Two major technologies enabling the multimedia communication are increased media bandwidth, and the increased processing power of the end systems. In spite that most of the multimedia communication take the form of the multiparty, researches on the group features and group classification and group management are insufficient compared to that of processing, and transferring of the media data. Quality of service(QoS) is negotiated at connection setup time, and assumed to be guaranteed by network afterwards. But, to guarantee the negotiated QoS, it needs to control transfer rate at the sender side based on the receivers' reception report. In this paper, we propose a method to classify and manage groups according to its features. And we also present a media manager which guarantees QoS during the communication and evaluate its performance when applied to Desktop Conference System. All of the functions of the group manager and the media manager are implemented.
