    Abstract: Network devices, such as a router and a downstream multicast distribution device, may use multiple control channels when setting up a multicast stream for a multicast request. For example, first messages may be transmitted using a first protocol to an upstream device over a first channel, the first messages indicating when a first multicast media stream is being requested by at least one of a number of client devices. Second messages may be transmitted using a second protocol over a second channel, the second messages being transmitted on a per-client basis and each identifying a one of the client devices as requesting the first multicast media stream. By using two control channels to convey the multicast channel requests, the router may obtain visibility into the action of the subscriber and can consequently perform per-subscriber operations such as access-control, bandwidth based admission control, statistics, and QoS adjustment for multicast IPTV streams received by the subscriber.

    Abstract: A stateful application gateway redundancy system and method. Configuration information defines a service processing unit on a service gateway and associates a first redundancy set and a second redundancy set with the service processing unit, wherein the first and the second redundancy sets include a master redundancy state, a standby redundancy state and one or more redundancy policies, including at least one redundancy policy defining actions to be taken on occurrence of a redundancy event associated with the respective redundancy set. In response to detecting a critical event for the first redundancy set, the service gateway transitions the first redundancy set from the standby redundancy state to the master redundancy state, adds a first signal-route associated with the first redundancy set to a Routing Information Base (RIB) and advertises the first signal-route to routing protocol peer network devices.

    Abstract: In one example, a network device includes computer-readable storage media configured to store information defining a default dictionary associated with one or more default services provided by the network service, one or more interfaces configured to receive configuration data defining a customer dictionary associated with one or more additional services beyond the one or more default services and a to receive a request to access one of the additional services from a subscriber device, and a control unit configured to determine whether an authentication, authorization, and accounting (AAA) server grants access to the requested one of the additional services to the subscriber device, and to configure forwarding information of the network device to cause network traffic associated with the subscriber device to be forwarded to a service unit to perform the one of the additional services when the AAA server grants access to the subscriber device based on the determination.
