Abstract

Content delivery networks (CDNs) are so far efficient tools to distribute a fast growing amount of information to the users. To ensure the required Quality of Service (QoS), more and more distributed and even hybrid P2P system architectures are used to cope with the not sufficient bandwidth and capacities of a single server. The proposed algorithm solves the problem to find an optimal position for the server or service nodes in a hybrid P2P system depending on network parameters and especially user activities. Moreover, simulations show that the customer peer assignment to the service nodes results in an almost equal partition of the network. Furthermore, an automatically movement of the service node can be induced in case of significant load changes.
