—The TCP-Friendly Rate Control (TFRC) protocol manifests strong equality towards competing TCP or TCP-friendly flows. Although the RFC 3448 suggests that TFRC is suitable for multimedia, this equality is a great disadvantage in the case of transmitting multimedia over the TFRC. The TFRC emulates TCP-like congestion control using the TCP throughput equation.(More)
QoS guarantees for real-time HD video transmission can be assured by proper resource allocation. The TFD option of the IP protocol can be used to convey signaling information about required resources for a given transmission. In this paper the new traffic description for TFD option, based on analysis of scene changes, is presented. The traffic description(More)
The common practice in the MPEG video traffic modelling is to split video sequence into I, P and B subsequences and to model the traffic (generated by each subsequence) separately. This frame-oriented decomposition both allows avoiding non-homogeneity of modelling data and lead to linearisation of MPEG video traffic characteristics. In this paper, the(More)
ECN-capable TCP-friendly layered multicast mul-timedia delivery combines explicit congestion notifica-tion (ECN) with the TCP-friendly layered multicast scheme. TCP-Friendliness denotes that receiver–driven architecture behaves under congestion like the TCP protocol. Unlike well-known TCP-friendly proto-cols (TFRC, TFMCC, WEBRC), which use TCP(More)
