WebThis section describes the packet classification problem and surveys existing solutions. 2.1 Classification algorithms Packet classification is the process of locating a single rule that is satisfied by an input packet among a set of rules. A rule contains a few fields in the packet’s metadata. Wildcards defineranges, i.e., they match ... WebJan 10, 2024 · A typical kind of pre-processing used in packet classification algorithms is dividing, which includes ruleset splitting and search space cutting. The ruleset will split into subsets, and the search space will be cut into subspaces. How to divide the ruleset is the key to these pre-processing methods.

WebApr 1, 2001 · In general, packet classification on multiple fields is a difficult problem. Hence, researchers have proposed a variety of algorithms which, broadly speaking, can be categorized as basic... WebJan 29, 2024 · Packet classification is a fundamental function to support several services of software defined networking (SDN). Increasing complexity of the flow tables in SDN leads to challenges for packet classification on update and classification time. WebPacket classification algorithms are widely used in network security devices. As network speeds are increasing, the demand for hardware acceleration of packet classification in FPGAs or ASICs is growing. Nowadays hardware architectures can achieve multigigabit speeds only at the cost of large data structures, which can not fit into the on-chip ... how to increase recipe size
