摘　　要：列举了基于QoS套接字的两种多媒体业务,其中一种基于UDP协议,另一种基于TCP协议。实验结果表明,增加了QoS套接字后,两种多媒体业务的性能都得到了较大的改善,但是由于TCP和UDP本身特性的不同,两种多媒体业务性能改善的程度有所不同。最后对试验结果进行了讨论并得出了一些有意义的结论。In the paper two appli cations of multimedia services using QoS Socket are given.One is based on UDP and the oth er is based on TCP.The re sults of tests show using QoS Socket the performances of the two kinds of multimedia services im prove apparently.How ever,because the differences between TCP and UDP there exist the diversities of improved perfor-mances between the two kinds of multi media services.Finally the results of tests are discussed and some meaning conclu-sions are drawn.[
