Abstract

The invention provides a method and a device for classifying network packet rule sets. The method comprises the following steps: determining a preset number of division significance bits from the network packet rule sets based on a preset method; generating a mask vector based on the preset number of division significance bits; and dividing the network packet rule sets according to the mask vector. According to the method provided by the invention, multiple network packet rule sets can be converted into a single network packet rule set by the mask vector, thereby greatly reducing the computation complexity, and thus the problem of slow classification speed of the network packet rule sets in related technology can be solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for classifying network packet rule sets. Background technique [0002] With the development of the Internet, the traditional routing technology can no longer meet the needs of network services. Therefore, the network packet classification technology emerges as the times require. The network packet classification technology refers to the process of classifying the network packets according to the information in the network packets and according to the preset network packet rule set (the network packet rule set includes a plurality of network packet rules). The division of network packet classification rules generates multiple rule subsets by preprocessing the preset rule set, which can effectively improve the search speed of network packet rules during network packet classification and improve the performance of network packet classificati...
