We model the end to end delay and energy efficiency in the optical network architecture
NGREEN. As the architecture is based on an optical ring, the random part of the delay …

The paper reviews the extent to which sleep mode (SM) green routing strategy in green
networking impacts on the reliability as well as lifespan of optical networking devices. We …

This paper reviews and analyzes the extent to which sleep mode (SM) green routing impacts
on operational energy savings as well as performance of optical backbone networks. First …

All-optical access-metro networks avoid costly OEO conversions which results in
subsequent reduction of infrastructure costs and improvement in energy-efficiency of the …

Energy saving is an important issue that should be taken into consideration when planning
telecommunication networks. In fiber–wireless access networks the potential for energy …

In this paper we propose and investigate an OTN/WDM network architecture for the transport
of Ethernet/CPRI flows in 5G scenario. The proposed solution allows for a dynamic …

The Compound Annual Growth Rate (CAGR) of Internet traffic volume lies in the 30-70%[1]
range. For several good reasons (to handle unexpected traffic spurts, link failures and traffic …

Communication networks continue to experience an increase in traffic volumes, number of
connected devices, and users. For this reason, the energy consumption due to the …

Significant part of the total energy consumption in distribution and core optical networks is
contributed by the energy consumption of Internet Protocol (IP) routers. In this paper, an …

We propose a multi-layer energy saving technique for optical core networks that aims at
reducing energy consumption by powering off components in different layers of the network …
