Research output: Contribution to journalArticlepeer-review


A photonic network offers a high speed circuit with WDM (wavelength division multiplexing) transmission technologies and wavelength routing technologies. In a current WDM transmission technology, the number of wavelengths which can be accommodated into one optical fiber is limited from tens to 100 wavelengths order by physical restrictions. The wavelength which is a comparatively valuable resource should be effectively used in the photonic network. To offer new network services, it is required to control optical paths dynamically. This paper describes the control technique of optical paths and newly proposed variable capacity optical path techniques both are provided by GMPLS based signaling protocols.
