Background Analysis and Design of ABOS, an Agent-Based Operating System

Modern operating systems need to be extensible and versatile. What this means is that the operating system should certainly accept new behaviour and alter present behaviour without too much difficulties and that it should preferably have the ability to get this done with no, or minimal, outage. At the same time, over the past years the relevance of the network has grown substantially, resulting in a requirement for operating systems to operate in a distributed environment. To accomplish this flexibility and distributedness, I’ve created and examined ABOS, an Agent-Based Operating System. ABOS uses agents to fix all the duties of the operating system kernel, therefore moving away from traditional monolithic kernel structures. Premature results indicate that I have gained in flexibility and modularity, developing a fault-tolerant distributed operating system that can fine-tune and be adapted to just about any situation with minimal loss of performance. Within ABOS a few tasks have been designed further, and there exists a demo of how the agent-based filesystem may work.
