The current generation of P2P networks is intended to provide cost-effective alternatives to the traditional clientserver architecture. The main goal is to store and retrieve data in a decentralized manner. The challenge in doing so consists in creating a stable overlay network that allows for fast and efficient searches. In this paper we consider the Chord P2P algorithm in this context and analyze its stability and efficiency with stochastic methods. We present realistic probabilities for a disconnection and investigate the corresponding scalability.

Abstract. The G-Lab project aims to investigate concepts and technologies for future networks in a practical manner. Thus G-Lab consists of two major fields of activities: research studies of future network components and the design and setup of experimental facilities. Both is controlled by the same community to ensure, that the experimental facility fits to the demand of researchers. Researchers gain access to virtualized resources or may gain exclusive access to resource if necessary. We present the current setup of the experimental facility, describing the available hardware, management of the platform, the utilization of the Planet-Lab software and the user management.
