ISO/IEC 14476-6:2010提供了QoS管理规范，用于在n-plex多播传输连接中实现所需的服务质量。为此，本文描述了n-plex多播传输连接中的QoS管理操作，如QoS协商、QoS监控和QoS维护。ISO/IEC 14476-6:2010是ECTP-5（ITU-T Rec.X.608 | ISO/IEC 14476-5）的组成部分。所有协议组件，包括ITU-T Rec.X.608 | ISO/IEC 14476-5中规定的数据包格式和协议程序，在ISO/IEC 14476-6:2010中也有效。

ISO/IEC 14476-6:2010 provides a specification of QoS management for accomplishing a desired quality of service in n-plex multicast transport connections. For this purpose, it describes the QoS management operations in n-plex multicast transport connections such as QoS negotiation, QoS monitoring and QoS maintenance. ISO/IEC 14476-6:2010 is an integral part of ECTP-5 (ITU-T Rec. X.608 | ISO/IEC 14476-5). All of the protocol components, including packet formats and protocol procedures specified in ITU-T Rec. X.608 | ISO/IEC 14476-5, are also valid in ISO/IEC 14476-6:2010.
