Architecture group

• Goals
• Development of methods and architectures
  supporting the design of distributed systems
• Proof of concept through application on real
  systems
• Some keywords
• complexity, structure, abstraction, concepts,
  design process

Architecture group

• Master Assignments are embedded in the running
  projects of the group
• MODA-TEL
• WASP
• ArCo
• Accounting

4
MODA-TEL (Model-driven architecture for
Telecommunications Systems Development and
Operation)

• MODA-TEL Project of the European Union with the
  participation of Eurescom, France Telecom, IO
  software, Intracom, Softeam, Telenor, T-Systems
  Nova and CTIT (Arch group)

5
OMG Model-driven architecture

• Motivation and objectives
• Preserve investment in distributed applications
• Integration of various middleware platforms,
  languages and application types
• Approach and techniques/technologies
• Separation of concerns (functionality versus
  implementation) through models
• Embrace available technologies (CORBA, J2EE, XML,
  Web services, etc.)

6
Models in MDA
7
MDA research issues

• UML is the only standard design language for
  working with MDA
• Yet is has some limitations concerning a.o.
• Specification of behaviours
• Formal support for refinement
• Specification of QoS issues
• Support to refinement of QoS requirements
• Etc.

8
MODATEL

• Project aims at providing methodologies and tools
  to apply MDA and related technologies for telecom
  applications
• In this project the architecture group aims at
• Evaluating the applicability and limitations of
  the MDA approach
• Providing alternative techniques to circumvent
  the limitations of UML and its underlying
  architectural model

9
Mini MODA-TEL

• Topics for Master Assignments
• Evaluation of MDA Case Tools
• ArcStyler (iO)
• Objecteering (Softeam)
• Identification of generic concepts for PIMs
• Define Common abstractions
• Mappings (Define implementation relations from
  common abstractions)

10
WASP (Web Architectures for Service Platforms)

• WASP Freeband (Dutch) project with the
  participation of the 'Telematica Instituut',
  Ericsson and CTIT (Arch group)
• Project aims at applying web services technology
  to speed-up the development and deployment of
  context-aware services in a mobile environment

11
Movie service
12
Mini WASP

• Topics for Master Assignments
• Development of an instant messaging application
  on a mobile terminal using web services for
  communication between client and server
• Development of an application to monitor the
  quality of a wireless connection and deliver
  information to the user via web service
  technology

13
Web services issues

• Research Questions
• How to control the development process when web
  services are used?
• What are the proper abstractions?
• How to specify, enforce, combine and verify
  service behaviour?

14
ArCo (Architectural Concepts for Distributed
Systems Design)

• ArCo Internal Project of the Arch group
• Project Objectives
• Development of concepts, languages, methodologies
  and tools for model-based design of distributed
  systems that support enterprise level
  requirements
• Ontology-based development of domain-specific
  languages for modelling Semantic Web-services
  applications

15
Mini ArCo

• Topics for Master Assignments
• Development of tools to support the design of
  business requirements, and distributed
  applications to establish a formal relation
  between these two types of design
• Enterprise Application Integration using Semantic
  Web Technology
• Tool support for Web Service Semantic Annotation,
  Discovery and Integration

16
Accounting

• Accounting Internal Project of the Arch group
• Provider-Based Accounting The purpose of
  provider based accounting (PBA) service is to
  allow customers to pay to their own ISPs for
  content delivered to them from various content
  providers, while the content providers will
  receive these payments from their own ISPs.

17
Accounting
18
Accounting

• Topics for Master Assignments
• Modelling of a Provider-Based Accounting Service
• Development a JAVA functional prototype for this
  architecture

19
Architecture group

• Bachelor and Master Assignments
• also external training (stage) and
• design projects (INF ontwerpopdracht)
• We also have contacts in the Industry (Ericsson,
  Lucent)
