Abstract (EN)

This paper presents a method to design reliable applications composed of communicating entities. This method is based on the separation of communicating and processing functions to create a software “network” independent of the computational processes. Common functionalities are isolated to reduce the overhead of replication based approach. In contrast to classical techniques only the processing part of entities is replicated. We exhibit a homogeneous communication structure: the R- CHAIN. We describe an algorithm to dynamically reconfigurate the R-CHAIN in presence of host failure. This algorithm provides an efficient way to maintain end-to-end communication.
