Traffic grooming is the term used to describe how different traffic streams are packed into
higher speed streams. In a synchronous optical network-wavelength division multiplexing …

We develop traffic grooming algorithms for unidirectional SONET/WDM ring networks. The
objective is to assign calls to wavelengths in a way that minimizes the total cost of electronic …

The SONET ring is the most widely used optical network infrastructure today. While
deploying the WDM/SONET ring, traffic grooming is an important network-design problem …

The transmission capacity of a link in today's optical networks has increased significantly
due to wavelength-division multiplexing (WDM) technology. The network performance is …

We provide network designs for optical add-drop wavelength-division-multiplexed (OADM)
rings that minimize overall network cost, rather than just the number of wavelengths needed …

Traffic grooming in wavelength division multiplexing (WDM) optical networks routes and
consolidates sub-wavelength connections onto lightpaths, to improve network utilization and …

The traffic grooming problem is of high practical importance in emerging wide-area
wavelength division multiplexing (WDM) optical networks, yet it is intractable for any but …

We consider the problem of traffic grooming in wavelength-division-multiplexing (WDM)
rings. Our objective is to minimize the required number of electronic add–drop multiplexers …

Optical networks based on wavelength-division multiplexing (WDM) tech nology offer the
promise to satisfy the bandwidth requirements of the Inter net infrastructure, and provide a …

In this paper, we investigate both static and dynamic traffic grooming problems in a
wavelength routing network, so as to minimize the total energy consumption of the core …
