In order to classify packet, we propose a novel IP classification based the non-collision hash and jumping table Trie-tree (NHJTTT) algorithm, which is based on non-collision hash Trie-tree and Lakshman and Stiliadis proposing a 2-dimensional classification algorithm (LS algorithm).The core of algorithm consists of two parts: structure the non-collision hash function, which is constructed mainly based on destination /source port and protocol type field so that the hash function can avoid space explosion problem; introduce jumping table Trie-tree based LS algorithm in order to reduce time complexity.The test results show that the classification rate of NHJTTT algorithm is up to 1 million packets per second and the maximum memory consumed is 9 MB for 10 000 rules.
