Dear all.
We are a bunch of researchers from the IIT (indian Institute of Technology)
Madras (chennai) on the east coast of india. We are submitting research work
that has been done on the subject of greening the internet. We have
published the following documents (series of documents) of how to reduce
the overall power consumption in the internet in an inter-AS and an intra-AS
scenario. We would like to get the comments from the members of this
esteemed group with regard to these documents.
We submit two drafts that have been made part of the rtgwg working group in
the ietf. These two drafts deal with inter-AS scenarios where a
collaborative approach among the Ases is sought to be achieved to reduce the
power consumption in the internet.
We are new to the IETF and the IRTF as well. So please let us know if we
have to re-submit these documents to the IRTF.
We would very much welcome your comments on these documents.
Thanks and regards,
Balaji venkat
The first document is as follows.
A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : Reducing Power Consumption using BGP
Author(s) : Shankar Raman

Filename : draft-mjsraman-rtgwg-inter-as-psp-03.txt
Pages : 24
Date : 2012-08-06
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 Traffic Engineering (TE) techniques 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
constraint in the Constrained Shortest Path First (CSPF) algorithm.
For re-routing the data traffic through these low-power paths, the
Inter-AS Traffic Engineered Label Switched Path (TE-LSP) that spans
multiple AS can be used. 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. Since calculating the low-power paths can be
computationally intensive, a graph-labeling 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. The proposed techniques can be extended to
other levels of Internet hierarchy, such as Intra-AS paths, through
suitable modifications.

Title : Reducing Power Consumption using BGP path selection

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.
