Abstract
A network design that reduces the number of wavelengths needed to support communications in a Wavelength Division Multiplexing (WDM) network is disclosed. Wavelengths are reused in isolated sub-networks that do not share common network paths, allowing for the reduction in cost of the WDM equipment supporting the communications in the network.
Claims22
A network, comprising:
- at least four network nodes each coupled to at least three network paths, at least two of the at least three network paths coupling the at least four network nodes;
- and
- at least two sub-networks each including at least two of the at least four network nodes, the at least two sub-networks using at least one wavelength in common.
A method of supporting communications in a network, comprising:
- carrying communications on at least one given wavelength in a first sub-network of the network;
- carrying communications on the at least one given wavelength in a second sub-network of the network;
- and
- carrying communications on at least one wavelength, in addition to the at least one given wavelength, between the first sub-network and the second sub-network.
