Title: Method for classifying network packet on basis of equal length and equal density segmentation
Inventor: LI HUI
IPC: H04L12/70
Filed: 2018-03-30
Abstract: The present invention relates to a method for classifying a network data packet on the basis of equal length and equal density segmentation, used for lookup of a quintuple and an OpenFlow flow table, and featuring dynamic incremental update. The method comprises: a. partitioning an original classification flow table into multiple sub-flow tables according to size characteristics of dimension values, and selectively merging the sub-flow tables obtained by partitioning; b. for each merged sub-flow table, adopting a segmentation technique combining equal length and equal density to construct a decision tree lookup structure; c. during a packet lookup process, extracting corresponding domain values of packets to look up each decision tree, so as to obtain a matching result with the highest priority; and d. maintaining a relationship between the classification flow table and the decision tree to realize a dynamic incremental update. A hybrid segmentation-based decision tree structure is constructed from partitioned sub-flow tables by means of flow table partitioning, thereby effectively resolving the issue of rule copy expansion in a decision tree, and achieving high-speed network packet classification while ensuring low memory consumption by algorithms.
