Method and system for managing access to multicast groups
First Claim
1. A method of configuring a plurality of nodes to receive multicast content from a plurality of multicast addresses, such that each node is capable of relaying multicast content, said method comprising:
- identifying a group of nodes to be configured;
storing a list of multicast group addresses to be made available to each node in the group of nodes;
distributing all of the multicast group addresses from the list to each node in the group of nodes; and
enabling each node to receive multicast content from each of the multicast group addresses in the list distributed to each node in the group of nodes.

Abstract
A method and system for managing the distribution of multicast content are provided. The method involves creating a list of multicast group addresses to be made available to user units supported by a group of nodes. The list is distributed to all of the nodes in the group of nodes. Filters are created to limit the multicast content that each user unit can receive. The filters are created by referencing the list of multicast addresses previously created. The filters are distributed to the appropriate nodes and applied on customer ports.

6. A method of configuring a plurality of nodes to receive multicast content from one or more multicast addresses, such that each node is capable of relaying multicast content, the method comprising:
-
recording on a machine readable medium a list of data representing each multicast address to be transmitted to a node, supplying stored data from the list to communication signal generation and transmission means, transmitting from the communication signal generation and transmission means data based on the supplied data to a plurality of said nodes, and enabling said plurality of nodes to receive multicast content from each multicast address, whose representative data is transmitted from said communication signal generation and transmission means to said plurality of nodes. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method of creating a filter for limiting data transmission from a port of a node to a user unit connected to the port, the method comprising identifying a set of data representing one or more multicast address, said set of data being stored in data storage means, and electronically importing said data from said data storage means into said filter.

15. A system for configuring a plurality of nodes to receive multicast content from a plurality of multicast addresses such that each node is capable of relaying multicast content to one or more user units, the system comprising:
storage means storing a list of nodes in a predetermined group of nodes and storing a predefined list of multicast group addresses to be made available to each node in the predetermined group, and signal generation means for generating one or more communication signal, each containing one or more multicast group address from the list, the communication signal addressed to each node in the predetermined group such that all multicast addresses in the list are transmitted to each node in the group. - View Dependent Claims (16, 17, 18, 19, 20)
