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.

Claims

1. A method for configuring a network, comprising:

grouping processing nodes of the network into a plurality of sub-networks;

organizing the sub-networks into layers where sub-networks within each layer are not directly coupled to each other; and

coupling processing nodes of a layer to at least one processing node of an above sub-network of an upper layer, unless the layer is a top layer, and at least one processing node of a below sub-network of a lower layer, or a child device.

2. The method of claim 1, further comprising coupling each processing node of each sub-network to one or more other processing nodes of the sub-network.

3. The method of claim 1, further comprising:

coupling each processing node of a sub-network to one processing node of an immediately above sub-network; and

coupling each processing node of the sub-network to at least one processing node of a below-sub-network.

4. The method of claim 1, further comprising:

coupling only one processing node of a sub-network to a processing node of an immediately above sub-network; and

coupling at least one processing node of the sub-network to one processing node of a below-sub-network.

5. The method of claim 1, further comprising:

partitioning an address space of the communication network to correspond to the layers of sub-networks; and

identifying a first portion address, a second portion address, and a third portion address of an address of the address space, wherein the first portion address corresponds to processing nodes of above sub-networks, the second portion address corresponds to processing nodes of same sub-networks, and the third portion address corresponds to below sub-networks or child devices.

6. The method of claim 1, wherein coupling the processing nodes of a layer further comprises:

coupling processing nodes of a layer to at least one processing node of a plurality of above sub-networks of an upper layer, unless the layer is a top layer.

7. The method of claim 1, wherein the network is a telecommunications network.

8. A network, comprising:

a first layer of processing nodes; and

a second layer of processing nodes, wherein;

the processing nodes of each of the first and second layers are organized into sub-networks comprised of one or more processing nodes;

sub-networks of a same layer are not directly coupled to each other; and

at least one processing node of each sub-network of the second layer is coupled to a processing node of a sub-network in the first layer, unless the second layer is a top layer, and to at least one of a processing node of a sub-network in a third layer or a child device.

9. The network of claim 8, wherein the network is a telecommunications network.

10. The network of claim 9, further comprising:

means for partitioning an address space of the telecommunication network to correspond to the layers of sub-networks; and

means for identifying a first portion address, a second portion address, and a third portion address of an address of the address space, wherein the first portion address corresponds to processing nodes of above sub-networks, the second portion address corresponds to processing nodes of same sub-networks, and the third portion address corresponds to below sub-networks or child devices.
