Machine learning (ML) algorithms have been shown to be effective in classifying a broad range of applications in the Internet traffic. In this paper, we propose algorithms and architectures to realize online traffic classification using flow level features. First, we develop a traffic classifier based on C4.5 decision tree algorithm and Entropy-MDL (Minimum Description Length) discretization algorithm...
PageRank is a fundamental graph algorithm to evaluate the importance of vertices in a graph. In this paper, we present an efficient parallel PageRank design based on an edge-centric scatter-gather model. To overcome the poor locality of PageRank and optimize the memory performance, we develop a fast and efficient partitioning technique. We first partition all the vertices into non-overlapping vertex...
Conventionally, regular expression matching (REM) has been performed by sequentially comparing the regular expression (regex) to the input stream, which can be slow due to excessive backtracking (smith:acsac06). Alternatively, the regex can be converted to a deterministic finite automaton (DFA) for efficient matching, which however may require an extremely large state transition table (STT) due to...
