocol layer may wait to receive an indication from the higher layer to determine whether to acknowledge or negatively acknowledge acceptance of the message.
摘要翻译：提供了用于处理使用通信协议（例如，SIP）发送的其他可拒绝消息（例如，无序消息）的方法和系统。当在客户端系统的协议层接收到消息时，消息（或至少其信息）被传递到较高层（例如，应用层），即使其在协议层可否拒绝。以这种方式，协议层为应用层提供了确定是否丢弃否则可拒绝消息的选项。在一些实施例中，协议层可以自动确认消息的接受，而在其他实施例中，协议层可以等待从较高层接收指示以确定是否确认或否定地确认接收消息。
