The most common broadband access technology today is the (Asymmetric) Digital Subscriber Line (A)DSL. As the name implies, ADSL allocates the bandwidth of upstream and downstream asymmetrically, significantly favoring the downstream direction. …
The stress on today’s inter-domain routing system is constantly and sharply increasing. The mere size of the Internet, operational practices and a number of limitations of the routing protocol itself worsen the scaling behavior of this funda- mental …
In this paper, we outline a fast approach to build a model of the Internet’s AS-level routing topology. More important than the construction process itself is the detailed analysis of the model’s accuracy by com- paring it against a vast amount of …
