Management in the Future Internet is not ignored, but rethink
The FI is no longer a service agnostic transport network, but a service cooperating (federated) with other services
Orchestration of these services to fulfill business objectives is a must
Here is where management, understood in wide sense, plays its role

Which are the limitations of the current Internet to face mean term and future expectations ?

Limitation: Lack of user’s mobility experience
• Requirements – Cooperation and mobility of networks
• Trends – Look for more advanced (self)management systems
• Challenges – Scalability, security (trust)

Limitation: The network is unaware of the services it supports
• Requirement – Future Internet Services support
• Trends – Service-driven, business-driven network management
• Challenges – Refinement of service goals into network configuration

Limitation: Disconnection between Internet governing policies at different levels
• Requirement – Deployment of consistent policies
• Trends – Extend the policy-based management paradigm to work with the
concept of a “continuum of policies” (interrelated policies)
Business View: SLAs, Processes, Guidelines, and Goals
System View: Device- and Technology-Independent Operation
Administrator View: Device- Independent, Technology-Specific Operation
Device View: Device- and Technology-Specific Operation
Instance View: Device-Specific MIBs, PIBs, CLI, etc. Implementation

Limitation: Interaction between different domains is predetermined or requires tedious manual
negotiations • Requirement
– Service coalition supporting mechanisms • Trends
– Allow and define dynamic negotiation processes and mechanisms between domains (Interdomain Management)
• Challenges – Efficient and robust algorithms needed

… and last but not least
Lack of protection against intentional attacks (DDoS, trojans, etc)
Lack of protection against non-intentional attacks (misconfigurations)

… we rely on the Internet and we expect more and more
Innovation and Investment, particularly in management, is necessary
• The question is: – is the road smooth and clear?
or
– are there threads which might jeopardize the impact of this innovation?

Threads
• Trying to cater for current and future requirements of the Internet may lead to: – A proliferation of coexisting incompatible protocol stacks – Deployment of a plethora of ad-hoc solutions to control E2E QoS in mobile
ubiquitous environments – Emergence of independent sources trying to control the network (like the
applications themselves) – Deployment of more and more policies without the appropriate mechanisms
to have a clear view of the consequences and impact on all the affected resources and supported services
– Allowing for complex mechanisms between parties involved in service offering
• The attempt to address the ever increasing number of requirements causes the network to become too complex to be properly managed resulting in unpredictable behavior or even collapse

Conclusion
• A New Internet is necessary to tackle the above challenges – In particular: an Internet laying on Autonomic Communications
principles with embedded self-management capabilities

Conclusion
• A New Internet is necessary to tackle the above challenges
• But – A careful planning and design, likely holistic, is required to avoid
a counter effect
