On Ttethernet for Integrated Fault-Tolerant Spacecraft Networks
On TTEthernet for Integrated Fault-Tolerant Spacecraft Networks Andrew Loveless∗ NASA Johnson Space Center, Houston, TX, 77058 There has recently been a push for adopting integrated modular avionics (IMA) princi- ples in designing spacecraft architectures. This consolidation of multiple vehicle functions to shared computing platforms can significantly reduce spacecraft cost, weight, and de- sign complexity. Ethernet technology is attractive for inclusion in more integrated avionic systems due to its high speed, flexibility, and the availability of inexpensive commercial off-the-shelf (COTS) components. Furthermore, Ethernet can be augmented with a variety of quality of service (QoS) enhancements that enable its use for transmitting critical data. TTEthernet introduces a decentralized clock synchronization paradigm enabling the use of time-triggered Ethernet messaging appropriate for hard real-time applications. TTEther- net can also provide two forms of event-driven communication, therefore accommodating the full spectrum of traffic criticality levels required in IMA architectures. This paper explores the application of TTEthernet technology to future IMA spacecraft architectures as part of the Avionics and Software (A&S) project chartered by NASA's Advanced Ex- ploration Systems (AES) program.

Software-Defined Networking for Real-Time Ethernet
Presented at the 13th International Conference on Informatics in Control, Automation and Robotics (ICINCO), July 2016, http://www.icinco.org/ Software-defined Networking for Real-time Ethernet Jia Lei Du and Matthias Herlich Salzburg Research, Jakob Haringer Straße 5/3, Salzburg, Austria {jia.du, matthias.herlich}@salzburgresearch.at Keywords: Software-defined Networking, Real-time Ethernet Abstract: Real-time Ethernet is used in many industrial and embedded systems, but has so far mostly been statically configured. However, in the future these network configurations will be required to change dynamically, for example for highly flexible production lines or even software upgrades in modern cars that add new features which require changes to the in-vehicle network. Software-defined networking (SDN) is already increasingly used to dynamically configure non-real-time networks. In this paper we explore the idea of a software-defined real-time Ethernet. We analyze the features of current real-time Ethernet protocols, the applicability of SDN and give an overview of potential advantages of software-defined networking for real- time communication which can enable features not achievable using current solutions. In the future this development will likely lead to more flexible, efficient and robust real-time networks. 1 INTRODUCTION centralized intelligent controller with “dumb” forwarding devices in the data plane of the network Real-time Ethernet (RTE) allows the use of cost (McKeown et al., 2008). By monitoring network- effective, widespread and high-bandwidth Ethernet wide state, the controller obtains an up-to-date view technology in industrial environments like of the network and can dynamically adapt flows as automation, process control and transportation necessary. -
