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.

The development of the Internet during the last years has shown that it becomes harder to integrate new functionality in order to fulfill the demands of new applications and the capabilities of new transport technologies. Especially the core mechanisms (TCP/IP) are hard to change. Thus the development of a new Internet architecture has been discussed for some time now. In this work we present a service-oriented approach for a new network architecture. At first it is argued which kinds of flexibility should be provided by an architecture. Then it will be shown which common principles of service-orientation support this flexibility. Further we present technical considerations for implementing network functionality by services.
