Abstract
A system is provided for controlling a multicast session in a network having multiple network nodes. The system selects one of the network nodes as a control point associated with the multicast session. Identity of the control point is then advertised to all network nodes in a particular area. The control point determines multicast control information for the multicast session. Multicast control information determined by the control point is transmitted to the network nodes participating in the multicast session. The multicast control information may include network nodes participating in the multicast session, multicast reflection points, or instructions for transmitting multicast data to members of the multicast session. Updating of the multicast control information occurs in response to network changes. The system may provide a secondary control point that maintains a copy of control information associated with the multicast session.
