Abstract

In this paper, we investigate a novel Multipoint Video Conferencing (MVC) architecture potentially suitable for Peer-to-Peer (P2P) platform, such as Gnutella. In particular, we present an election protocol (extension to Gnutella) where the Multipoint Control Unit (MCU) of the MVC is dynamically migrated among peers when new peer joins or leaves. Simulation result shows that this improves overall conferencing performance compared to the system with static MCU by minimizing total traffic, individual node hotness, and video composition delay.

点对点网络视频会议的动态MCU布局
在本文中,我们研究了一种可能适用于点对点(P2P)平台(如Gnutella)的新型多点视频会议(MVC)架构。特别地,我们提出了一种选举协议(扩展到Gnutella),其中MVC的多点控制单元(MCU)在新的对等体加入或离开时在对等体之间动态迁移。仿真结果表明,与静态MCU系统相比,该系统通过最小化总流量、单个节点热度和视频合成延迟,提高了整体会议性能。
