Extraction of network application's signatures is the key point of the Deep Packet Inspecting(DPI) system in the field of traffic classification.A method is provided to automatically extract the feature strings of different HTTP applications(network video,online games,SNS,etc).Firstly,the full packet data of HTTP application was combined into flows.Then,a hash based algorithm was used to extract the frequent strings.At last a common feature library was built to get individual feature strings out of frequent strings by matching each of them.
