Das Chemnitzer StudentenNetz (CSN) setzt seit mehreren Jahren ein System zur automatischen Regelung der Bandbreite ("DynShaper") basierend auf den Grundlagen der Diplomarbeit von Jan Horbach "Dynamische Bandbreitenbeschränkung mit QoS" ein. Aufgrund der weiterhin bestehenden Notwendigkeit zum Einsatz dieses Systems, ist es nötig die DynShaper-Software zu überarbeiten, um ihre Implementierung an die Standards des CSN anzupassen und die unvollständige Dokumentation zu ergänzen. Hauptaugenmerk liegt dabei auf der Integration des Systems in die bestehende Softwarearchitektur des CSN und der Schaffung einer modularen Implementierung zur Evaluierung anderer Berechnungsverfahren.

Quality of service is commonly used to shape network traffic to meet specified criteria. The various scenarios include limiting and reserving bandwidth for a particular application, host or user, prioritizing latency sensitive traffic or equal distribution of unreserved bandwidth. The DynShaper software distributes and controls a traffic quota by more sophisticated means than fixed per user limits and simple disconnection after the user reaches the limit. It distributes the quota on a daily basis, where each day receives the same share. The users are sorted into predefined groups with different bandwidths depending on their recent consumption. This classification is periodically updated to ensure the sorting order is maintained. The bandwidths of these groups is dynamically adjusted depending on the actual consumption to provide an efficient utilization. This thesis presents another distribution model using a case-based reasoning approach, a method for machine learning which is classified as conventional artificial intelligence. Case-based reasoning tries to solve new problems based on the solutions of similar problems from the past. Controlling the network traffic to remain within a fixed quota can be modeled as such a problem if the traffic patterns are recurring. Possible solutions can be derived from statistical data and altered to suit the new problems. When an untested solution is applied, the software supervises the execution and revises the solution accordingly, if the actual results deviate from the precalculated schedule.
