  1. ISSRE04 WITUL Workshop Rennes . November 2 . 2004

  2. Goals of our paper and talk • Overall- Goal: to possibly improve the applicability of UML and ITU Languages in large ‘modern’ time-constrained Telecommunicationprojects such as Daidalos • to show the present usage of UML/SDL in Daidalos • to discuss Daidalos in the general and OMG context • to possibly propose contributions to the OMG and ITU concerning (testability – only in the paper- and) model driven adaptability and ‘reactive reliability’ based on Reflection

  3. The Daidalos Visionis a world in which … • Mobile users can enjoy a diverse range of personalized services – seamlessly supported by the underlying technology and transparently provided through a pervasive interface • Mobility has been fully established through open, scalable and seamless integration of a complementary range of heterogeneous network technologies • Network and service operators are able to develop new business activities and provide profitable services in such an integrated mobile world

  4. Daidalos Reality • IST FP6 • STRATEGIC OBJECTIVE 2.3.1.4: MOBILE AND WIRELESS SYSTEMS BEYOND 3G • Daidalos - Designing Advanced Interfaces for the Delivery and Administration of Location independent optimised personal Services. • Start 01.11.03 - Duration 24 + Duration 24 + 6 month • End 31.05.06 • 49 Partners • ~ 100 people working in parallel

  5. 3rdP SP 3rdP SP 3rdP SP WP4 Pervasiveness WP3 Service Provisioning Platform WP2 Access Networks Daidalos Overview (trivial version) • Context • Location • … • Access tech • Signal Q • … • Provider • … • Mobility • Dynamics

  6. Daidalos Overview (confusing version)

  9. Modelling in Daidalos so far • Convincing the non-convinced (ongoing) • Push Telelogic Tau – • license agreement, training • Detailed UML/SDL modeling in Terminal Mobility • Collect all type of input from all parties – ppt, visio, Rational, EA • Convert the input to Tau • 1st Tau integration: 1Workspace, 1project/view-element • WP-organization-view • functional-component-view • scenario-view (“Mobile University”, “Automotive”) • 2nd Tau integration: 1 Workspace 1project for all => inconsistencies become visible

  10. High-level elements of the Daidalos service framework • Mobility • Context awareness – Pervasiveness • Service discovery and composition • Both operator- and user-orientation • Heterogeneity both in the technology and provider domain • Cope with heterogeneity in a technology independent manner

  11. Daidalos standardization context: OMG – ISO/ITU • OMG e.g. EDOC (Enterprise Distributed Object Computing) • Joined ISO JTC 1/ITU SC 7ITU ODP, X.9xx • CORBA centric

  12. Daidalos context: Adaptability – Reflection - Reliability • The case for Reflective Middleware – CACM June 2002 • Reflective Middleware Approach to …. Grid Middleware • Exploiting Reflection in Mobile Computing Middleware • Multi-Level Reflection for Fault Tolerant Architectures • Reflection, Self-Awareness and Self-Healing

  13. Reliability Adaptability Proactive Reactive …………. Reflective structural behavioral Daidalos - Integrated Reliability and Adaptability Model-driven …………. …………. …………

  14. Conclusion concerning UML and ITU Languages … • Address UML/ITU Languages applicability etc. in ‚real‘ projects: large, time constrained • A small testing and an UML/SDL etc. converged environment with improved • semantics and • treatment of time could support this goal • (see TTCN-3 below) • Continue work of Question 17 of ITU-T SG 17 and ETSI STF 250: UML profile for Communication Systems

  15. Conclusion concerning UML and ITU Languages … • Evaluate Reflection both in the context of Reliability and Adaptability as possible extension of the UML MOF • evaluate related effort to exploit UML action semantics to provide Reflection • Compare/align(?) • TTCN-3-Testsystem_to_SUT with/to • UML/MOF-based ReflectiveArchitectures
