A COMPARISON OF TWO DIFFERENT JAVA TECHNOLOGIES TO IMPLEMENT A MOBILE AGENT SYSTEM

摘要

This paper describes an evaluation of the two technologies Agletsrnfrom IBM Japan and JavaSpaces from Sun Microsystems used tornimplement the same mobile agent system. The Aglets frameworkrnwas initially designed to support mobile agents, while the JavaSpacesrnframework was not. In this evaluation we have looked at issues likernadaptability, configurability, extensibility, location transparency, andrnabstraction level. We have also measured the effort that was used (inrnhours) and the lines of code necessary to implement the same mobilernagent system using the two different technologies. We found thatrnthere are several advantages by using JavaSpaces instead of Agletsrnfor implementing mobile agent systems even if it was not intentionallyrndesigned to support this. Our evaluation does not look at therndifference in performance of the two technologies.
