IP服务的网络性能目标 |
![](images/pdf.png) |
本建议书定义网络服务质量(QoS)等级以及网际协议网络性能参数的目标。等级中的两个包含有暂定的性能目标。这些等级旨在在网络提供商之间以及终端用户和它们的网络提供商之间,作为做出约定的基础。
附录一提供ATM如何能支持IP层性能的有关信息。附录二讨论定义IP时延变化的不同方法。附录三提供了假设参考路径,可针对它测试Y.1541 QoS目标的可实现性。附录四给出了计算包时延变化的例子。附录五讨论当进行IP测量时须考虑的问题。附录六描述本建议书和IETF定义的QoS管理机制的关系。附录七给出了对语音传输质量在附录三假设参考路径情况下的估计。附录八讨论在IP网络中数字电视的传送。附录九对符合Y.1541目标的路径上TCP文件传送的性能做出估计。
