Abstract
Clans are introduced as a basic concept of an operating system kernel. They permit full algorithmic control of process interaction in a user definable but secure way. All communication across a clan’s borderline is inspected and possibly modified by the clan’s so called chief task. Thus the mechanism can be used for protection, remote communication, debugging, event tracing, emulation, connecting heterogeneous systems and even process migration. It has been implemented in the operating system L3 where, besides some smaller applications, remote message handling and a multi-level-security monitor rely on clans.
