Object migration in non-monolithic distributed applications

Ciupke, O.; Kottmann, Dietmar; Walter, Hans-Dirk

Abstract:

Object migration is usually applied to optimize distributed
monolithic systems. In this paper, the authors investigate whether
object migration can also be utilized in cooperative systems which
consist of autonomous components.

We show that object migration policies will not always optimize
system performance. Rather they can reduce it drastically if
different components apply these policies concurrently.

Conventional run-time support for linguistic primitives which are
usually used to express migration policies is adapted to cooperative
systems. We show that two novel approaches, place-policy and
reduction of attachment-transitiveness, can counter the degradation
caused by conflicting policies. In order to restrict
attachment-transitiveness we introduce dynamic relationships called
\emph{alliances} between objects which explicitly define cooperation
contexts.

The effects of these modifications are evaluated by simulation.
