A method and system for authenticated access to multicast traffic receives a request for a user to join a multicast channel. Access privileges of the user to the multicast channel are authenticated. The request is disallowed in response to at least an unsuccessful authentication.

Method and system for authenticated access to internet protocol (IP) multicast traffic

A method for handling access requests at multiple PoPs using the sharing of NAS information between the PoPs, enabling each PoP to maintain its own, independent, database of user records. When an access request is received, it is forwarded to a specific PoP designated as the user's 'home PoP'. This home PoP is the only PoP to contain the user's records. The home PoP may then handle the access request by utilizing a local NAS list, the local NAS list being synchronized with other NAS lists in the network and providing information on all the 'known' NASes throughout the entire network. This allows for a user to roam between PoPs, while reducing the bandwidth and security concerns that have existed in the past when users chose to roam. The NAS lists may then be updated via a central Network Control Console.

Sharing of NAS information between PoPs

A system for managing access to IP multicast traffic includes a join request manager within an access router. The access router includes a central processing unit (CPU) and a memory unit. The access router replicates multicast traffic flows for communication to one or more user devices within user systems coupled to the access router using a link. The join request manager receives a request to receive a multicast traffic flow, the request being received from one of the user devices within one of the user systems, and denies the request if a system metric is above a threshold.
