It is introduced CARRING II, a further development of the CARRING communication network. CARRING is a reliable, ring-based, real-time Local Area Network (LAN). It was developed to connect e.g. mechatronic systems in cars, but it is also applicable to general LANs. The proposed network tries to solve the known problems of LANs with bus topology, e.g. limited scalability or limited reliability. For CARRING II, the node structure, frame types, a buffer management with a special reservation mechanism and some other basic concepts are described here. Furthermore, CARRING II applies a medium access scheme that merges concepts of Time Division Multiple Access (TDMA) and Register Insertion (RI). It is scalable and cost-effective. For CARRING II, a new node setup and frame format, and a new buffer reser vation scheme together with transaction priority handling were introduced. The proposed medium access scheme is a combination of TDMA and Register Insertion that guarantees a fair and efficient bandwidth allocation.
