This book is intended as a graduate/post graduate level textbook for courses on high-speed
optical networks as well as computer networks. The ten chapters cover basic principles of …

In SONET/WDM networks, a high-speed wavelength channel is usually shared by multiple
low-rate traffic demands to make efficient use of the wavelength capacity. The multiplexing is …

In SONET/WDM networks, one fiber supports multiple wavelengths and each wavelength
supports several low rate tributary streams.'Traffic grooming'then is defined as properly …

In recent years, minimization of SONET-ADMs (Synchronous Optical NETwork-Add-Drop
Multiplexers) in WDM (Wavelength Division Multiplexing) optical networks has gained a lot …

We study the benefit of reconfigurability for wavelength division multiplexed (WDM) ring
networks with dynamic single-hubbed traffic. We show that the ability to reconfigure …

A central problem in optical networks is to assign wavelengths to a given set of lightpaths, so
that at most g of them that share a physical link get the same wavelength (g is the grooming …

We consider the traffic grooming problem in WDM/SONET UPSR rings with multiple line
speeds. This is motivated by the fact that when traffic demands are non-uniform and are …

Wavelength division multiplexing (WDM) in optical fiber networks is widely viewed as the
technology with the potential to satisfy the ever-increasing bandwidth needs of network …

We consider the problem of switching cost in optical networks, where messages are sent
along lightpaths. Given lightpaths, we have to assign them colors, so that at most g …

Traffic grooming is a major issue in optical networks. It refers to grouping low rate signals
into higher speed streams, in order to reduce the equipment cost. In SONET WDM networks …
