Multicast requires reliability in peer-to-peer or multiple-to-multiple communication services and such demand for reliability becomes more and more an important factor to manage the whole network. Communication method for multicast is a way of communication for a transmitter that provides multicast data to every registered member in the transmitter’s group, and it can be classified into the traditional and the reliable communication methods in general. The traditional communication method is very fast in connection but quality of service is poor. In contrast, the reliable communication method provides good quality in service but its speed is somewhat poor. Thus to enhance such demerits, this paper proposes communication method of multicast by using QCBT (Quality of Service Core Based Tree ) method. In this paper, a fair and practical bandwidth is used for data packet transmission along with the use of QCBT. The bandwidth and data processing capability filters out the transmitted data from an QCBT router through transmission packet and upgrades multimedia data packet more effectively. Therefore, recipients in various levels receive the effective data packet and based on these facts, the study actualizes and evaluates efficiency of a router, which is able to transmit the fair bandwidth from QCBT router in a simulation.
