    • Methods and apparatus for efficient routing in communication networks. In an aspect, a method is provided for traffic routing between first and second nodes in a communication network. The method includes detecting traffic transmitted between the first and second nodes, transmitting a request to a mobility agent associated with the first node to request authorization for a route optimization between the first and second nodes, receiving a response that authorizes the route optimization, and establishing an optimized route. In an aspect, an apparatus includes detector logic for detecting traffic transmitted between the first and second nodes, transmitting logic for transmitting a request to a mobility agent associated with the first node to request authorization for a route optimization between the first and second nodes, receiving logic for receiving a response that authorizes the route optimization, and connection logic for establishing an optimized route.
    • 通信网络中有效路由的方法和装置。 在一方面,提供了一种用于通信网络中的第一和第二节点之间的业务路由的方法。 该方法包括检测在第一和第二节点之间传输的业务,向与第一节点相关联的移动性代理发送请求以请求对第一和第二节点之间的路由优化的授权,接收授权路由优化的响应,以及建立 优化的路线。 一方面,一种装置包括用于检测在第一和第二节点之间传输的业务的检测器逻辑,用于向与第一节点相关联的移动性代理发送请求的请求的逻辑,以请求第一和第二节点之间的路由优化的授权,接收 用于接收授权路由优化的响应的逻辑,以及用于建立优化路由的连接逻辑。

    • In a communication session in which data flows with encrypted data packets pass through a monitoring intermediary for data traffic control. The encrypted data packets include SPIs (Secured Parameter Indexes) which are used to identify SAs (Security Associations) for data decryption. During the initial signaling process for the communication session, the nodes seeking the communication session include the SPIs in the signaling messages and send the signaling messages through the monitoring intermediary which in turn matches the SPIs of the signaling messages with the corresponding SPIs extracted from the data packets. In enforcing data traffic control, the monitoring intermediary allows data flows to pass through if comparison matches in the SPIs are found. Otherwise, the data flows are rejected.
    • 在具有加密数据分组的数据流通过用于数据业务控制的监视中介的通信会话中。 加密的数据包包括用于识别用于数据解密的SA(安全关联)的SPI(安全参数索引)。 在通信会话的初始信令过程期间,寻求通信会话的节点包括信令消息中的SPI,并通过监控中介发送信令消息,监控中介又将信令消息的SPI与从数据中提取的对应的SPI进行匹配 数据包 在执行数据流量控制时,监控中介允许数据流通过,如果发现SPI中的比较匹配。 否则,数据流将被拒绝。
