Introduction Economic considerations are and have been a part of Network Management solutions. The progressive application of deregulation to the Global and National Telecommunications industries have created a situation where the economic elements to be considered in the design of network management solutions, have become dominant. The reason for this, is that fully deregulated markets create ...

The vision for future telecommunication systems is considered as a representative example of a complex adaptive organization, where several elements, with various computational capabilities and network resources, are interconnected. The increased complexity and the continuously changing network environment make more intense the need for automation and for localized network management tasks. Sel...

The ever-evolving nature of telecommunication networks has put enormous pressure on contemporary Network Management Systems (NMSs) to come up with improved functionalities for efficient monitoring, control and management. In such a context, the rapid deployments of Next Generation Networks (NGN) and their management requires intelligent, autonomic and resilient mechanisms to guarantee Quality o...

In operations of increasingly complex telecommunication networks, characterization of a system state and choosing optimal operation in it are challenges. One possible approach is to utilize statistical and uncertain information in the network management. This paper gives an overview of our work in which a Markov Logic Network model (MLN) is used for mobile network analysis with an RDF-based fac...

In Telecommunication networks, a high-performance and reliable management of alarm messages is more important than in traditional IP networks. TLC networks comprise up to thousands of heterogeneous Network Elements (NEs) and they generate high alarm traffic due to bad weather, correlated faults and logging activity. In this scenario, alarm messages have an extreme informative value and cannot b...

The purpose of this article is to describe the results of a clinical trial in which telephonic case management was evaluated as a supplement to substance abuse treatment. An interactive voice response system (IVR) was developed by the research team for use in the case management of randomly assigned participants in a clinical trial research project. The features of the software program facilita...

This paper describes a post-graduate program in Computer Network Operations, Internet Technology and Operating Systems' Support, organized by the Federal University of Rio de Janeiro and which has had a considerable success. One of the main contributions of this paper is the discussion of an appropriate curriculum for computer network managers. The paper also focuses on the main objectives and ...
