A Multicast-On-Large-Demand Approach to the Flash Crowd Problem

In this paper we propose a multicast-on-large-demand (MOLD) approach to the flash crowd problem. A MOLD Web server may dynamically open a multicast channel for resources when detecting a very high demand for them, and it reverts back to the normal unicast mode when the flash crowd subsides. A number of mechanisms necessary for realizing the MOLD system are thoroughly discussed. We have implemented the MOLD system in Java and evaluated the performance in a test-bed.
