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.

Pass-through multicast admission control signaling

A network device establishes a logical channel with each server device of multiple server devices, where each logical channel is not shared with another server device of the multiple server devices. The network device also determines a network loopback Internet protocol (IP) address for each server device of the multiple server devices, and associates each network loopback IP address with a corresponding logical channel. The network device further receives a packet destined for a particular server device, and provides the packet to the particular server device via the logical channel associated with the particular server device.

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.
