  1. Michele Morganti Siemens Italy Integration & Interoperability Issues EUC Consultation Meeting on “Networking” – Bruxelles, May 2nd, 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. the Last Mile Access TrendsPhysical Media Bandwidth Demand Air Copper Glass Ubiquity Demand

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

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

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

  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 Paradigmsvs. Telecommunications Services One Some All One Dialog Lesson TV Show All parties on same Network ! Round Table Consultation Some Conference All Vote Support Mess

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

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

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

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

  14. Lower (Network Infrastructure) Levels trendsHorizontal 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 Agreementsvs. 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 TrendsUniversal Ubiquitous Access Any Service or Application HTML WAPGateway WML VoiceGateway Vox ML

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