摘　　要：能够标识出Internet上每个流所使用的应用层协议是一系列网络应用的前提和基础。然而随着网络的高速化和协议的复杂化,传统的基于端口识别应用层协议的算法已经不够准确,因此各种新的协议识别算法成为研究热点。本文介绍了协议识别问题的几个基本概念,将目前正在使用或研究的协议识别算法总结为三类并分析了各自的优缺点及关键技术和难点,最后指出了两个进一步研究的方向。The ability to accurately identify the Internet traffic associated with different application-level protocols is essential to a broad range of network applications. Due to high speed of network and complexity of new protocols, traditional port-based application-level protocol identification method is becoming much more inaccurate. Therefore, a variety of protocol identification algorithms become a research hotspot. In this paper, several basic concepts of applicationlevel protocol identification are introduced first; then the identification algorithms being used or researched now are classified into three categories; their main difficulties, advantages and disadvantages are also analyzed; finally two future research directions are presented.
