Abstract:
1. A method comprising: receiving, by a computing device from one or more devices in communication with the computing device via an access network, one or more request communications requesting access to a multicast group; identifying, by the computing device, a bandwidth requirement for the multicast group from a content distribution map that specifies information for one or more permitted multicast groups to which the one or more devices are permitted access; using the bandwidth requirement and information describing current data traffic levels for the access network to determine that there is sufficient bandwidth on the access network to begin transmitting data of the multicast group to the one or more devices; and conditioned upon determining that there is sufficient bandwidth on the access network to begin transmitting data of the multicast group to the one or more devices, transmitting, by the computing device, one or more communications requesting membership in the multicast group.
