12.9 Distributed Systems
12.9.1 Introduction
SCIOPTA is a message based real-time operating system and therefore very well adapted for designing distributed
multi-CPU systems. Message based operating systems where initially designed to fulfil the requirements of dis-
tributed systems.
12.9.2 CONNECTORS
CONNECTORS are specific SCIOPTA processes and responsible for linking a number of SCIOPTA Systems.
There may be more than one CONNECTOR process in a system or module. CONNECTOR processes can be seen
globally inside a SCIOPTA system by other processes. The name of a CONNECTOR process must be identical to
the name of the remote target system.

A connector process can be defined as default connector process. There can be only one default connector process
in a system and it can have any name.
