Abstract
An end user computer is assigned a multicast content distribution group by a network service intelligence platform. The network service intelligence platform authenticates a token sent by the user and signed by a third part content controller, and provides the user with credentials for joining the group. The credentials include an authorization key as well as identifications of the user and the requested content. The credentials are encrypted and authenticated by the third party content controller. The user includes the encrypted and authenticated credentials in a join request sent to a network resource, such as an edge router. After verifying the credentials, the network resource adds the end user computer to the multicast group.
