Bus System Structure

There are 3 possible arrangements for bus system structure in BMW vehicles. They are:

• Linear (or Tree Structure)
• Ring
• Star

The linear bus structure is the most common arrangement. Up until the introduction of the E65, the linear structure was used exclusively. The 2 other bus structures are currently used for fiber optic networks. The ring structure is used on the MOST-Bus and the star structure is used on the byteflight  system.
