(Introduction) Internet applications have traditionally been identified using well-known default server network-port numbers in the TCP or UDP headers. (Introduction) However this approach has become increasingly inaccurate. （Introduction） An alternate, more accurate technique is to use specific application-level features in the protocol exchange to guide the identification. （Introduction)Unfortunately deriving the signatures manually is very time consuming and difficult. （Introduction) In this paper, we explore automatically extracting application signatures from IP traffic payload content. （Introduction) In particular we apply three statistical machine learning algorithms to automatically identify signatures for a range of applications. (Method) The results indicate that this approach is highly accurate and scales to allow online application identification on high speed links. (Results)We also discover that content signatures still work in the presence of encryption. In these cases we are able to derive content signature for unencrypted handshakes negotiating the encryption parameters of a particular connection.(Conclusion) Keywords: Application signatures, application-level filter, machine learning 摘要分析范例（详细） 格式： 论文题目 期刊来源 摘要原文 分析（结构+时态、语态+句子功能） Example 2 A group recommendation system with consideration of interactions among group members Journal Source： EXPERT SYSTEMS WITH APPLICATIONS As on-line community activities have increased exponentially, the need for a group recommendation system has also become more and more imperative. Although, the traditional recommendation system has achieved great success in supporting individuals purchasing decisions, it is not suitable f
