The TTA Network - A Safe Yet Flexible Communication Architecture for Vehicle Electronics
Georg Stöger · SAE technical papers on CD-ROM/SAE technical paper series · 2001
The paper presents a communication architecture for distributed embedded computer systems that require to transmit safety-critical real-time data - which must not be delayed - on the same bus as non-critical data. Such non-critical data can come from sources like sensors and event-based traffic, typically for on-demand diagnosis. This architecture utilizes the communication protocols TTP/C and TTP/A, and a software layer in the distributed nodes, to provide a fault-tolerant platform for reliable yet flexible communication over a multiplex bus.
