在本文中，我们讨论了与IP/ATM环境中QoS参数映射相关的问题。我们在恒定TP包速率下进行了初步实验，在AAL5中进行分割后，产生了一个抖动的CBR细胞流。我们使用这个流来研究参数转换对应用程序接收到的QoS的影响。结果表明，翻译确实对性能有重大影响，特别是对细胞损失。还有成本问题，因为需要较大的缓冲区才能达到可接受的性能水平。
In this paper we discuss issues relating to the mapping of QoS parameters in an IP/ATM environment. We conduct preliminary experiments with constant TP packet rate, which after segmentation in AAL5, generates a jittered CBR cell stream. We use this stream to investigate the effect of parameter translation on the QoS received by the application. Results indicate that translation does have a significant impact on performance, in particular, on cell loss. There are also cost implications, as large buffers are required to achieve an acceptable level of performance.
