3. DOT’98 Workshop Heidelberg, 1-2 September 1998 Rationale Intrinsic bottlenecks in traditional IN architecture can lead to poor performances High expenses in switching SW design and maintenance New technologies for network-unaware distributed applications Mobile code supports dynamically reconfigurable network structures * Adaptive broadband service provisioning architecture * Open switching platforms able to accommodate mobile code

5. DOT’98 Workshop Heidelberg, 1-2 September 1998 Main objectives to identify and explore B-IN service and network architectural issues combining DOT/MAT to explore benefits given by DOT/MAT to service provisioning to investigate the implications of DOT/MAT on user mobility (VHE) to perform experiments to validate the proposed solutions

6. DOT’98 Workshop Heidelberg, 1-2 September 1998 Distribution of intelligence in the network: traditional IN approach INSIGNIA Intelligent Broadband Network B-IP B-SCP B-SSP TE CCAF Trigger detection B-CCF C-Plane event correlation B-SSF B-SCF Main service control static (i.e., not dynamically relocatable into other physical elements) SLP for B-SCF SLP Service assistance B-SRF static SLP for B-SRF SLP

7. DOT’98 Workshop Heidelberg, 1-2 September 1998 Distribution of intelligence in the network: MARINE approach SCE (Service Creation Environment) SMS (Service Management System) SEN (Service Execution Node) B-SS&CP (Service Switching and Control Point) TE (Terminal Equipment) SCEF SMF SLP download DOT/MAT-based SLP for B-SCF DOT/MAT-based SLP for B-SRF Main service control B-SCF B-SRF Service assistance communication B-SSF C-Plane event corr. B-CCF Trigger detection CCAF

8. DOT’98 Workshop Heidelberg, 1-2 September 1998 MARINE applies DOT/MAT to the design and deployment of IN SLPs/SDTs, which can be distributed between different network nodes according to time-varying service needs

9. DOT’98 Workshop Heidelberg, 1-2 September 1998 Roles of MARINE network systems SCE: create and test MA-based services SMS: store services and deploy them in the remaining PE, service management SEN: combination of B-IP and B-SCP functionality by hosting B-SCF/B-SDF, M- SCF/M-SDF and B-SRF FE B-SS&CP: combination of B-SSP and B-SCP functionality by hosting B-CCF, B-SSF, B- SCF/B-SDF and M-SCF/M-SDF FE
