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 unprecedented growth of the global Internet traffic, coupled with the large spatio-
temporal fluctuations that create, to some extent, predictable tidal traffic conditions, are …

In recent years, OFDM has been the focus of extensive research efforts in optical
transmission and networking, initially as a means to overcome physical impairments in …

With the growth of Internet users' traffic demands, the efficient and cost-effective usage of
bandwidth and spectrum in optical networks plays an important role in improving service …

As optical networks continue to evolve to support increasing bandwidth demands, lightpaths
will take on different spectrum spaces as opposed to the current uniform 50-GHz grid …

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 …

How serious is spectrum fragmentation in an elastic optical network? It is addressed by the
tremendous provisioning gain achieved by eliminating a particular kind of fragmentation …

Compared to wavelength switched optical networks (WSON), flexgrid optical networks
provide higher spectrum efficiency and flexibility. To properly analyze, design, plan, and …

Emerging services and applications demanding high bitrate and stringent quality of service
requirements are pushing telecom operators to upgrade their core networks based on …

As elastic optical networks (EONs) are expected to convey high bitrate connections, a failure
in these networks causes vast data losses. Thus, addressing the problem of survivability in …
