摘　　要：描述了OMNeT++平台及基于它上的TCP/IP模型,在现有模型实现的基础上,通过试验验证改进后模型的可用性,对改进后的几项重要性能TCPDUMP输出、延迟确认和持续计时器进行阐述,比较了TCP友好性与非对称连接的性能,以TCP模型为例对几项重要的仿真结果进行分析,得出TCP模型的特征与不足.The OMNeT＋＋ package and TCP/IP model based on OMNeT＋＋ are presented. On the base of the existing implementation, the use of the improved model is proved through experiments. Several distinct features, such as TCPDUMP out,delayed acknowledgement and persistent timer are expounded. Furthermore, the friendliness of TCP and its performance of asymmetric connection are compared. Finally, several simulations are anlysed, taking TCP model as the example, and the advantages and disadvantages of TCP model are reached.
