High performance multi-field packet classification using bucket filtering and GPU processing

The literature review shows a trend to arbitrary number of multi-field packet classification is evolved from standard 5-tuple matching to support new applications like OpenFlow switch which processes upto 15 fields [1]. However, arbitrary number of multi-field packet classification becomes a great challenge regarding to performance, memory requirement, and update cost. In this paper, a high performance multi-field packet classification system is designed and implemented using bucket filtering and GPU processing.
