We review technologies and architectures for WDM optical IP networks from the viewpoint of
capital expenditure and network energy consumption. We show how requirements of low …

While all-optical networking had its origins in the research community a quarter of a century
ago, the realization of the vision has not had a straight trajectory. The original goal of the all …

This paper examines the role of optical and electronic technologies in future high-capacity
routers. In particular, optical and electronic technologies for use in the key router functions of …

The wavelength routed network (WRN) accommodates traffic demands by establishing
lightpaths along the corresponding routing paths. The wavelength of each lightpath is …

The transport network paradigm is moving toward next-generation networks that aim at IP
convergence, while architectures and technologies are diversifying. Video technologies …

The advent of fiber optic transmission systems and wavelength division multiplexing (WDM)
have led to a dramatic increase in the usable bandwidth of single fiber systems. This book …
