Optical burst switching (OBS) - a new paradigm for an optical Internet

This work presents an estimation of the global electricity usage that can be ascribed to Communication Technology (CT) between 2010 and 2030. The scope is three scenarios for use and production of consumer devices, communication networks and data centers. Three different scenarios, best, expected, and worst, are set up, which include annual numbers of sold devices, data traffic and electricity intensities/efficiencies. The most significant trend, regardless of scenario, is that the proportion of use-stage electricity by consumer devices will decrease and will be transferred to the networks and data centers. Still, it seems like wireless access networks will not be the main driver for electricity use. The analysis shows that for the worst-case scenario, CT could use as much as 51% of global electricity in 2030. This will happen if not enough improvement in electricity efficiency of wireless access networks and fixed access networks/data centers is possible. However, until 2030, globally-generated renewable electricity is likely to exceed the electricity demand of all networks and data centers. Nevertheless, the present investigation suggests, for the worst-case scenario, that CT electricity usage could contribute up to 23% of the globally released greenhouse gas emissions in 2030.

On Global Electricity Usage of Communication Technology: Trends to 2030

The current fast-growing Internet traffic is demanding more and more network capacity every day. The concept of wavelength-division multiplexing has provided us an opportunity to multiply network capacity. Current optical switching technologies allow us to rapidly deliver the enormous bandwidth of WDM networks. Photonic packet switching offers high-speed, data rate/format transparency, and configurability, which are some of the important characteristics needed in future networks supporting different forms of data. In this article we present some of the critical issues involved in designing and implementing all-optical packet-switched networks.

Advances in photonic packet switching: an overview

This paper presents a novel architecture for an edge optical packet router. An IP/optical packet transceiver mechanism performing class based optical packet transmission as well as receiving asynchronous and variable length optical packets is demonstrated. (2 pages)

Hybrid IP/optical packet transceiver mechanism for wavelength routed asynchronous optical packet switched networks

All-optical routing of 25 Gbit/s WDM signals across two cascaded optical cross connects (OXCs) with a penalty of only 06 dB has been demonstrated using tuneable wavelength converters and a passive WDM router

All-optical routing using a 12×12 passive InP wavelength selective router and tuneable wavelength conversion

Summary form only given. This report presents for the first time a comprehensive theoretical study on the laser-controlled Er-doped fiber amplifiers (EDFAs). Explicit analytical expressions are derived for the calculation of amplifier gain and noise spectra, critical input signal power; and optimum amplifier length without resorting to any numerical methods of analysis.
