Abstract:
Object migration is an often overlooked topic in distributed object-oriented platforms. Most common solutions
provide data serialization and code mobility across several hosts. But existing mechanisms fall short in
ensuring consistency when migrating objects, or agents, involved in coordinated interactions with each other,
possibly governed by a multi-phase protocol. We propose an object migration scheme addressing this issue,
implemented on top of the Coordination Language Facility (CLF). It exploits the particular combination of
features in CLF: the resource-based programming paradigm and the communication protocol integrating a
negotiation and a transaction phase. We illustrate through examples how our migration mechanism goes
beyond classical solutions. It can be fine-tuned to consider different requirements and settings, and thus be
adapted to a variety of situations.
