Previous Research

• Software Architecture Modeling into an MDA framework:– An approach for the Software Architecture Modeling

into a MDA framework– Software Architecture in both levels:

• Platform Independent• Platform Specific

• A UML profile for Service Oriented Architectures:– An application of the previous approach for SOA

Objetives

• The goal of this task is to produce an abstract architecture and computation model for large scale open MAS populated with software agents with agreement capabilities:

– It helps structuring the MAS models, and the MAS development process in general

– It will provide high-level guideline for software integration into the AT MAS platform in task 7.2.

WorkPlan Year 1

• Detailed analysis of existing architectural models for open MAS (M3)

• Definition of requirements for an organisation-based MAS platform. (M6)

• Definition of the AT MAS platform abstract architecture. (M12 1st version)

• Deliverables:– D7.1.1 Abstract architecture requirements. (M6).– D7.1.2 Abstract architecture design. (M12). Yearly revisions.

Task 7.2. Multiagent System Platform

A. Espinosaaespinos@dsic.upv.es

Objective

• To develop a new platform that allows for the management of multiagent open systems

– Performance and scalability

– Security

– Support for organizational structures

– “Very close” to the operating system

– A previous experience to develop a new multi-agent based operating system (Task 7.3)

www.agreement-technologies.org

Current status

• A FIPA-like platform implemented on top of the Linux OS is available

– Agents as an extension of the Linux process concept

– High performance P2P communication channel between agents and platforms services

– Very scalable with regard to the number of agents and hosts

– Basic application program interface: agent management and message communication

– C and C++ as the programming languages

Work in progress

• Kerberos based security for authentication and confidentiality

• Agent units and transparent agent-unit communication

• Protocol-based communication API

• Event tracing service

• Platform management and monitoring tools

• Agent communication languages and content languages

• Lightweight agents to support any programming language and any operating system

Work plan

• Years 1 and 2

– To develop platform versions based on the results of the current work in progress, in order provide to the rest of the members a serious alternative to the current platforms

– To learn a lot about multi-agent systems from the works of the other tasks, in order to define the work plan for years 3 to 5

Task 7.3: Multiagent System-Based Operating Systems

Motivation

• To start a new research line with the long-term goal:

– to use the concept of agreement among agents as the key to develop a new operating system from scratch.

• In order to support current and future applications, the the operating system has to offer specialized services to applications and users

• The introduction of agent technologies to operating systems – will facilitate their extension to cope with future requirements, as

long as enhancing their flexibility and scalability.

www.agreement-technologies.org

Activities

• Definition of new abstractions – new concepts such as agent, organization, norm and interaction will be

defined form the viewpoint of the operating system.• Operating system design

– the preliminary design of a new operating system based on the concept of agent will be carried out. The classic issues in the design of operating systems, such as processor scheduling, memory management, system resources, communication, protection, security and user interface, will be extended to accommodate the new abstractions

• Operating system prototype– By using the proposed design, this activity will identify the main

components of the new operating system in order to develop a prototype for a particular hardware platform.

• Deliverables.– D7.3.1 Agent-based operating system specification. Months 18, 24,36.– D7.3.2 Agent-based operating system design. Months 24, 36, 48– D7.3.3 Agent-based operating system prototype. Months 48, 60
