Demonstrating the feasibility of media management in ReCANcentrate

Abstract

Star topologies are rising the interest of newer fieldbus communication technologies like TTP/C and FlexRay, given the dependability advantages stars can offer. However, it is also possible to take advantage of a mature technology such as Controller Area Network [1] (CAN), while benefiting from stars. For that, we developed a CAN-compliant replicated star called ReCANcentrate. It includes two hubs that are coupled with each other, thereby forcing a single broadcast domain that allowed us to define, in a previous work, a strategy for each node to easily manage the replicated star. To demonstrate the feasibility of this management, this paper presents its on-going implementation as a driver to be executed at each node. ©2009 IEEE.
