WebPacket classiﬁcation A packet header is a ﬁxed-size bit vector X = (x 1;:::;x n), where a Boolean variable x i corresponds to the ith bit of the header. Individual header bits are … WebSep 12, 2024 · Packet classification has been studied for decades; it classifies packets into specific flows based on a given rule set. As software-defined network was proposed, a recent trend of packet classification is to scale the five-tuple model to multi-tuple. In general, packet classification on multiple fields is a complex problem. Although most existing …

WebMay 25, 2014 · Most of packet classification algorithms on general purpose processors fall into two categories: decision-tree-based and decomposition-based algorithms. Decision-tree-based algorithms recursively cut the entire space into smaller sub-regions to locate the packet header. However, searching in a large tree requires too many memory accesses; it … 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 ...
