The new structure of an operating system

Yasuhiko Yokote

Mario Tokoro

Abstract: This paper proposes the new structure for an operating system in an open and mobile computing enviromnent. The structure is characterized by object/metaobject separation, metahieraxchy, and object migration. We then present the practical implementation of the Apertos operating syste~n based on the proposed structure, where reflectors are introduced for metaobject programming and MetaCore for providing the common primitives. We also present some measurement results of the Apertos operating system.

Migration is one example of the insufficiently used potentials of distributed systems. Although migration can enhance the efficiency and the reliability of distributed systems, it is still rarely used. Two limitations contained in nearly all existing migration implementations prevent a widespread usage: migration is restricted to processes and the migration mechanism, i.e. the way state is transferred, is not adaptable to changing requirements.In our approach, migration is an operation provided by every object of any type. Triggered by higher level migration policies, the object migrates itself using an object-specific migration mechanism. Changing requirements are handled by higher level migration policies that adapt migration by exchanging the object's mechanisms.Adaptable migration was implemented within the BirliX operating system. Different migration mechanisms are accomplished by different meta objects, which can be attached to other objects. If an object has to be migrated, the meta object does the migration. Changing environmental requirements are handled by exchanging the meta object. As a result, each object has its own migration mechanism. The approach has been examined by implementing a couple of well-known migration mechanisms via meta objects. This paper describes the meta object implementation of the Charlotte migration mechanism.
