1. Integration & Interoperability Issues Michele Morganti Siemens Italy EUC Consultation Meeting on “Networking” – Bruxelles, May 2 nd, 2001

2. Presentation outline Interoperability vs. Integration Communications Paradigms vs. Telecomm. Services Vertical vs. Horizontal Segmentation Service Level Agreements vs. Legal Implications A key role for Terminals

3. Access Trends Physical Media GlassCopperAir Bandwidth Demand Ubiquity Demand the Last Mile

4. Access Trends Architectures QoS Guarantee Demand Point-to-Point Individual Access Centralized Control Pont-to-Multipoint Shared Access Distributed Control Cost Reduction Demand

5. Core Trends Switching Techniques Flexibility Efficiency Hierarchical Lightly Meshed “Flat” Heavily Meshed

6. Core Trends Switching Techniques QoS Guarantee Cost Reduction Packet Routing “Circuit” Switching

7. Hence … There could never be a single network solution fitting all needs and expectations. There will always be several different networks coexisting. Consequently, interoperability will always be a must. Partial, well focused integration of specific solutions, could eventually prove a plus in the longer term. Integration “per se” never made much sense …

8. Communications Paradigms vs. Telecommunications Services Dialog Lesson TV Show Consultation Conference Round Table Vote Support Mess One Some All OneSomeAll All parties on same Network !

9. Communications Paradigms vs. Telecommunications Services Dialog Lesson TV Show Consultation Conference Round Table Vote Support Mess One Some All OneSomeAll Multiple Networks involved !

10. Hence … A lot still needs to be done in terms of: Services Protocols Supporting Technologies

11. Upper (Service & Application) Levels Trends Vertical Segmentation Type of Offering Market Segment

12. Upper (Service & Applications) Levels Trends Horizontal Segmentation Value Chain Positioning Market Entry Strategy

13. Lower (Network Infrastructure) Levels Trends Vertical Segmentation Network Architecture Access Technology

14. Lower (Network Infrastructure) Levels trends Horizontal Segmentation Local vs. Global Market Focus Specific Assets and Legacies

15. Hence … A very composite market situation Even more complex interoperability problems Across networks Across levels

16. Service Level Agreements vs. Legal Implications Typical Service Level Agreement parameters: Speed, Bandwidth Delay, Jitter Bit Error Rate, Packet Loss Rate Etc. Other (implicit ?) parameters: Security, Privacy Safety, Liability Etc.

17. Hence … True Interoperability is only in minor part a technical problem …

18. Service Offering Trends Universal Ubiquitous Access WML WAP Gateway Vox ML Voice Gateway HTML Any Service or Application

19. Hence … Terminals (and in particular Personal Communication Devices) will definitely play a major role …
