In this paper, in order to improve scalability of conferencing system in SIP(session initiation protocol) environment, a distributed large-scale conferencing system architecture with dynamic server allocation has been proposed. For this architecture, a new extended conference information data format has been presented to distribute system load dynamically to multiple conference servers. In order to control system load and conference object, the proposed extended conference information data format has been designed to include new added elements and attributes. The extended conference event package has been used to synchronize overall system conference information data between conference servers. This paper also shows detailed exchange procedures of SIP messages between conference servers and participants for distributing system load dynamically. An extensive experimental measurements have been done to verify the performance of the proposed distributed conferencing system architecture. The results show that the proposed architecture improves highly scalability and flexibility of the conferencing system
