Abstract
Wavelength assignment problem is one of the important problem in optical networks as on the first stage the route of the optical network is to be selected and after the route is selected then the wavelength is to be assigned to that route. In this paper we have proposed a wavelength assignment technique for the better performance of the optical network. The results have proved it better than the conventional algorithms.
Highlights
The rapid growth of Internet traffic has been the driving force for faster and more reliable data communication networks
In a Wavelength division multiplexing (WDM) network several optical signals are sent on the same fiber using different wavelength channels
Most important for the development of the WDM technology was the invention of Erbium Doped Fiber Amplifier, (EDFA) an optical fiber amplifier in 1987
Summary
The rapid growth of Internet traffic has been the driving force for faster and more reliable data communication networks. Apart from providing a good communication medium, cost effectiveness and sharing of available resources (programs and data) are some of the advantages of networking This rapid growth of internet traffic has been the driving force for faster and more reliable computer and data communication networks. Wavelength division multiplexing (WDM) is a very promising technology to meet the ever increasing demands of high capacity and bandwidth. The term dense wavelength division multiplexing (DWDM) is used to distinguish the technology from the broadband WDM systems where two widely separated signals (typically 1310nm and 1550nm) share a common fiber. The possibility to use the existing fibers more efficiently makes WDM a very attractive alternative commercially, as it is very expensive to install new fibers in the ground. There is wide interest towards the optical networking in academic community as it offers a rich research field for scientists from the component level up to the network protocols
