基于IP业务的网络性能目标 |
本建议书定义了网际协议网络性能参数目标网络业务质量(QoS)类别。两个类别包含临时性能目标。这些类别旨在作为网络提供商之间以及终端用户和其网络提供商之间达成协议的基础。
附录一提供了异步传输模式(ATM)如何致辞后IP层性能的信息。附录二讨论了定义IP延迟变化的可选方案。附录三提供了ITU-T Y.1541用以测试QoS目标可行性的假定参考路径(HRP)。附录四给出了包延迟变化的计算示例。附录五讨论了IP测试时必须考虑的问题。附录六描述了本建议书与IETF-定义的QoS管理机制之间的关系。附录七给出了附录三假定参考路径语音传输质量的预测。附录八讨论了数字电视传输在IP网络上的传输。附录九预测了在兼容于ITU-T Y.1541目标的路径上传输控制协议(TCP)的文件传送性能。附录十给出了用户网络接口至用户网络接口(UNI-UNI)之间用于性能预测的多段合并延迟变化测量计算示例,附录十一预测了数字电路仿真包丢失要求。 |
