Communication network apparatus and method
First Claim
1. A method for routing communication signals in a network organized into layers of sub-networks, comprising:
- receiving in a sub-network, a communication signal from another sub-network, wherein each sub-network of each layer in the network is comprised of a processing node, and wherein the communication signal is received by the processing node in the sub-network;
selecting a carrier signal based on a destination address of the communication signal; and
outputting the carrier signal to a different sub-network via one of a plurality of ports associated with the carrier signal of the processing node that received the communication signal, wherein each one of the plurality of ports is pre-assigned to one of a plurality of different carrier signals;
extracting a first portion address from the destination address;
selecting a carrier signal corresponding to a first processing node of an above sub-network if the first portion address does not include an address of the first processing node of the above sub-network; and
outputting the carrier signal to the first processing node;
selecting a carrier signal corresponding to a second processing node of a below sub-network if the first portion address does include the address of the first processing node of the above sub-network; and
outputting the carrier signal to the second processing node.

Abstract
A communication network apparatus and method for routing communication signals from a source device to a receiving device. The apparatus performs only local processing on communication signals to thereby increase the speed of processing the signals. A plurality of the processing nodes are combined into a plurality of sub-networks that comprise the network apparatus. Each processing node of a sub-network need only process address information pertaining to the node'"'"'s current layer, one layer above it, if any, and one layer below it, if any. Additionally, each processing node has associated communication signal frequencies/wavelengths that identify the processing node as the intended recipient of the communication signal. When a communication signal having a carrier signal with a frequency/wavelength corresponding to the processing node is received, the processing node demodulates the carrier signal and forwards the communication signal data to a processing module used to process address information to determine how to route the communication signal through the network. Communication signals may be assigned “express” frequencies/wavelengths, in which case, all of the processing nodes, except the destination processing node, of the network pass the communication signal without performing processing on the communication signal.
