Abstract

As the automotive industry adopts Ethernet for in-vehicle network technology, automotive Ethernet has to handle bounded delay traffic. IEEE std 802.1Q introduces the stream reservation protocol (SRP) to reserve resources for time-sensitive traffics. SRP uses bridge-by-bridge propagation for its messages and registers VLAN ID and group address before making Audio-Video (AV) stream reservations. In this study, we propose a simplified SRP scheme over the Software-defined Network (SDN) for in-vehicle bridged networks. The proposed scheme exploits the topology and bridge information of bridged networks. A centralized stream reservation procedure in the scheme replaces the bridge-by-bridge propagation for SRP reservations. The reservation procedure does not require VLAN ID and group address registration. We implemented a prototype of the proposed scheme and showed that reserved flows are well protected when links of bridges are overloaded.
