CHORUS is a distributed system based on a small set of powerful concepts: actors, messages, and ports. A complete operating system has been implemented on a local network of multiprocessors and is now available. The CHORUS architecture is well adapted to the implementation of distributed fault-tolerance mechanisms. This paper presents our results in this field, the ''Coupled Actors,'' mechanism and the ''Activity Message'' concept and outlines two other projects, recently launched in the same domain, building upon the CHORUS system.
