Abstract—In recent years, videoconferencing technology has become a very important topic in modern business and education. Videoconferencing allows remote teams to collaborate, despite being different time zones. Multimedia content with different rate streams can be generated from multiple users during a video conference. This paper presents an analytical study for rate allocation in a collaborative multi-source multicast framework for unbalanced (different) rate streams. This rate allocation study attempts to maximize the overall throughput for joint rate allocation for different rate streams. The analyzed framework has been deployed on a Peer-to-Peer (P2P) network. The framework tries to exploit the different benefits introduced by this type of network. Our analysis allows us to know about limitations and challenges when this type of scenario occurs.


Keywords—content distribution, peer-to-peer networks, multicast, multi-source
