Abstract Information and Communication Technologies (ICT) enjoys a reputation as a green technology by reducing the cost of information and service delivery and promoting such activities as teleworking, online conferences and training which reduce the need for workers to utilise air and road transport. The massive growth of the internet and the ubiquitous nature of internet enabled devices have raised the level of concern about the ICT sector energy consumption.
Utilisation of the transmission links between network devices is a focus for energy conservation. Improving link utilisation and reducing energy use during idle periods are topics for current research. Reducing the energy required to operate network devices such as switches, routers and concentrators is a key goal in the quest to make the network more energy efficient. Power management mechanisms that control and manage traffic flows and link operating states can lead to energy efficient network device and link operations and thereby improve the overall energy efficiency of the worldwide digital network. The trade-off between power management and performance is an important aspect of this research and an investigation has been carried out to identify energy savings that have a minimal effect on performance. A focus on identifying Quality of Service requirements for traffic streams in a differentiated service environment provides an approach that has led to a traffic priority transmission process that conserves energy.
The power management mechanisms introduced in this thesis propose traffic management based on traffic class, the link states being managed based on buffer utilisation and links being put into low power modes. By utilizing link interfaces (intermediary buffers) to facilitate device component burst operation (including the device link processor, storage and other links component) it was found that performance was improved whilst reducing power utilization.
This thesis addresses energy consumption in Ethernet Access Networks, investigates and validates existing models and proposes a novel method to improve the energy efficient operation of Ethernet links that incorporates prioritized traffic management.
