Abstract:
In this paper, we propose a framework to reduce the aggregate power consumption of the Internet using collaborative approach between Autonomous Systems (AS). We identify the low-power paths between the AS and then use Traffic Engineering techniques to route packets along the paths. Such low-power paths can be identified by using the available power-to-bandwidth (PWR) ratio as an additional constraint in the Constrained Shortest Path First algorithm. For re-routing the data traffic through these low-power paths, the inter-AS Traffic Engineered Label Switched Path that spans multiple AS can be used. Extensions to the Border Gateway Protocol can be used to disseminate the PWR ratio metric among the AS thereby creating a collaborative approach to reduce the power consumption. Since calculating the low-power paths can be computationally intensive, a graph-labelling heuristic is also proposed. This heuristic reduces the computational complexity but may provide a sub-optimal low-power path. The feasibility of our approaches is illustrated by applying our algorithm to a subset of the Internet. The techniques proposed in this paper for the inter-AS power reduction require minimal modifications to the existing features of the Internet.
