This demonstration shows the hardware prototype of the IPclip (IP calling line identification presentation) mechanism for IPv6 networks. IPclip is a mechanism, which provides Trust-by-Wire in IP-based networks by adding trustworthy location information to IP packets. It is implemented on an FPGA development board and configurable at runtime via a graphical configuration tool. We show IPclip's basic...
During the last decades, the Internet has steadily developed into a mass medium. The target group radically changed compared to, e.g., the 90s. Because virtually everyone has access to the Internet, threats due to insecurity and anonymity reach critical levels and have to be tackled by both carriers and Internet Service Providers. Regaining trust-by-wire, comparable to classic fixed line telephones,...
During the last decades, the Internet has steadily developed into a mass medium with millions of users. On the one hand, newfangled services replace traditional ones. Naturally, these are thereby expected to offer at least the same features as their classical pendants, e.g., when VoIP replaces traditional fixed line telephone networks. On the other hand, the requirements on network infrastructures...
During the last years, the Internet has grown into a mass-medium for communication and information exchange. Millions of people are using the Internet for business and in social life. Users can be reached easily and cost-effectively. Unfortunately the Internet's open structure is the reason for its frequent misuse for illegal and criminal actions such as dissembling phishing attacks. Thus, anti-phishing...
In modern network applications and especially in Access Networks, the demands towards functionality and throughput are rising permanently. Furthermore, telecommunication carriers have different and changing requirements towards Access Network equipment. They are thus demanding a great deal of flexibility in IP-DSLAMS. To satisfy these various needs, highly flexible and particularly high performing...
During the last years, networks-on-chip (NoCs) have become a true alternative for the design of complex integrated systems-on-chip (SoC). Much effort has been spent for research on functionalities, mechanisms, and quality-of-service (QoS) features in NoCs. Hence, a broad and multi-faceted design space exists but leaves open, which mechanisms and design paradigms actually tip the scales for the chosen...
This paper investigates the energy problem in sensor networks. After random deployment, nodes have to observe a region and transmit their sensor data to a central station. By checking redundancies in coverage and transmission with our XGAF algorithm presented here it is possible to shutdown the majority of nodes into sleep mode. Computation reduction in sleeping nodes and reduced communication results...
The Internet is omnipresent. Everyone uses the Internet for information retrieval and communication. It is part and parcel of everyday life and culture. This is also true for all levels of preschool and academic education as well as on-the-job training. Currently, providing learning objects on an electronic and personalized base is widely favored and - in the meantime-common practice. We present LoGen,...
Today, an increasing number of customers subscribes for a high bandwidth Internet access. But not only communication speed is demanded. Quality-of-service moves more and more into the customers' focus. Both carriers and Internet Service Providers (ISPs) have increasing requirements derived from new services they want to offer to their customers. We present a new hardware solution is presented, which...
Dealing with uncertainty is an important issue in a broad range of research fields and industrial applications. For example with outer space missions or unmanned vehicles in perilous environs, today's and future systems have to adapt to changing environmental conditions. But high specialization of today's systems also results in decreased robustness and flexibility. These systems show high performance...
Managing reconfigurable hardware resources at runtime is expected to be a new task for future operating systems. But due to the mixture of parallel and sequential parts of dynamically reconfigurable applications, it is not entirely clear so far, how to use and to program such systems. A new interpretation of dynamically reconfigurable applications is presented. It is shown, that the parallel computing...
Partial dynamic reconfigurability of modern FPGAs holds the potential of realizing autonomous and highly flexible systems-on-chip (SoC). Current devices can be configured with several partial bitfiles and replace particular ones on demand. But these precompiled bitfiles seriously lack flexibility: they are hardly relocatable and not adjustable. In other words, they are tied to their original functional...
