Distributively routed VDSL and high-speed information packets
View Patent ↗High-speed information packets are routed through a distributed communication system. Each packet destined for a subscriber unit is provided with an address indicating a destination within the communication system. In each distribution point along the path to the destination, a determination is made as to which distribution point each packet will be forwarded based on the address. Each packet is received in an access point servicing the destination, and the packet is forwarded to the destination subscriber unit.

11. The system of claim 1 wherein the network interface device is a decoder.
12. A system for distributing high-speed packetized information to a plurality of subscriber units, comprising:
a host digital terminal video distribution center for storing data and converting the data to high-speed packetized information in an optical format;
a distributed routing network comprising a plurality of distribution points, wherein a first of the plurality of distribution points is adapted to,
receive the high-speed packetized information from the host digital terminal video distribution center, the high-speed packetized information being destined for a one of the plurality of subscriber units in a coverage area serviced by a second of the plurality of the distribution points, and
forward the high-speed packetized information directly to the second of the plurality of distribution points without routing the high-speed packetized information through a central office;
an optical network unit adapted to receive the packetized information from the second of the plurality of distribution points and convert the high-speed packetized information from the optical format to a second format, wherein, the optical network unit comprises a coverage area adapted to service the one of the plurality of subscriber units; and
a network interface device adapted to receive the high-speed packetized information from the optical network unit and forward the high-speed packetized information in the second format to the one of the plurality of subscriber units.
13. The system of claim 12 , wherein the data stored on the host digital terminal video distribution center comprises a plurality of information channels adapted to be accessed by multiple subscriber units.
14. The system of claim 13 , wherein the host digital terminal video distribution center is adapted to receive a request from at least one of the plurality of subscriber units to access one of the plurality of information channels.
15. The system of claim 14 , wherein the host digital terminal video distribution center is adapted to,
respond to the request from the at least one of the plurality of subscriber units to access one of the plurality of information channels; and
deliver the one of the plurality of information channels to the one of the plurality of subscriber units.
16. A method of distributing high-speed information packets to at least one of a plurality of subscriber units, comprising:
storing data at a first distribution point comprising a host digital terminal distribution center;
converting the data into a plurality of high-speed information packets;
converting the plurality of high speed information packets into an optical format;
forwarding at least one of the plurality of high-speed information packets from the host digital terminal distribution center directly to a second distribution point through a distributed routing network without using a mobile switching center;
forwarding the at least one of the plurality of high-speed information packets from the second distribution point to an access point comprising an optical network unit;
converting the at least one of the plurality of high-speed information packets from the optical format to a second format;
forwarding the at least one of the plurality of high-speed information packets in the second format from a network interface device to the at least one of a plurality of subscriber units.
17. The method of claim 16 further comprising:
processing a request at the at least one of a plurality of subscriber units to access the data stored at the host digital terminal distribution center; and
determining if the data stored at the host digital terminal distribution center is available for distribution.
18. The method of claim 17 wherein processing a request at the at least one of a plurality of subscriber units to access the data stored at the host digital terminal distribution center comprises determining that the at least one of a plurality of subscriber units requesting the access is within the coverage area of the host digital terminal distribution center.
19. The method of claim 17 wherein processing a request at the at least one of a plurality of subscriber units to access the data stored at the host digital terminal distribution center comprises receiving a message from the at least one of a plurality of subscriber units.
