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 …
While the Internet has radically changed business and society over the past decades, its architecture has hardly evolved. Therefore, pressure from new applications, business models and networking technologies are distorting the architec- ture to a …
ScatterWeb, a distributed, heterogeneous platform for the ad-hoc deployment of sensor networks offers hardware together with open, fully documented software for the deployment of embedded sensor networks. Already low power by design, the sensor nodes …
