Open and reliable group communication processing: the FITOS-RPC approach

The paper describes the design of a fault tolerant group remote procedure call system based on the ISO RPC international standard ISO/IEC 11578. The system extends the original model providing detection and handling of orphan computations caused by process crashes or network partitioning. A group communication protocol supports replicated procedure execution preserving total message ordering among nodes. An X.500 directory service is also used to provide transparent service location.
