“…When context changes, the above ensures that the functionality of the appropriate control loops are changed to match the new nature of what is being governed [41]. Similarly, if the system is performing a goal and needs to temporarily change its focus (e.g., examine sensor data from a different data source and correlate those data with the data that it is currently examining), the above processes can be used to again adapt the control loop.…”

The purpose of autonomic networking is to manage the business and technical complexity of networked components and systems. However, the lack of a common lingua franca makes it impossible to use vendor-specific network management data to ascertain the state of the network at any given time. Furthermore, the tools used to analyze management data are all different, and hence require different data in different formats. This complicates the construction of context from diverse information sources. This paper describes a new version of the DEN-ng context-aware policy model, which is part of the FOCALE autonomic network architecture. This model has been built using three guiding principles: (1) both the context model and the policy model are rooted in information models, so that they can govern managed entities, (2) each model is expressly constructed to facilitate the generation of ontologies, so that

“…Static behavior is thus "programmed" into FOCALE by designing a set of FSMs; dynamic behavior is defined by altering one or more FSMs. Context-aware policy management [2][3] governs the autonomic control loop. This enables context to select the set of policies that are applicable; policies are used to then define the functionality allowed.…”

“…Any ManagedEntity can have contextual information associated with it. We model context [40] The purpose of the ContextDataDetails association class is to define the particular semantics of how ContextData relates to Context. This enables different types of ContextData, each modeling a specific aspect of an overall Context, to be aggregated together with their own semantics.…”

Abstract. Currently, there is an increasing tendency to migrate the management of communications and information systems onto the Web. This is making many traditional service support models obsolete. In addition, current security mechanisms are not sufficiently robust to protect each management system and/or subsystem from web-based intrusions, malware, and hacking attacks. This paper presents research challenges in autonomic management to provide self-protection mechanisms and tools by using trust and reputation concepts based on policy-based management to decentralize management decisions. This work also uses user-based reputation mechanisms to help enforce trust management in pervasive and communications services. The scope of this research is founded in social models, where the application of trust and reputation applied in communication systems helps detect potential users as well as hackers attempting to corrupt management operations and services. These so-called "cheating services" act as "attacks", altering the performance and the security in communication systems by consumption of computing or network resources unnecessarily.
