为了解决基于UDP协议的实时多媒体数据流与基于TCP协议的应用数据流共享有限的带宽问题,文中就如何能够获得更好的多媒体数据流的传输算法进行了研究.在对传统算法进行分析和参考有关算法的基础上,改进了IETF的友好TCP速率控制协议.利用C++语言在NS2上成功地实现了改进后的算法,并进行了仿真,取得了预期的效果.
In order to solve the problem that real time multimedia data streaming based on UDP can not share limited bandwidth with TCP,an algorithm is studied which can acquire better transmission for multimedia streaming.Based on analyzing the traditional algorithms and other related algorithms,the IETF(Internet Engineering Task Force) TCP friendly congestion control algorithm is improved,and it is implemented successfully with C++ language in NS2.According to the simulation,the anticipated result has been obtained.
