Energy Efficient Content Distribution Optical Networks
Professor Jaafar Elmirghani, University of Leeds, UK

Summary

ICT networks continue to grow at 40% per year currently. It is estimated that these networks currently consume about 2% of the world energy, equivalent to the global aviation industry. At the present rate of growth, and driven by content, the network traffic is projected to grow by a factor of 30 in 10 years and by a factor of 1000 in 20 years which can lead to power consumption that is not sustainable. This talk will introduce new approaches for power minimisation in content distribution optical networks and in particular will examine the use of content caching to reduce power consumption, the design of energy efficient peer-to-peer content distribution networks and the design of distributed content clouds for energy efficiency. It will introduce a framework for designing energy efficient cloud computing services over IP/WDM core networks and discuss network-related factors, including centralisation versus distribution of clouds and the impact of demand, content popularity, and access frequency on the clouds’ placement, and cloud capability factors, including the number of servers, switches, and routers, and amount of storage required in each cloud. This talk builds summarises some of the work in the £5.9m EPSRC INTERNET programme grant, 2010-2015.

Industrial Panel (13:30 – 15:00)

SYMPOSIUM: Flexigrid optical networks
Chair: Pierpaolo Boffi, Politecnico di Milano, Italy

 

Symposium Abstract

To meet the dramatic growth in Internet demand, the optical industry must find new methods to increase the total capacity of existing fiber networks, ensuring economic efficiency and operational simplicity. Only by exploiting this combination the network providers can continue scaling network bandwidth, while limiting infrastructure improvement. Flexigrid transmission is proposed as the mean to use all the available fiber bandwidth in a real efficient way: the exploitation of an adaptive channel grid with wavelengths dynamically selected based on the data rate can allow the operators to upgrade their networks without disruptive and expensive investments. Nowadays, flexibility and dynamic scaling are feasible thanks to the advent of coherent modulation technologies that allow the spectral packing of WDM channels mainly when channel bit rates go beyond 100 Gb/s. Flexigrid networks can be considered as a valid recipe providing the most cost efficient way of delivering new and advanced services, pushing new opportunities for photonic research.
