Transient Analysis of an Overlay Multicast Protocol

This paper presents the transient performance study on the adaptability of an application layer multicast protocol, namely adaptive overlay multicast (AOM). The study focuses on how the application layer multicast tree structure adapts to network dynamics and faults by using efficient tree management and adaptation algorithms, thus reducing the adverse effects of network faults on the application performance. We present extensive simulation studies as well as studies using real Internet data The results show that AOM is highly adaptive to network dynamics while incurring low overhead.
