Distributed Session Announcement Agents for Real-Time Streaming Applications

End-users who want to receive real-time streaming data on the Internet must first obtain the session information. A session information distribution system that distributes the available session information to all potential receivers must be scalable and work with low latency. We present the design and implementation of a session information distribution system using multiple session agents. This system distributes the session information to the Internet users effectively, and can limit information distribution to specified users by labeling. We evaluated the actual implementation on the PlanetLab and OpenDHT to measure the session information distribution delay and retrieval time. The experimental results have shown that the session agent can distribute session information to the entire Internet with good scalability and end-users can retrieve the information with low latency.
