Low-rate denial-of-service attack is a novel category of DDoS attacks. The paper defines defense performance as metric to analyze whether the degree of distribution of attack sources impacts the LDoS attack greatly. From the result of simulation on NS2, the deeper degree of distributed, the better defense performance of Droptail (passive queue management), and the worse defense performance of RED...
In the field of data mining, clustering is one of the important methods. K-Means is a typical distance-based clustering algorithm; 2-tier clustering should implement scalable clustering by means of dividing, sampling and knowledge integrating. Among those tools of distributed processing, Map-Reduce has been widely embraced by both academia and industry. Hadoop is an open-source parallel and distributed...
Timed event is an essential part of concurrent actor interaction. This paper presents predictable time-centric semantic framework for designing actor-oriented embedded control software on the distributed platform, which reduces complexity by separating actor's data-centric computational parts from timed interaction among actors. Actors are concurrent components. Signal, timed metric distance and causality...
