摘要
TCP是计算机网络的最重要协议之一,但由于其实现机理复杂,因此成为计算机网络教学的难点。提出基于NS2的TCP教学演示,能针对连接建立、确认机制及拥塞控制等关键TCP协议实现机理进行分析和演示,增强教学效果。
TCP is one of the most important protocols of computer networks,but as its implementation mechanisms are complex,the TCP teaching has become a difficult point in computer network teaching.The TCP teaching demonstration based on NS2 is presented,which can analyze and demonstrate the TCP protocol’s key implementation mechanisms,such as connection establishment,acknowledgement scheme and congestion control etc.,and thus can improve teaching effectiveness.
