本文研究了反向链路（或上行链路）的带宽和可靠性作为实时业务的性能指标。在真实的网络环境中，采用两水平完全析因实验设计（DOE）研究了数据包大小、数据流速率、时间和缓冲区大小四个因素对网络带宽和可靠性的影响。对每个因素的两个极端情况进行了测试，并进行了统计分析，以表征不同因素及其相互作用如何影响带宽和可靠性。本研究的重要性说明在最佳的信道选择机制，适当的数据包大小，数据流速率和缓冲区大小可以选择，以达到最佳的效果。
The bandwidth and reliability of the reverse link (or uplink) as the performance metrics of real-time traffic are studied in this paper. A two-level full factorial design of experiment (DOE) was conducted to identify the impact on the bandwidth and reliability of four factors: packet size, data streaming rate, time of the day, and buffer size in a real network environment. Two extreme cases for each factor were tested and statistical analysis is performed to characterize how different factors and their interactions may affect the bandwidth and reliability. The importance of this study is illustrated in the optimal channel selection mechanism where appropriate packet size, data streaming rate and buffer size can be chosen to achieve the best result.
