Michele Morganti Siemens Italy Integration & Interoperability Issues EUC Consultation Meeting on “Networking” – Bruxelles, May 2nd, 2001
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
the Last Mile Access TrendsPhysical Media Bandwidth Demand Air Copper Glass Ubiquity Demand
Point-to-Point Individual Access Centralized Control Pont-to-Multipoint Shared Access Distributed Control Access TrendsArchitectures QoS Guarantee Demand Cost Reduction Demand
Core TrendsSwitching Techniques Hierarchical Lightly Meshed Flexibility Efficiency “Flat” Heavily Meshed
Core TrendsSwitching Techniques Packet Routing QoS Guarantee “Circuit” Switching Cost Reduction
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 …

Hence … • A lot still needs to be done in terms of: • Services • Protocols • Supporting Technologies
Upper (Service & Application) Levels TrendsVertical Segmentation Type of Offering Market Segment
Upper (Service & Applications) Levels TrendsHorizontal Segmentation Value Chain Positioning Market Entry Strategy
Lower (Network Infrastructure) Levels TrendsVertical Segmentation Network Architecture Access Technology
Lower (Network Infrastructure) Levels trendsHorizontal Segmentation Local vs. Global Market Focus Specific Assets and Legacies
Hence … • A very composite market situation • Even more complex interoperability problems • Across networks • Across levels
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.
Hence … • True Interoperability is only in minor part a technical problem …

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