The subject of this thesis is the development of a lab environment that allows a dynamic and automated configuration of lab networks for forthcoming experiments. Such lab experiments are of special importance in network research. In large labs, the efficient use of resources and the real-time conduction of experiments is a difficult task. The fast switch between certain scenarios and special configurations is challenging the configuration task. Therefore, the goal is to develop a dynamically reconfigurable lab network. SNMP (Simple Network Management Protocol) has become a de-facto standard for network management. In this work, SNMP was used to test and to configure the components of a lab prototype. The main task was to administrate virtual LANs (VLANs) by (re-)configuring an ethernet switch. With the help of this technology, logically separated local networks can be mapped to the same physical infrastructure. A software package was written, which dynamically constructs new experimental setups based on predefined rules. The configuration is done by SNMP and SSH scripts. The desired scenario can be defined using a simple XML file. The implemented software package mainly consists of two tools: the LabManager and the LabViewer. The LabManager does the configuration of the lab network while the LabViewer represents the experimental setup visually on a webpage. Finally, a lab network was set up on which several experiments were conducted. The implementation was verified and improved by ongoing applications and experiments in this lab network.
