We present a Scenario on how the Self-Managing Future Internet can be developed via a viable Evolution Path that starts with today's network models,

Research efforts at network design in the area of Autonomic Networking and Self-Managing Networks... more Research efforts at network design in the area of Autonomic Networking and Self-Managing Networks have reached a maturity level that forms a strong foundation toward standardization of architectural principles of the Self-Managing Future Internet. Therefore, an Industry Specification Group (ISG) on Autonomic network engineering for the self-managing Future Internet (AFI) has been established under the auspices of the European Telecommunications Standards Institute (ETSI). Upon its creation, the main stakeholders agreed to harmonize the previous developments and the most recent trends in the very vital field of autonomic and self-managing networks. Particularly, the life cycle of AFI is structured by Work Items providing the foundation for ETSI Group Specifications. So far AFI has been focusing on scenarios, use cases, and requirements for the autonomic/selfmanaging Future Internet, as well as on architectural reference model for autonomic networking and self-management. Most recently, AFI has continued with a new Work Item on requirements analysis and specification of implementation-oriented solutions for autonomics and self-management. At the same time, as a part of the global ecosystem, AFI is establishing strategic liaisons with the standards developing organizations and research community.

By doing so, design mistakes and implemen-tation faults can be detected in an early stage of the system design and imple-mentation process, i.e. before the newly developed system is shipped to the cus-tomer. This allows for reducing the overall development time and costs significantly. This paper reports on results in integrating testing into a model-based development process. Based on a common MOF-based infrastructure, ini-tial test are automatically derived from the system models. Subsequently, an ex-ecutable test code can be automatically generated from the test models and be-ing applied to the final system for quality assessment.

In characterizing the resilience properties of a system or individual functional entities of a system, the area of autonomics is extending the traditional scope and meaning of resilience in networks, by including self-diagnosing and self-repairing/self-healing behaviours, as well as proactive resilience to various types of challenges i.e. adverse conditions of operation and incidents (including fault-activations and security attacks and threats). This goes beyond the protection and restoration techniques for survivable networks found in protocols such as SDH, ATM, and IP-Fast-Re-route. What is becoming crucial for the global community is the establishment of standardized frameworks that can be applied for implementing interoperable systems that exhibit resilience properties in their own capacity and collaboratively as networked systems. This paper reports on a recently launched initiative in ETSI (European Telecommunications Standards Institute) that is aimed at standardizing resilience, survivability, autonomic fault-management and autonomic security management. We outline the types of concepts and architectural principles that are standardizable from resilience, survivability, and autonomic fault and security management point of view. We present and discuss a candidate evolvable architectural framework for standardization that unifies resilience, survivability and autonomic fault-management within a single holistic framework. It unifies the aspects by defining the responsible Functional Blocks (FBs) and their interworking in the realization of resi- ience, survivability, autonomic fault-management and autonomic security management in systems and networks. We show how research results in these areas can now be contributed to developing and relying on a commonly-shared (i.e. common baseline) unified standardized framework, by adopting, enhancing and evolving the framework presented in this paper as standardization activity (open to all technical experts/researchers to now join).

Autonomicity - realized through control loops, is an enabler for advanced self-manageability of network nodes and devices. Therefore, the specification and design of autonomic behaviors is required for each of the management functions defined by the well established FCAPS network management framework (Fault-, Configuration-, Accounting-, Performance- and Security-Management).

With continued improvements in the performance of SNMP data collection and serving methods, SNMP-based monitoring is now more applicable to real-time data collection, beyond traditional network management and trends gathering for capacity planning. Often, the user of an SNMP based monitoring system intends to make a selection of variables to be read over a duration during which monitoring is required, for example, just to get a snapshot of some resource utilization such as link utilization, traffic class utilization on some selected target routers when conducting network testing. In such cases, some kind of interactive monitoring system that provides the possibility to start and stop monitoring is often desired. The user of such a system requires an appropriate user interface through which selections of what to monitor can be made on-demand, and real-time traffic graphs can be displayed automatically.
