Performance Analysis of Ethernet Power link Applied to Ethernet of In-Vehicle Network
Recently, LIN, CAN, and Flex Ray have most often been used in In-Vehicle Networks (IVNs). Automotive manufacturers are applying active safety systems, Infotainment devices, entertainment devices, etc., and those systems communicate large amounts of data. However, CAN or Flex Ray cannot handle a large amount of data with real-time performance, so applied research on Ethernet as an alternative to the existing network of IVNs is actively underway. In recent research, many manufacturers have studied Switched Full Duplex Ethernet (SFDE). However, SFDE supports few network topologies and is expensive for implementing in networks. Ethernet Power link (EPL) is presented as an alternative for SFDE field bus network protocol based on Ethernet. The protocol stack of EPL is open source, and it supports standard Ethernet chips (not ASIC). Also, EPL guarantees high real-time performance and supports various topologies. The performance of EPL is analyzed and its suitability for Ethernet in IVNs is evaluated.
