	att_abstract={{We present CPM, a unified approach that exploits server multicast, assisted by peer downloads, to provide efficient video-on-demand (VoD) in a service provider environment. We describe our architecture and show how CPM is designed to dynamically adapt to a wide range of situations including highly different peer-upload bandwidths, content popularity, user request arrival patterns (including flash-crowds), video library size, and subscriber population. We demonstrate the effectiveness of CPM using simulations (based on the an actual implementation codebase) across the range of situations described above and show that CPM does significantly better than traditional unicast, different  forms of multicast, as well as peer-to-peer schemes. Along with synthetic  parameters, we augment our experiments using data from a deployed VoD  service to evaluate the performance of CPM. Original document was a presentation. This is a paper we have written, and  submitted to a conference. The first author has also been changed. }},
