Application-Level Hierarchical Agreement. With TTEthernet providing an asymmetric benign fault model communication network, clients of this network are guaranteed to receive good data or no data. What remains to be resolved is whether all good replicants in a set got the data or not. Using hierarchical Byzantine agreement as described above, applications on a TTEthernet can resolve this question efficiently by sending only a minimum size frame. However, this only works if all the components, including the end systems, enforce a benign fault model. The status returned from any end system that does not enforce a benign fault model cannot be trusted. For these simplex nodes, a full data exchange is required.
