Abstract
The high data transmission capacity of fiber optic networks has been exploited through wavelength division multiplexing (WDM). By using multiple independent wavelengths, or lambdas, the fiber can carry a multiplicity of content, each in its own lambda. As the number of lambdas increases (it is currently ca. 100 and is projected to climb to 100,000 or more) it becomes increasingly challenging to allocate lambdas to traffic. The present invention automates the allocation process by detecting similar interests amongst groups of users, and creating a shared lambda for use by the users.
