Abstract:
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 consumed-power-to-available-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. A recent addition is the use of this method in AIGP
domains and also the use of power source data in the calculation of
low power paths using the BGP path selection algorithm.
