通信业务质量:框架和定义
本建议书给出了通信服务质量的框架和定义,在整个ITU-T建立统一的服务质量方法,并消除因不同的框架和定义不一致造成的混乱。整个通信行业都需要提高服务质量方面的一致性,尤其是在国际电联内部和外部的IP相关领域。本建议书提供了一个实用的“自上而下”的路径,从一般的质量定义(ISO 8402)到QoS定义(ITU-T E.800建议书)到网络性能(ITU-T I.350和Y.1540建议书)到服务质量(QoS定义矩阵ETSI ETR 003)的所有组成部分的功能分解。此外还介绍了使该定义和框架对每个人都具有意义的QoS四个视角:用户、供应商、网络运营商、服务提供商等。这种整体方法被认为是非常有用的,因为它鼓励在自上而下的QoS的框架和定义与自下向上的网络元素的运行方法之间形成一致的、统一的映射。使用这种方法的优点是,它不仅有助于确定与QoS相关的问题,同时有利于从多个视角对问题进行量化:用户的(例如调查和主观测试)和服务提供商的(网络测量)。这有助于保证在一个领域(如供应商)解决问题的同时也解决了其他领域(如用户)的问题。
