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.
