Abstract:
1. A method of transporting data from a source network to a destination network through an optical network over four diverse pathways comprising: assigning four wavelength channels to transport the same data; broadcasting the same data on each of the four wavelength channels simultaneously; routing two of the four wavelength channels through a first main span of the optical network and the remaining two wavelength channels through a second main span of the optical network; interrupting the first main span with one or more intermediate box and interrupting the second main span with a number of intermediate boxes corresponding to the number of first main span intermediate boxes forming corresponding pairs of intermediate boxes between the first and second main spans; connecting corresponding pairs of intermediate boxes with a transverse link; exchanging one of the two wavelength channels in the first main span with one of the two wavelength channels in the second main span through each transverse link progressing towards the destination network; receiving the four wavelength channels at the destination network; analyzing the data received in each of the four wavelength channels; detecting information of known data patterns and events; correlating the known data patterns and events using a correlation model, wherein the data pattern and event information comprises type of data, priority, size, origin, transmission delay, transmission wavelength and optical signal-to-noise ratio (OSNR); identifying patterns based on the correlation model; selecting one of the four wavelength channels as a primary wavelength channel; predicting the type, length, or priority of the data to be received in a next data broadcast based on the identified patterns; and based upon the prediction, dropping one, two or three of the four wavelength channels beginning with the wavelength channel having the most latency.
