ATM multicasting for delivering information over a network
First Claim
1. A method for multicast delivery of information in a DSL network comprising the steps of:
- receiving requests for multicast information from multiple destination ports;
transmitting, from a network control system, separate, respective requests to a switch and a multiplexer to join or build a multicast point to multipoint connection for a given subscriber;
creating transmission paths between a single source port and multiple destination ports on said DSL network in response to said requests;
receiving the multicast information at said source port;
determining which of said destination ports is to receive said multicast information; and
distributing said information from said source port to selective ones of said destination ports based on said step of determining.

Abstract
A method that provides for multicast delivery of information in a DSL network includes creating transmission paths between a single source port and multiple destination ports in a DSL network; receiving information at the source port; determining which of the destination ports is to receive the information; and distributing the information from the source port to selective ones of the destination ports based on the prior referencing step. A DSL system for providing multicast delivery of information includes an ATM network layer for sending information, a digital subscriber line access multiplexer (DSLAM) coupled to the ATM network layer for receiving the information, and a network control system for controlling selective multiplexing of the information through the digital subscriber line access multiplexer (DSLAM).

-
receiving requests for multicast information from multiple destination ports; transmitting, from a network control system, separate, respective requests to a switch and a multiplexer to join or build a multicast point to multipoint connection for a given subscriber; creating transmission paths between a single source port and multiple destination ports on said DSL network in response to said requests; receiving the multicast information at said source port; determining which of said destination ports is to receive said multicast information; and distributing said information from said source port to selective ones of said destination ports based on said step of determining. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A DSL system for providing multicast delivery of information comprising:
-
an ATM network for sending information, and configured to receive multiple requests for multicast information; a switch that is on the ATM network; a digital subscriber line access multiplexer (DSLAM) coupled to said ATM network for receiving said multicast information; and a network control system for controlling selective multiplexing of said multicast information through said switch and said DSLAM in response to said requests for said multicast information, wherein the network control system is also for transmitting separate, respective requests to the switch and the DSLAM to join or build a multicast point to multipoint connection for a given subscriber. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for multicast delivery of information in a DSL network comprising the steps of:
-
receiving requests for multicast information from multiple destination ports; transmitting, from a centralized network control system, separate, respective requests to a switch and a multiplexer to join or build a multicast point to multipoint connection for a given subscriber; creating transmission paths between a single source port and multiple destination ports on said DSL network in response to said received requests; receiving the multicast information through a multicast channel at said source port; referencing a connection profile specifying destination points of subscribers and relating the subscribers to the multicast channel within the centralized network control system, which provides address translation for the DSL network; determining which of said destination ports is to receive said multicast information based on said step of referencing; and distributing said information from said source port to selective ones of said destination ports based on said step of determining.
