Management
of
IP networks
and services
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 (outsourcingbased architectures)

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

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

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

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

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?
