Real-time constraints, reconfigurability and safety have a direct impact on architecture design and on the validation/certification process, at the aircraft and system level. Current certification of Integrated Modular Architecture (IMA) avionics using network calculus cannot accurately predict communication and processing latency. Here is a solution for IMA-based avionics to generate certification tests, conduct what-if analysis, […]

Ethernet is widely used for all kinds of applications. However, for demanding multimedia streaming applications in a fully-loaded network, Ethernet is not the right choice due to its limited Quality-of-Service (QoS) support. IEEE 802.1 Audio/Video Bridging (AVB) standard, an extension to legacy Ethernet, provides the QoS features needed for multimedia streaming such as time synchronized […]
