Establishment of an end to end virtual connection
View Patent ↗A method for establishing an end-to-end virtual circuit is provided. The method includes establishing a permanent virtual circuit between customer premises equipment and a digital subscriber line access multiplexer. The method further includes embedding information for a permanent virtual connection between a switch and a remote node in a packet transmitted over a static connection in a network. Finally, the method includes establishing a permanent virtual circuit between the switch and the remote node based on the embedded information.
1. A digital subscriber line access multiplexer, comprising:
at least one channel card coupled to at least one customer premises equipment over a communication line;
at least one line card, coupled to a data network, the line card for providing communication between the at least one customer premises equipment and a remote node coupled to the data network; and
wherein information for a permanent virtual connection between the remote node and a switch of the data network is embedded in a packet transmitted over a static connection in the data network between the at least one line card and the switch.
2. The digital subscriber line access multiplexer of claim 1 , wherein the at least one channel card comprises a channel card that supports one of asymmetric digital subscriber line (ADSL), symmetric digital subscriber line (SDSL, G.SHDL), high bit rate digital subscriber line (HDSL), very high bit rate digital subscriber line (VHDSL), and rate adaptive digital subscriber line (RDSL) service.
3. The digital subscriber line access multiplexer of claim 1 , wherein the information comprises information embedded in a destination address of the packet.
4. The method of claim 3 , wherein the information comprises port, virtual path identifier (VPI) and virtual channel identifier (VCI) for the permanent virtual circuit between the switch and the remote node embedded in the destination address of the packet transmitted over the static connection.
5. The method of claim 3 , wherein the information comprises slot, port, virtual path identifier (VPI) and virtual channel identifier (VCI) for the permanent virtual circuit connection between the switch and the remote node embedded in the destination address of the packet transmitted over the static connection.
6. A method for establishing an end-to-end virtual circuit, the method comprising:
establishing a permanent virtual circuit between a digital subscriber line modem and a digital subscriber line access multiplexer;
embedding at least slot, port, VPI and VCI information for a permanent virtual connection between a switch and a remote node in a packet;
transmitting the packet over a static connection in a data network between the digital subscriber line access multiplexer and the switch; and
establishing a permanent virtual circuit between the switch and the remote node based on the at least slot, port, VPI and VCI information to complete the end-to-end connection.
7. A communications system, comprising:
a data network;
a switch of the data network;
a digital subscriber line access multiplexer, coupled to the data network and the switch of the data network, comprising:
at least one channel card coupled to at least one customer premises equipment over a communication line;
at least one line card, coupled to a data network, the line card for providing communication between the at least one customer premises equipment and a remote node coupled to the data network; and
wherein a permanent virtual connection exists between the remote node and the switch of the data network based on information embedded in a destination address of a packet transmitted over a static connection between the switch of the data network and the digital subscriber line access multiplexer.
8. The system of claim 7 , wherein the at least one channel card comprises a channel card that supports one of asymmetric digital subscriber line (ADSL), symmetric digital subscriber line (SDSL, G.SHDL), high bit rate digital subscriber line (HDSL), very high bit rate digital subscriber line (VHDSL), and rate adaptive digital subscriber line (RDSL) service.
9. The system of claim 7 , wherein the switch of the data network and the remote node comprise a permanent virtual circuit.
10. The system of claim 9 , wherein the information embedded in the destination address of the packet comprises slot, port, virtual path identifier (VPI) and virtual channel identifier (VCI) information for the permanent virtual connection between the switch and the remote node.
