Abstract :
In this paper, we study the impact of churn on object management policies deployed in a CDN-P2P system. The effectiveness of buffer enlargement and replicating control, in reducing the effects of churn on these policies, is analyzed. We have found that neither the simply enlargement of peers´ storage capacity nor a zero replicating strategy are effective actions to improve performance of an object management policy. Policies that implements different caching strategies are evaluated, and a YouTube video collection, which records over 1.6 million video´s log, is used in our experimental studies.
