- Title
Wavelength Translation in WDM Networks: Optimization Models and Solution Procedures.
- Authors
Kennington, Jeffery L.; Olinick, Eli V.
- Abstract
The latest technology being developed for high-speed telecommunications networks uses wavelength-division multiplexing (WDM) and optical switching. In these networks, a lightpath is a sequence of links from an origin to a destination along with the hardware needed to support traffic along this path. The capacity of a link in a WDM network corresponds to the number of wavelengths of light (called λ) that the fiber-terminating and node equipment comprising the link can support. A pair of lightpaths that share a common link must use different λ on that link, but translators can be installed at nodes to switch λ along a lightpath. Hence, a lightpath having translators at every node could use different λ on each link.
