—Continuous growth in network link rates poses a strong demand on high speed IP lookup engines. While Ternary Content Addressable Memory (TCAM) based solutions serve most of today's high-end routers, they do not scale well for the next-generation [1]. On the other hand, pipelined SRAM-based algorithmic solutions become attractive. Intuitively multiple(More)
—Packet classification is a fundamental enabling function for various applications in switches, routers and firewalls. Due to their performance and scalability limitations, current packet classification solutions are insufficient in addressing the challenges from the growing network bandwidth and the increasing number of new applications.

In this paper we present a novel architecture for high-speed and high-capacity <i>regular expression matching</i> (REM) on FPGA. The proposed REM architecture, based on nondeterministic finite automaton (RE-NFA), efficiently constructs <i>regular expression matching engines</i> (REME) of arbitrary regular patterns and character classes in a uniform(More)
—Lookup engines for various network protocols can be implemented as tree-like search structures. Mapping such search structures onto static random addressable memory (SRAM)-based pipeline architectures has been studied as a promising alternative to ternary content addressable memory (TCAM) for high performance lookup engines in next generation routers.(More)
