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 emerging software defined networking (SDN) paradigm separates the data plane from
the control plane and centralizes network control in an SDN controller. Applications interact …

This article reports the work on next generation transponders for optical networks carried out
within the last few years. A general architecture supporting super-channels (ie, optical …

Emerging technologies such as spectrally efficient multicarrier higher order modulation and
bandwidth variable wavelength selective switches have led to a change in the optical …

Elastic flexgrid optical networks (FG-ON) are considered a very promising solution for next-
generation optical networks. In this article we focus on lightpath adaptation under variable …

Utilizing the dormant path diversity through multipath routing in the Internet to reach end
users-thereby fulfilling their QoS requirements-is rather logical. While offering better …

In this work we detail the strategies adopted in the European research project IDEALIST to
overcome the predicted data plane capacity crunch in optical networks. In order for core and …

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 …

The sliceable optical transponder, which can transmit/receive multiple optical flows, was
recently proposed to improve a transponder's flexibility. The upper-layer traffic can be …

Traffic grooming has evolved to present some new features in sliceable bandwidth-variable
transponder enabled elastic optical networks (SBVT-EON). One of the new features is …
