Abstract

The invention provides a method and device for processing a network data packet and a storage medium. The method comprises the steps that a first matching vector is generated according to a first classification rule set and packet header information of a network data packet, and all elements in the first matching vector are used for representing whether the network data packet is matched with allclassification rules in the first classification rule set or not; a first report vector is generated according to a first priority coding matrix and the first matching vector, and all elements in thefirst priority coding matrix are used for representing the priority high-low relation between all classification rules in the first classification rule set; the first report vector is output so as toforward the network data packet according to the classification rule with the highest priority matched with the network data packet. According to the method disclosed in the embodiment of the invention, the classification of the network data packets can be realized more flexibly.

Description

technical field [0001] The present invention relates to the field of network technology, and more specifically, to a method, device and storage medium for processing network data packets. Background technique [0002] The wide application of network packet classification (Packet Classification) technology in network functions such as switches, routers, firewalls and deep packet inspection makes it a vital part of network technology. The network packet classification algorithm is an algorithm for classifying and processing network data packets with given classification rules. The network packet classification algorithm first performs protocol analysis and field extraction operations on network data packets, and then classifies network data packets according to the protocol type and classification field. At the same time, the network packet classification algorithm also needs to consider how to add new rules to the classification rule set, that is, how to update the classific...
