Abstract:
1. A node for managing admission control of multicast content on a content distribution network, the node comprising: a first interface configured to receive a multicast channel access request from at least one subscriber interface, the multicast channel access request including a multicast address for a channel stream; a memory including a subscriber profile for a subscriber associated with the at least one subscriber interface and Virtual Local Area Network (VLAN) configuration data for the content distribution network; a processor coupled to the first interface and the memory; wherein the processor identifies a first VLAN corresponding to the multicast address from the VLAN configuration data and determines whether the at least one subscriber interface is authorized to receive the channel stream via the first VLAN based on an access policy designated by the subscriber profile; wherein the processor further determines whether granting access to the channel stream violates an admission control policy based on one or both of a predefined bandwidth requirement for the first VLAN and a stream count limit for the first VLAN; wherein when the at least one subscriber interface is authorized to receive the channel stream via the first VLAN and when granting access to the channel stream does not violate the admission control policy, the processor routes the channel stream to the at least one subscriber interface.
