Abstract
Wavelength assignment is an integral part of the network planning process in optical-bypass-enabled networks. Its need arises from the wavelength continuity property of optical bypass technology, where a connection that traverses a node all-optically must enter and exit the node on the same optical frequency. Thus, the wavelengths that are in use on one link may have ramifications for the wavelengths that can be assigned on other links. Effective wavelength assignment strategies, as covered in this chapter, must be utilized to ensure that wavelength contention is minimized. Wavelength assignment can be performed in concert with the routing process or it can be handled as a separate step; both approaches are discussed. Furthermore, as the underlying network technology grows more complex, more physical-layer impairments may need to be considered in the wavelength assignment process. Topics such as mixed line-rate networks, alien wavelengths, and maximizing the optical reach across the wavelength spectrum are addressed.
