This paper describes an ontology model (conceptual model) based on the ITU-T Recommendation G.805 for transport network architectures. The goal is to take a step forward to the autonomic applications for transport network operation and management. Besides the conceptual model description and explanation, including its main elements (classes, properties and constraints), this paper also includes the description of the G.805 recommendation main concepts characteristics. Furthermore, the paper elaborates on the advantages of using an ontological model, as well as the technologies used for ontology conceptual modelling and ontology implementation.Finally, this paper presents a case study using a simple OTN unidirectional network, in which automated inferences could be verified. In conclusion, the methodology and reference conceptual model of transport networks presented here constitutes a contribution towards autonomic network applications.
The ambition is to build intelligent networks and intelligent cities by improving energy networks and energy supply. Lisbon Clients and Networks Direction (DRCL) has a close engagement with this project and one of the many initiatives driven is the improvement of smart public Lighting management, together with municipalities head offices, innovation clusters and lighting manufacture companies. The project is being developed by EDPD, LED lighting solutions, management systems suppliers, and R&D companies. The objective is the implementation of test scenarios comprehending traditional street lamps and lanterns replacement by LED light, energy efficiency measures, and ultimately the reduction of public lighting energy consumption. The project also includes the installation of sensors and the development of management system that can be remotely controlled with added features of flux reduction, associated with street movement, either by cars or people passing on the street, and a supervision center that can establish energy consumption profiles for each LED lamp.
The increase of regulatory pressure, the growth of energy demand and the recent trends in liberalization processes determine the continuous need for improvement in procedures. Lisbon operations area is part of the Portuguese Distribution utility-EDP Distribuição-essentially comprised by urban areas with more than 2.7million inhabitants concentrated in 2896 km2. The underground cables represent almost 70% of the 7 000km distribution network, and areas served by overhead lines are gradually becoming urban areas. Although Lisbon operations area only represents 3% of the Portuguese mainland, it covers 28% of the Clients and 27% of electric energy consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
