摘　　要：在网络数据传输速率发生变化的情况下,针对有线和无线混合网络研究网络服务质量(Quality of Service,QoS)的问题。网络的QoS在稳定性及接收数据量方面分别是通过时延抖动和吞吐量来衡量的,文中采用NS2仿真技术对有线和无线的混合网络进行研究,通过实验数据分析在数据传输速率发生变化的情况下网络的时延抖动和吞吐量的变化情况。结果表明,数据的传送速率对于网络的吞吐量和时延抖动指标均有明显影响,并具有确定性规律。In circumstances of data transmission rate changing in networks, the problem of Quality of Service （QoS） is researched for wired and wireless mixed networks. The stability and data quantity received of a network is quantified by delay jitter and through- put respectively, the wired and wireless mixed network is researched by NS2 simulation technology in this paper. As data rate changing, the changing situation of delay jitter and throughput is analyzed by experimental data. The results show that data transmission rate has significant influences on delay jitter and throughput of networks and there are deterministic rules,
