Executive Summary

Real-time protocols such as Real-time Transport Protocol (RTP) and its companion protocol Real-time Transport Control Protocol (RTCP) are the solution for customers who have progressively come to desire real-time services. The characteristics of RTP and RTCP packets differ since they carry different content types, i.e., real-time data and control data, respectively. The standard approach assumes that RTP real-time data packets and RTCP control packets are classified into the same media-oriented service class. That might impact the Quality of Service (QoS) for real-time services with regard to network status.
