Flexgrid technology is now considered to be a promising solution for future high-speed
network design. In this context, we need a tutorial that covers the key aspects of elastic …

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 …

In wavelength-division multiplexing (WDM) optical networks, the bandwidth request of a
traffic stream can be much lower than the capacity of a lightpath. Efficiently grooming low …

Traffic grooming refers to techniques used to combine low-speed traffic streams onto high-
speed wavelengths in order to minimize the networkwide cost in terms of line terminating …

As the operation of our fiber-optic backbone networks migrates from interconnected SONET
rings to arbitrary mesh topology, traffic grooming on wavelength-division multiplexing (WDM) …

The rapid growth in communications and internet has changed our way of life, and our
requirement for communication bandwidth. Optical networks can enable us to meet the …

In this paper, we consider the traffic grooming, routing, and wavelength assignment (GRWA)
problem for optical mesh networks. In most previous studies on optical mesh networks, traffic …

We investigate the survivable traffic-grooming problem for optical mesh networks employing
wavelength-division multiplexing (WDM). In the dynamic provisioning context, a typical …

The essential guide to the state of the art in WDM and its vast networking potential As a
result of its huge transmission capacity and countless other advantages, fiber optics has …

We employ a new, generic graph model for dynamic traffic grooming in WDM mesh
networks. The novelty of this model is that, by only manipulating the edges of an auxiliary …
