Today's science is more and more driven by collecting and evaluating increasing amounts of data. Utilizing Scientific Workflows is one suitable method how to organize processing pipelines for this purpose. In this work, we show that performance improvements on the execution of existing workflows can be achieved, if the conditions for starting selected tasks with certain data access characteristics...
In order to process network packets at high rates, network functions like routing or firewalling require specialized hardware like TCAMs (Ternary Content Addressable Memories), ASICs (Application Specific Integrated Circuits), or GPUs (Graphics Processing Units). Such hardware must be fast enough to process packets at line rate, and furthermore, it must be programmable in order to update the packet...
Network packet classification plays a pivotal role in packet-switched networks; it is at the heart of many functions including firewalling, QoS routing, and OpenFlow-based switching. However, packet classification is a hard problem, as packets must be classified within a short time frame. Existing classification techniques use sophisticated data structures which are traversed by generic search algorithms—that...
