The design of most systems-on-a-chip (SoC) architectures rely on simulation as a means for performance estimation. Such designs usually start with a parameterizable template architecture, and the design space exploration is restricted to identifying the suitable parameters for all the architectural components. However, in the case of heterogeneous SoC(More)
The paper describes the need for early analysis tools to enable developers of today's system-on-a-chip (SoC) designs to take advantage of pre-designed components, such as those found in the IBM Blue Logic ® Library, and rapidly explore high-level design alternatives to meet their system requirements. We report on a new approach for developing high-level(More)
We present a design methodology for a modular network processor architecture that leads to a balanced, service-defined mix between programmable processor cores, configurable hardware assists, and specialized coprocessors. Whereas the processor cores address the flexibility and extendibility needs of the networking market, the hardware components offload the(More)
High-profile web servers often become the victim of web server overload Distributed Denial-of-Service (DDoS) attacks. Motivations of such attacks range from technical challenge (e.g. script kiddies) to financial profit (e.g. blackmailing the web server's owner). This paper presents the DIADEM Firewall architecture that allows an ISP to protect its customers(More)
Network processors use highly parallel architectures to improve performance and reach multi-gigabit line-speeds. In this paper, we emulate a pipeline in a highly parallel non-programmable industrial InfiniBand Host Channel Adapter to make a performance and bottleneck analysis and, at the same time, explore the potential of a pipelined architecture.(More)
Little attention has been paid to the evolutionary consequences of the colonizing dynamics and succession processes following glacier retreat. Here we studied hybrid populations that have recently formed and established on glacier forefields of the European Alps owing to secondary contact of a lowland colonizer with a subalpine species. We analyzed the(More)

Executive summary This document gives a detailed specification of all provided application programming interfaces (API) within the Diadem distributed firewall. Particularly the APIs for the firewall element and high-speed classification are explained and descriptions of the response API, notify API, monitor API and service API are presented. In addition,(More)
