Abstract

In order to support efficiently the multimedia applications, such as virtual classroom, video conferencing and tele-medical, the efficient multipoint-to-multipoint(MP-to-MP) connection management function is essential. Shared tree is reported as the most useful method for this purpose. In this paper we propose a new MP-to-MP connection setup & management scheme, called CIMA(Cell Interleaved Multiplexing on ATM) scheme,which is a VC merging method for MP-to-MP communication using shared tree. In the CIMA scheme,MRM cell delivers the cell merging information to the next node. The receiving node can identfy cells which arrived through a channel using the same VPI/VCI by the merging information in the MRM cell. Therefore the CIMA scheme can solve easily the Cell Interleaving Problem(CIP) that happens in VC merging. We analyzed the overhead of the proposed CIMA by mathematical analysis,and simulated the buffer usage of CIMA with OPNET. As the result of analysis,we found that the CIMA scheme has acceptable merging overhead and doesn't cause the buffer scare problem.

원격 회의, 원격 교육, 원격 진료 등의 서비스를 제공하기 위해서는 하부 통신망에서 multipoint-to-multipoint(MP-to-MP) 연결을 효과적으로 제공해야만 한다. 최근의 연구결과들에 의하면 MP-to-MP 연결 설정 및 관리를 위하여 shared tree를 사용하는 것이 효과적인 것으로 분석되고 있다. 본 논문에서는 ATM망에서 MP-to-MP 통신 구현 시 필요한 shared tree 기반의 VC 다중화 방안으로서 CIMA(Cell Insterleaved Multiplexing on ATM) 기법을 제안한다. CIMA 방식에서는 다중화가 발생하는 경우 MRM(Multicast RM) cell을 이용하여 다중화 정보를 다음 노드로 전달한다. 수신자는 MRM cell에 담긴 다중화 정보를 이용하여 동일한 VPI/VCI를 사용하는 채널로 들어온 cell들의 송신측을 구분할 수 있으므로 VC 다중화에서 발생하는 CIP(Cell Interleaving Problem)를 해결할 수 있다.
