The Time-Triggered Architecture (TTA) is a distributed computer architecture for high-dependable real-time systems. The core building block of the TTA is the communications protocol TTP/C.
This protocol is designed to provide non-faulty nodes with consistent data despite faulty nodes. To achieve this the protocol assumes that a fault is either a reception fault or a consistent send fault of some node. Although the communications protocol of the TTA uses this rather optimistic failure mode assumption, the TTA can isolate and tolerate a broader class of faults. This is possible by making intensive use of the static knowledge present in a TTA distributed computer system. This off-line available knowledge allows to build interconnection networks, which transform failure modes of nodes into those the communications protocol can deal with. This paper will discuss three alternative implementations of interconnection networks for the TTA, which are designed to meet different failure mode assumptions.
