    Reserving the resources for the requested applications is one of the most effective schemes that were proposed to offer the time-critical multimedia applications recently. Because the resource is limited, an ability to provide resource reservation in advance is essential in multi-party applications with dynamic accessing and leaving of user such as modern integrated (voice, video and data) collaboration system. Modified Greedy (MG) algorithm was proposed for multicast routing in advance reservation environment (time of joining in and leaving from multicast group need to be informed to source node). However, MG algorithm has an assumption that member of multicast group join in and leave from multicast session punctually. In this work, we propose the late version of MG algorithm that yields a good performance in the situation that the inaccuracy of information given by user might be happened, as shown in our simulation results.
