RationaleIntrinsic bottlenecksin traditional INarchitecture can leadto poor performances
High expenses inswitching SW designand maintenance
New technologiesfor network-unawaredistributedapplications
Mobile codesupports dynamicallyreconfigurablenetwork structures
* Adaptive broadband service provisioning architecture* Open switching platforms able to accommodate mobile code

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

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
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

Achievements/ongoing activities• Selection of services for the trial
• Stage 1 descriptions of services• Assessment of the computing
environment• Analysis of functional network
architecture with the introduction of DOT/MAT
• Analysis of agent support in IN devices• Sequence/collaboration diagrams
between service objects• Analysis of IN/CORBA interworking for
backward compatibility
