Introduction (1/2) TCAM-based solutions can reach high speed performance, while TCAM-based solutions suffer from a range-to-prefix conversion problem, making it difficult to support large and complex rule sets. Bloom-Filter-based algorithm can process prefix-type rules well, it is not good at range- type rules. Computer & Internet Architecture Lab CSIE, National Cheng Kung University 3

Introduction (2/2) BTPCF (Binary Tree Packet Classification based on FPGA). Builds a binary decision-tree data structure by preprocessing the classifier. When a packet arrives, the classification algorithm traverses the decision tree to find the leaf node. Computer & Internet Architecture Lab CSIE, National Cheng Kung University 4
