3.2 Terms defined in ITU-T Rec. X.606 | ISO/IEC 14476-1

This Recommendation | International Standard is described based on the concepts and terms developed in the specification of simplex multicast transport on ECTP (ITU-T Rec. X.606 | ISO/IEC 14476-1).

• a) application;
• b) packet;
• c) sender;
• d) receiver;
• e) tree;
• f) parent; and
• g) child.

3.3 Terms defined in this Recommendation | International Standard

For the purposes of this Recommendation | International Standard, the following definitions apply:

• a) QoS monitoring : Is the protocol operation that is used to diagnose the current connection status. For QoS monitoring, each receiver is required to measure the experienced parameter values and to report them to sender. Sender aggregates the status information reported from receivers.
• b) QoS maintenance : Is the protocol operation that is used to maintain the connection status at a desired QoS level. Sender takes QoS maintenance actions based on the monitored status information.
