Abstract

NGN (Next Generation Network) is one of IP-based network that integrates different communication technologies interfacing with each other such as PSTN, ATM, Frame Relay, ADSL, WLAN and so on. In addition, Multicast support in NGN is essential to some specific applications for file transmission in large capacity, video broadcasting and streaming, video conference, and on-line game. To support these multicast applications, some critical problems, such as delay and packet loss in multicast communications among users on different network must be solved. This study proposes a structure to eliminate above problems and it is based on the extension of multicast router functions for efficient, optimum and reliable multicast support in NGN. In other words, our architecture solves the delay problem and dramatically cuts down implosion of feedback information concentrated on senders. Therefore, our approach could be a basic multicasting mechanism to support seamless and reliable mobile multicast in NGN environment.
