Runtime Semantic Interoperability for Gathering Ontology-based Network Context

Abstract

Abstract-The trends for pushing more operational intelligence towards network elements to achieve more context-aware and self-managing behavior often requires elements to gather network knowledge without necessarily binding explicitly to all of the potential sources of that knowledge. Though event-based publish-subscribe models allow efficient distribution of knowledge where the event types are known globally, dynamic service chains, ad hoc networks and pervasive computing application all introduce a more fluid and heterogeneous range of context knowledge. This requires some runtime translation of knowledge between sources and sinks of network context. This paper builds on existing mapping techniques that use ontological forms of existing management information models to examine the extent to which these can be employed for runtime semantic interoperability for network knowledge. It presents results in developing a management knowledge delivery framework based on existing models and platforms, but which offers a more decentralized knowledge exchange mechanism.

Real Time Semantic Interoperability in Ad Hoc Networks of Geospatial Data Sources: Challenges, Achievements and Perspectives

“…Secondly, because ad hoc networks are dynamic, the ontology mapping process must be automated (Keeney et al 2006). However, as of today, there is only a few ontology mapping approaches that are automated (e.g., Montanelli and Castano 2008;Bakillah and Mostafavi 2010), but they still require some user input.…”

“…The concept of "real time" semantic interoperability, in this context, goes beyond the concept of "run-time" semantic interoperability. While the latter refer to the idea that available data can be integrated "on demand," or "on-the-fly" (Keeney et al 2006), real time semantic interoperability means that a semantically interoperable system is reactive to the changes that occur in the network. According to Kopetz (2011), in a realtime computer system, the correctness of the system behaviour, which is the sequence of output of the system, "depends not only on the logical results of the computations, but also on the physical time when these results are produced."…”

“…Several semantic interoperability frameworks have been proposed in recent years, both in the geospatial domain (e.g., Bishr 1998;Brodeur et al 2003;Kuhn 2003;Kavouras et al 2005;Bakillah et al 2006;Lutz and Klien 2006;Hess et al 2007;Cruz and Sunna 2008) and in the larger information system community (Kalfoglou and Schorlemmer 2003;Park and Ram 2004;Keeney et al 2006;Euzenat and Shvaiko 2007). In ad hoc networks, the data sources that have to interoperate are not known in advance and are dynamically changing.…”

Challenges for federated, autonomic network management in the Future Internet

“…embedded in contracts or policies, and to ascertain the extent to which these processes must be context-specific and amenable to automation. [14], [15]. Using these techniques it is possible to model: a) the resources being managed, b) the context used in communication services, and c) the policies used to express governance.…”

An Ontology-Based Approach to the Description and Execution of Composite Network Management Processes for Network Monitoring

“…The use of ontologies to represent information related to the network management scope has been addressed to a significant extent in recent research [8,9,10,11,12,13]. In the work presented here, the line started in [8] is extended by using a common representation ontology to formalize a set of specifications for network traffic monitoring.…”
