Achievable Catalog Size in Peer-to-Peer Video-on-Demand Systems
Abstract : We analyze a system where $n$ set-top boxes with same upload and storage capacities collaborate to serve $r$ videos simultaneously (a typical value is $r=n$). We give upper and lower bounds on the catalog size of the system, i.e. the maximal number of distinct videos that can be stored in such a system so that any demand of at most $r$ videos can be served. Besides $r/n$, the catalog size is constrained by the storage capacity, the upload capacity, and the maximum number of simultaneous connections a box can open. We show that the achievable catalog size drastically increases when the upload capacity of the boxes becomes strictly greater than the playback rate of videos.
