Abstract:
A method of processing digital information by a point of distribution to provide dedicated bandwidth to a plurality of subscriber destinations via an Hybrid Fiber Coax (HFC) network, comprising:forwarding data packets into a plurality of data streams, each data stream corresponding to one of the plurality of subscriber destinations; framing each data packet in each data stream; segmenting encapsulated data packets into data segments; encapsulating data segments of each of the plurality of data streams into data cells to form a corresponding one of a plurality of cell streams; multiplexing the plurality of cell streams into a multiplexed cell stream, wherein said multiplexing the plurality of cell streams comprises; (a) channelizing the plurality of cell streams into cell groups, each cell group having an equal number of time slots; (b) inserting data cells from each of the plurality of cell streams into the time slots of each cell group; and modulating the multiplexed cell stream into a modulated signal within a frequency channel.
