Comparison of system level networking solutions with high-speed CAN networks
Heikki Saha, Sandvik Tamrock Oy · 2003
There are different solutions to build CAN-networks and every solution has it's own benefits and drawbacks. The packet structure of CAN frames causes most of the limitations, when compared i.e. with Ethernet. Especially with high bit rates, up to 1 Mb/s, those limitations force to very careful network design. This paper will present, that in all selections of networking solutions must be done by taking into account the requirements of the application. Bus, star and tree topologies are examined with active and passive HUBs, repeaters and switches and many pitfalls are found and analyzed. In high speed CAN-networks, inter-segment routing has been found to be one of the most reliable implementation in complex systems.
