A detailed survey of approaches reducing energy consumption of core networks is
presented in this paper. We consider a multilayer architecture, in which the optical layer can …

The year-by-year increase in electricity consumption significantly affects all nations today
from environmental, social, and economic perspectives. Various studies show that, among …

Optical networks can support a large amount of IP traffic in the next generation of networks
with energy efficiency awareness. However, the ever increasing demand of IP traffic also …

The tremendously large number of increasing Internet protocol (IP) packets call for quality of
service (QoS) guaranteed packets transmission with low-delay, high throughput, and high …

We tackle the problem of reducing power consumption in IP-over-WDM networks, targeting
the power-aware logical topology design (LTD). Unlike the previous work in the literature …

Virtual topology reconfiguration addresses the issue of overprovisioning in IP-over-WDM
optical backbone networks. Contrary to maintaining a static virtual topology, adapting the …

As global internet traffic continues to increase, network operators face challenges on how to
efficiently manage transmission in their networks. Even though attempts are underway to …

This paper proposes a solution to the trade-off between energy-efficiency and resilience in
communication networks, where the energy profiles express the decreasing return to scale …

The explosion of Internet traffic calls for quality of service (QoS)-guaranteed packet
transmission in wavelength division multiplexing (WDM) networks with high energy and …

This article proposes to solve the trade-off between energy-efficiency and resilience with a
focus on business mechanisms. Risk engineering is used as a foundation. Financial impact …
