| Abstract(in English) | Skype is a Peer-to-Peer (P2P) based Internet telephony service. In the Skype network, super nodes are chosen from among all ordinary end-user nodes and handle particular tasks such as the management of user information, call establishment, and traffic relay for Network Address Translation (NAT) traversal. The significant characteristic of the Skype network is a load-balancing feature such that the load shared by super nodes is dynamically distributed according to the number of super nodes. In this paper, we analyze the performance of this type of P2P-based dynamic load distribution systems. In our analytical model, new nodes joining the network form a nonstationary Poisson process, and the number of online nodes is approximately analyzed with an M(t)/M/∞ queue. Numerical examples show that the P2P-based dynamic load distribution system keeps the load of super nodes low, providing real-time communication services under the environment in which the number of user nodes dynamically changes. |
