QRP05-6: Combined Adaptive Congestion Control Method for Communication-Broadcasting Integrated Services

This paper proposes a combined adaptive congestion control method for massive and intensive telecommunication traffic expected in communication-broadcasting integrated services. The proposed method adaptively controls data transmissions from viewers by combining transmission restriction and delayed transmission depending on the congestion states, so that the severe congestion can be avoided effectively. Furthermore, it utilizes the broadcasting channel which is not only reliable, but also scalable for controlling the responses from vast numbers of viewers. The performance of the proposed method is evaluated through experiments on a test bed where approximately one million viewers are emulated. The obtained results quantitatively demonstrate the performance of the adaptive control method and its effectiveness under massive and intensive traffic conditions.
