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 …

Cloud-fog computing emerges to satisfy the low latency and high computation requirements
of Internet of Things (IoT) services. Elastic optical networks (EONs) are excellent substrate …

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 …

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 …

The interconnection of all things is developing a new diagram of future information networks.
However, it is difficult to realize future applications with only one single technique …

With the rapid development of information and communication technology (ICT), the demand
for flexible and cost-effective network services (NSs) is growing exponentially. Network …

In aggregation networks, the traffic patterns resemble hub-and-spoke characteristics, with a
few hub nodes connecting several leaf nodes to the outside of the networks. The use of …

This paper proposes the design of energy and spectrum efficient, survivable Routing and
Spectrum Allocation (RSA) scheme for regenerator aware Elastic Optical Network (EON) …

Due to the development of broadband access technologies including FTTx and 5G, the
traffic in metro and core networks is forecasted to be more dynamic. To support this …
