QoS-Aware Ring Redundancy Protocol (QoS-ARRP) for High-Availability Ethernet Networks
Résumé
During the last decade, Ethernet’s significance has
increased in many embedded systems application areas, such as
automotive, avionics and automation. However, guaranteeing the
required availability level for such applications on Ethernet is
still a hot research topic. In this specific area, we propose in this
paper a new redundancy protocol for high availability Ethernet
networks, called QoS-Aware Ring Redundancy Protocol (QoSARRP).
First, the specifications of such a protocol are detailed,
including the frame redundancy and filtering management, the
auto-configuration mechanisms, as well as the maximum recovery
time analysis. Second, the numerical results of the recovery time
have shown the impact of the protocol parameters to tune and
the trade-off between availability and scalability of the network.
Moreover, we have benchmarked the state-of-the-art results on
the recovery time against ours. A noticeable enhancement of
the maximum recovery time with our proposal, thus of the
availability level, has been highlighted.
