Abstract

The Network Tomography technology based on RTCP feedback for network monitoring and management is significant. The current RTCP feedback mechanism is defined in RFC3550. In this paper, the RTCP Extended Report (XR) feedback mechanism has been studied. The paper analyses the relationship between the feedback interval and RTCP packet size and the size of the multicast session, points out the shortage of the current feedback mechanism, and puts forward animproved encoding method. Based on the RTCP unicast feedback model, using reasonable encoding XR packets can reduce the feedback bandwidth and promote the feedback rate.
