The choice between a P2P and a conventional centralized realization of VoD service on cable television network can be made after a comparison of the traffic in different sections of the network. Until recently, the centralized architecture has been the most popular architecture for providing VoD service to subscribers of cable television network. With the growth of the network, however, this type of architecture has become inapplicable because of the need for a large number of outgoing video streams from the central VoD server, i.e. high bit rate through the central transmission network. This paper is to compare the necessary bit rates on different network sections of P2P and centralized VoD architecture and to study the influence of the more important parameters on these bit rates.
