— 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. Popular applications that serve content over these networks in the upstream direction, such as peer-to-peer (P2P)(More)
Over the years, the demand for high bandwidth services, such as live and on-demand video streaming, steadily increased. The adequate provisioning of such services is challenging and requires complex network management mechanisms to be implemented by Internet service providers (ISPs). In current broadband network architectures, the traffic of subscribers is(More)
Broadband Remote Access Servers (BRASes) are crucial middleboxes in DSL access networks, providing the first IP point in the network for subscribers and enforcing operator policies. The number of functions provided by BRASes, combined with the key role they play in the network, means that these devices are expensive, difficult to change, and constitute a(More)
More and more laboratories are forced to document evidently that experimental results were achieved compliant with the regulatory of Good Laboratory Pratice (GLP). Thus, also for the imaging plate technique, which is widely used in whole-body autoradiography, it is necessary to provide procedures for formal validation and continuous quality control.(More)
Since their emergence peer-to-peer (P2P) applications have been generating a considerable fraction of the overall transferred bandwidth in broadband networks. Residential broadband service has been moving from one geared towards technology enthusiasts and early adopters to a commodity for a large fraction of households. Thus, the question whether P2P is(More)
Standardization organizations play a major role in the telecommunications industry to guarantee interoperability between vendors and allow for a common ground where all players can voice their opinion regarding the direction the industry should follow. In this paper we review the current activities in some of the most relevant standardization bodies in the(More)
Broadband Remote Access Servers (BRASes) play a crucial role in today's networks, handling all traffic coming from access networks (e.g., DSL traffic), applying operator policies and providing the first IP point in the network. It is perhaps unsurprising then, that these are expensive, proprietary, difficult-to-upgrade boxes. They also represent a large,(More)

The smartphone revolution together with cost-efficient wireless access technologies has lately changed the landscape for smart home environments to a large extent. Moreover, large flat screens, new capturing devices, and large digital media libraries have also changed the way smart home environments are used. We present and evaluate an architecture for(More)
