A better dynamic broadcasting protocol for video-on-demand

Dynamic broadcasting protocols for video-on-demand combine features of reactive and proactive distribution protocols to offer good performance over a wide range of request arrival rates. We present a new dynamic broadcasting protocol based upon the fast broadcasting and the new pagoda broadcasting protocols. At low to medium arrival rates, our dynamic fast-pagoda broadcasting protocol performs as well as the best reactive protocols. Its bandwidth requirements at high arrival rates are within ten percent of those of the best static broadcasting protocols.
