  We model the evolution of the Internet at the Autonomous System level as a
process of competition for users and adaptation of bandwidth capability. We
find the exponent of the degree distribution as a simple function of the growth
rates of the number of autonomous systems and the total number of connections
in the Internet, both empirically measurable quantities. This fact place our
model apart from others in which this exponent depends on parameters that need
to be adjusted in a model dependent way. Our approach also accounts for a high
level of clustering as well as degree-degree correlations, both with the same
hierarchical structure present in the real Internet. Further, it also
highlights the interplay between bandwidth, connectivity and traffic of the
network.
