ABSTRACT
Conventional wisdom has been that the performance limitations in
the current Internet lie at the edges of the network -- i.e last mile
connectivity to users, or access links of stub ASes. As these links
are upgraded, however, it is important to consider where new bot­
tlenecks and hot­spots are likely to arise. In this paper, we address
this question through an investigation of non­access bottlenecks.
These are links within carrier ISPs or between neighboring carriers
that could potentially constrain the bandwidth available to long­
lived TCP flows. Through an extensive measurement study, we
discover, classify, and characterize bottleneck links (primarily in
