Information technology -- Enhanced communications transport protocol: Specification of QoS management for simplex multicast transport

ISO/IEC 14476-2:2003 is an integral part of ITU-T Recommendation X.ectp ISO/IEC 14476 having the main title of Enhanced communications transport protocol, which is a family of protocol specifications designed to support multicast transport services.

ISO/IEC 14476-1 provides a specification of various protocol operations for simplex multicast transport. Those protocol operations include connection management such as connection creation/termination and connection pause/resume, membership management such as late join, user leave and membership tracking, and error control for multicast data transport such as error detection and recovery.

ISO/IEC 14476-2:2003 provides a specification of QoS management for accomplishing desirable quality of service in simplex multicast transport connection.

ISO/IEC 14476-2:2003 describes the following QoS management operations:
a) QoS negotiation For QoS negotiation, this specification assumes that a desired QoS level for multicast application service can be expressed in terms of a set of QoS parameters. QoS negotiation is performed via exchange of control packets between sender and receivers. Sender proposes the target values of QoS parameters obtain
