1. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin Some Ideas on Management of IP Networks Towards Active IP Networks Dr.-Ing. Stefan Covaci Intelligent Mobile Agents Centre of Competence GMD FOKUS covaci@fokus.gmd.de

2. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin Drivers Applications‘ demand for customised communications - beyond standards Customised means: – QoS, location and „real-time“ aware from the applications perspective -> the network becomes a resource of the application – applications aware (during the appl. session) from the network perspective Manage QoS and topology in IP Networks dynamic nature (in service) distributed between users and owners (outsourcing- based architectures)

3. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin Drivers (cont) Need for differentiation (NO, VAR) –open the service / application creation & deployment –open the service / application management Light/Small footprint terminals, Capable NEs, asynchronous delegated operation –processing (autonomous) in the network

4. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin Key Issues Introduce and dynamically manage state –ex. Signalling (intserv) for diffserv application and services models –what resources (abstractions, APIs) – what models for code distribution, execution, co-operation -> autonomy properties the model of the Management Solution –from CNM (static, configurable) towards a Programmable / Active Network

5. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin New Network Model Passive Network Store - Forward Level of Abstraction (standardisation): protocol Active Network Store - COMPUTE - Forward Level of Abstraction (standardisation): –programmability of infrastructural resources (communication & processing) –programming model

6. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin New Management Model The application includes the business level management solution (owned by the customer - a distributed virtual enterprise) includes Work Flow components The Network can / should provide support management services (dynamically) configurable Work Flow (management) Engines -integration with underlying communications management (service and network management), processing management and information management via dynamic brokerage dynamically configurable Business Object communications services

7. Management of IP networks and services AIMS‘99 Workshop Heidelberg 11-12 May, 1999 Dr. Stefan Covaci GMD FOKUS, Berlin Questions What to standardise first? –Interoperability ref. points –Business (markets) separations - flexibility What are the migration paths towards active applications and active network nodes? What are the outstanding issues?
