Wavelength division multiplexing (WDM) is the next step towards leveraging the capabilities of the optical fiber, especially for wide-area backbone optical data communication networks. In this paper, we analyze some of the key architecture and discuss the models corresponding approaches and advances made toward addressing these issues. We first analyze the different IP/WDM networking framework models, and secondly discuss the IP over switched WDM architecture. The ability to switch a signal at intermediate nodes in a WDM network based on their wavelengths is known as wavelength-routing. One of the greatest advantages of using wavelength-routing WDM is the ability to create a virtual topology different from the physical topology of the underlying network.
