Abstract

A method for networked communications includes determining a group identifier associated with a received request for multicast data, determining an available upstream bandwidth and an available downstream bandwidth, adding an entry for the identified group into a multicast forwarding table, allocating bandwidth from the available upstream bandwidth and available downstream bandwidth, the allocated bandwidth corresponding to bandwidth required by the requested multicast data, and forwarding the received request to an upstream network destination. The method includes, if no response is received in response to the received request within a designated timeout period, removing the entry for the identified group in the multicast forwarding table, and restoring the allocated bandwidth to the available upstream bandwidth and available downstream bandwidth.
