Multicasting in WDM networks [PDF]

open access: yesIEEE Communications Surveys and Tutorials, 2002
Wavelength-division multiplexing (WDM) networks are believed to be a promising candidate to meet the explosive increase of bandwidth demand in the Internet. In this article, we survey the problems of and approaches to multicasting in WDM networks. In particular, we address the issues in the context of three types of WDM networks: broadcast-and-select ...

Performance of WDM transport networks [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 1998
Wavelength division multiplexed point-to-point transport is becoming commonplace in wide area networks. With the expectation that the next step is end-to-end networking of wavelengths (in the optical domain without conversion to electronics), there is a need for new design techniques, a new understanding of the performance issues, and a new performance
