Chair for Network Architectures and Services

Due to technological advances, network architectures must handle a growing amount of exchanged data and number of connections. This results in increasingly complex systems. In the domain of industrial systems, it is necessary to provide performance guarantees for large networks. This includes bounded end-to-end latency, bounded end-to-end jitter, and maximum buffer usage. This paper presents the analytic approach of Network Cal-culus by providing a basic theoretical background and ap-plying it to simple systems. Finally it is shown how Network Calculus can be applied to Ethernet and AFDX (Avionic
