    • In general, techniques are described for simplifying admission control signaling between subscriber devices, access nodes, and service edge routers to facilitate subscriber-specific admission control for multicast streams. In one example, a service edge router receives a service request and accesses a subscriber profile to determine whether the requesting subscriber is authorized to receive the service. Upon authorization, the service edge router returns the service request to the access node in a substantially similar form in which the service request was received. The access node receives the service request on a service edge router-facing interface, indicating the service edge router has granted authorization for the subscriber device to receive multicast traffic associated with the multicast group identified within the service request. The access node therefore modifies internal mapping tables that determine local elaboration of multicast traffic associated with the multicast group to include an interface to the subscriber device.
    • 一般来说,描述了用于简化订户设备,接入节点和服务边缘路由器之间的接纳控制信令的技术,以便于组播流的用户专用接纳控制。 在一个示例中,服务边缘路由器接收服务请求并访问用户简档,以确定请求用户是否被授权接收服务。 经授权,服务边缘路由器以接收服务请求的基本相似的形式向接入节点返回服务请求。 接入节点在服务边缘面向路由器的接口上接收业务请求,指示业务边缘路由器已经授权用户设备接收与业务请求内识别的组播组相关的组播流量。 因此,接入节点修改内部映射表,其确定与组播组相关联的组播流量的本地详细描述,以包括到用户设备的接口。

    • In one example, a method includes receiving, with a network device, a portion of a subscriber session packet flow for a subscriber session, and reassembling application-layer data from data packets in the subscriber session packet flow into one or more application flows for the subscriber session. The method includes identifying, from the application flows, application identity information for the application flows, and applying a first session policy to the subscriber session. Applying the first session policy includes applying one or more application policies to the application flows in the subscriber session based on subscriber information and the application identity information for the application flows. The method includes processing the application flows in the subscriber session for accessing a packet data network in accordance with the application policies.
    • 在一个示例中,一种方法包括使用网络设备接收订户会话的用户会话分组流的一部分,以及将应用层数据从订户会话分组流中的数据分组重新组合成一个或多个应用流 用户会话。 该方法包括从应用流中识别应用流的应用标识信息,以及将第一会话策略应用于用户会话。 应用第一会话策略包括基于用户信息和应用流的应用标识信息将一个或多个应用策略应用于用户会话中的应用流。 该方法包括根据应用策略处理用户会话中的应用流,以访问分组数据网络。
