PFLOWER

The State-of-the-art flow recognition techniques suffer from limitations of coarse-grained parallelims, large memory requirements, and limited throughput. The multi-core processor emerges as a promising approach for high-performance and scalalbe flow recognition. However, it imposes great challenges on parallelism and memory consumption. This project will study multi-core processor-based parallel flow recognition (pFlow), with particular focurses on parallel flow recognition architecture on the Multi-core platform, parallel signature matching algorithms and data structures, behavioral modeling and datamining, expeirmentation and evaluation. This project will improve the time/space efficiency of flow recogntion for network applications such as NIDS/NIPS, application-layer flow identifcation, and flow anomlay detection.
