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 is 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.

1. A medium interface, comprising: a filter;three input ports directly coupled to the filter; andthree output ports directly coupled to the filter, wherein a signal is received through one of the three input ports and the filter directs the signal to one of the three output ports based on a frequency of the signal, wherein a first output port of the three output ports corresponds to a processing module for interfacing with a processing node of a sub-network in a first layer, wherein a second output port of the three output ports corresponds to an interface for interfacing with a processing node of a sub-network in a second layer that is higher than the first layer, and wherein a third output port of the three output ports corresponds to an interface for interfacing with a processing node of a sub-network in a third layer that is higher than the second layer, wherein the sub-network in the first layer, the sub-network in the second layer and the sub-network in the third layer are different sub-networks of a network. 2. The medium interface of claim 1, wherein the filter directs signals of a first frequency to the first output port, signals of a second frequency to the second output port and signals of a third frequency to the third output port. 3. The medium interface of claim 1, wherein the filter includes a digital filter. 4. The medium interface of claim 1, wherein the filter includes a band pass filter. 5. The medium interface of claim 1, wherein the filter includes a dichroic mirror. 6. The medium interface of claim 1, wherein the filter directs the signal based on whether the frequency of the signal identifies the signal to be an express signal or a non-express signal. 7. The medium interface of claim 1, wherein the filter includes an optical filter. 8. The medium interface of claim 1, wherein the filter includes a low pass filter. 9. The medium interface of claim 1, wherein the filter includes a high pass filter. 10. The medium interface of claim 1, wherein the filter includes a prism. 11. The medium interface of claim 1, wherein the filter includes an optical switch. 12. A method, comprising: receiving a signal through one of the three input ports directly connected to a filter of an interface medium; anddirecting, by the filter, the signal to one of three output ports directly coupled to the filter based on a frequency of the signal, wherein a first output port of the three output ports corresponds to a processing module for interfacing with a processing node of a sub-network in a first layer, wherein a second output port of the three output ports corresponds to an interface for interfacing with a processing node of a sub-network in a second layer that is higher than the first layer, and wherein a third output port of the three output ports corresponds to an interface for interfacing with a processing node of a sub-network in a third layer that is higher than the second layer, wherein the sub-network in the first layer, the sub-network in the second layer and the sub-network in the third layer are different sub-networks of a network. 13. The method of claim 12, wherein the filter directs signals of a first frequency to the first output port, signals of a second frequency to the second output port and signals of a third frequency to the third output port. 14. The method of claim 12, wherein the filter includes a digital filter. 15. The method of claim 12, wherein the filter includes a band pass filter. 16. The method of claim 12, wherein the filter includes a dichroic mirror. 17. The method of claim 12, wherein the filter directs the signal based on whether the frequency of the signal identifies the signal to be an express signal or a non-express signal. 18. The method of claim 12, wherein the filter includes an optical filter. 19. The method of claim 12, wherein the filter includes a low pass filter. 20. The method of claim 12, wherein the filter includes a high pass filter.
