摘　　要：首先介绍了链路聚合(Link Aggregation)的应用背景和基本概念,以及实现链路聚合的LACP(Link Aggregation Control Protocal)协议的内容和原理,其中LACP状态机控制LACP协议运行,是确保LACP协议链路聚合运行的关键,最后说明了利用有限状态机在PTN智能接入终端上实现链路聚合的方案。经验证,动态聚合功能正常运行,达到测试要求。In this paper, the background and the basic concepts of link aggregation technology are firstly introduced. Then ,the contents and principles of LACP are described. LACP state machine module controls the operation of the LACP. It is the core and key module to ensure LACP work effectively. Finally the use of finite state machine is illustrated to realize the dynamic link aggregation on the intelligent access terminal based on PTN. In testing, the function of dynamic link aggregation operates normally, and achieve the requirements of test.
