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 …

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 …

Due to the ubiquitous use of the Internet and huge proliferation of network devices, the
energy consumed by today's networks has increased significantly, implying the need for …

As the Internet grows in capacity, the energy consumption of Information and
Communication Technologies (ICT) are significantly increasing. Significant research efforts …

This paper proposes a static Routing and Spectrum Allocation (RSA) method to design low-
power elastic optical networks. In the elastic optical networks, data are transmitted via …

We study the energy-efficient routing and wavelength assignment (RWA) problem in
translucent WDM networks, taking into account transmission limits of optical signals and the …

In this paper, we propose a static lightpath establishment method to design low‐power all‐
optical networks under the constraint of four‐wave mixing (FWM). Since the FWM causes …

In multifiber all-optical networks, optical amplifiers are used for amplifying multiple optical
signals with different wavelengths in fibers. An optical amplifier operates when any of light …

This work seeks to improve the energy efficiency of backbone networks by automatically
managing the paths of network flows to reduce the over-provisioning. Compared to …

在低负载时断开网络拓扑部分链路是IP over WDM 光网络中一种有效的节能方法,
但链路断开时段的选择对IP over WDM 光网络的阻塞率和节能效果有较大的影响, 对此 …
