Functionality and Performance Issues in an Agent–Based Software Deployment Framework

Deploying and maintaining software in a distributed system includes software delivery, remote installation, starting, stoping, and modifying in order to configure or re-configure a system according to user needs. This paper deals with an agent-based framework where intelligent and mobile agents provide the means to implement a distributed system and enable its evolution by taking partial or full responsibility for software deployment tasks. Agents are organised into agent teams, where one agent is the team leader responsible for planning, while the others are operational agents capable of executing a defined plan. The formal model, as well as functionality and performance issues, are elaborated. Special attention is paid to deployment strategies and their optimization, while taking into account characteristics of distributed system nodes and the network connecting them. Simulation-based evaluation of agent serialization, migration and deserialization parameters, and their influence on overall performance, is included.
