Abstract
This paper describes the design and implementation of the Mobile Objects
and Agents (MOA) project at the Open Group Research Institute. MOA was
designed to support migration, communication and control of agents. It was
implemented on top of the Java Virtual Machine, without any modifications
to it. The initial project goals were to support communication across
agent migration, as a means for collaborative work; and to provide
extensive resource control, as a basic support for countering denial of
service attacks. In the course of the project we added two further goals:
compliance with the Java Beans component model which provides for
additional configurability and customization of agent system and agent
applications; and interoperability which allows cooperation with other
agent systems.
This paper analyzes the architecture of MOA, in particular the support
for mobility, naming and locating, communication, and resource management.
Object and component models of MOA are discussed and some implementation
details described. We summarize the lessons learned while developing and
implementing MOA and compare it to related work.
