Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Current networks integrate multiple transport technologies to exploit their relative advantages and different functionalities, and these are multilayer networks combining IP/ATM/SDH/WDM technologies. To provide end to end survivability, different restoration mechanisms at different layers must be combined efficiently in order to achieve fast restoration, maximum availability and minimum restoration cost. This paper describes the key issues associated with the implementation of restoration in a multilayer network. Moreover, the 'best' strategies proposed so far are presented and the current state of standardisation is discussed. Finally, current unresolved issues and open problems are highlighted.
