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 …

In this work we propose a strategy to minimize the impact of energy saving techniques on
the performance of an Internet Service Provider network. We study the problem of putting in …

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 …

Energy saving in telecommunications networks has become a well established topic in the
research community. We look at the electrical and optical layers of IP-over-WDM networks …

This work experimentally demonstrates how to control and manage user Quality of Service
(QoS) by acting on the switching on-off of the optical Gigabit Ethernet (GbE) interfaces in a …

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

This paper briefly describes the objectives of the TREND (Toward Real Energy-efficient
Network Design) Network of Excellence of the European Commission 7 th Framework …

IP-over-WDM optical mesh backbone networks handle most of the high-volume traffic that is
exchanged between access networks. Internet growth and the increase in bandwidth …

This paper discusses the issue of providing basic QoS in optical burst-switched WDM
networks. As in WDM networks, end-to-end connection demands are dynamic routes, it …
