iTVP is a system built for IP-based delivery of live TV programming, video-on-demand and audio-on-demand with interactive access over IP networks. It has a country-wide range and is designed to provide service to a high number of concurrent users. iTVP prototype contains the backbone of a two-level hierarchical system designed for distribution of multimedia content from a content provider to end users. In this paper we present experience gained during a few months of the prototype operation. We analyze efficiency of iTVP content distribution system and resource usage at various levels of the hierarchy. We also characterize content access patterns and their influence on system performance, as well as quality experienced by users and user behavior. In our investigation, scalability is one of the most important aspects of the system performance evaluation. Although the range of the prototype operation is limited, as far as the number of users and the content repository is concerned, we believe that data collected from such a large scale operational system provides a valuable insight into efficiency of a CDN-type of solution to large scale streaming services. We find that the systems exhibits good performance and low resource usage.
