Abstract [en]
Avionics networks are probably the best understood communication technologies when it comes to guaranteed quality of service since they need to deliver their service under all operational conditions, sometimes even in presence of failures. However, this is only possible because the right tools are available for the rather complex tasks of network configuration and traffic analysis. In the last decade, Ethernet has become a major player aboard in form of Avionics Full-Duplex Switched Ethernet. Hand-in-hand with the network development itself powerful techniques have been invented for its analysis, e.g., the network calculus. Similarly, time-triggered buses, like TTP, are more and more used on aircrafts. The challenge in network configuration of time-triggered systems is the scheduling problem and, therefore, several search-based techniques have been developed as solutions. More recently, converged networks like TTEthernet, currently used in space applications, are also becoming available for avionics use. Here, unsynchronized communication can co-exist with time-triggered synchronized communication. However, converged networks couple the challenges of traffic analysis and schedule generation and, thus, require an integrated toolset. Only the right tools will lead converged networks to be successful in industry. In this paper we, therefore, review well-established techniques in network configuration, e.g., network calculus and scheduling techniques for time-triggered networks. We then focus on current trends and solutions for integrated toolsets to configure converged networks that support concurrent synchronized and unsynchronized data transmissions.
