In this paper, we propose a framework to reduce the aggregate power
consumption of the Internet using a collaborative approach between
Autonomous Systems (AS). We identify the low-power paths among the AS
and then use suitable modifications to the BGP path selection
algorithm to route the packets along the paths. Such low-power paths
can be identified by using the available power-to-bandwidth (PWR)
ratio as an additional parameter in the BGP Path Selection Algorithm.
For re-routing the data traffic through these low-power paths, the
power based best path is selected and advertised as per the modified
algorithm proposed in this document. Extensions to the Border Gateway
Protocol (BGP) can be used to disseminate the PWR ratio metric among
the AS thereby creating a collaborative approach to reduce the power
consumption. 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. The
proposed techniques can be extended to other levels of Internet
hierarchy, such as Intra-AS paths, through suitable modifications.
