“…In Phase-3, even better performance than the TTEthernet can be obtained. The worse performance of TTEthernet is due to the Timely Blocking problem that leads to the bandwidth inefficiency caused by empty intervals introduced by the switches to guarantee hard delay [20][21][22]. For instance, BAF of 1.91 Mbps and 3.50 Mbps are obtained in the OBC1-SW1 link for FTTE (Store and Forward) and TTEthernet solutions respectively.…”

The success of small satellites has lead to the study of new technologies for the realization of Nano and Micro Launch Vehicle (NMLV) in order to make competitive launch costs. The paper has the objective to define and experimentally investigate the performance of a communication system for NMLV interconnecting the End Systems as On-Board Computer (OBC), telemetry apparatus, Navigation Unit...we propose a low cost Ethernet-based solution able to provide the devices with high interconnection bandwidth. To guarantee hard delays to the Guide, Navigation and Control applications we propose some architectural changes of the traditional Ethernet network with the introduction of a layer implemented in the End Systems and allow for the lack of any contention on the network links. We show how the proposed solution has comparable performance to the one of TTEthernet standard that is a very expensive solution. An experimental test-bed equipped with Ethernet switches and Hercules boards by Texas Instruments is also provided to prove the feasibility of the proposed solution.
