As the speed and the dynamic range of computer networks evolve, the issue of e cient tra c management becomes increasingly important. This work describes an approach to tra c management using explicit rate information provided to the source by the network. We present an asynchronous distributed algorithm for optimal rate calculation across the network, where optimality is understood in the maxm...

This paper aimed to design and implement a new hybrid intelligent technique called expert network. The main purpose of this expert network is to use it as a management tool assist network administrator in his job regarding the monitoring process of network performance. Here, the management task that uses this expert network was how to detect a fault (i.e. fault detection) that may be occurred o...

In this paper, we review a visual approach and propose it for analysing computer-network activity, which is based on the use of unsupervised connectionist neural network models and does not rely on any previous knowledge of the data being analysed. The presented Intrusion Detection System (IDS) is used as a method to investigate the traffic which travels along the analysed network, detecting SN...

Over recent years, we have experienced a dramatic development in computer-based communications and networking. The combination of relatively cheap computing power and the increasing transmission capability of telecommunications infrastructures have made possible to offer new advanced services. However, the complexity and sophistication of those services and of the underlying supporting infrastr...

pollution control is based on correctly measuring pollutant concentrations but, at the moment,the principal european cities only monitor pollution levels by means of a few fixed stations co-located inselected points of the urban layout far from hotspots and/or by means of meteorological prediction models offuture pollution. few cities integrate the information from both sources. the implementat...

Information managers at each of the 26 sites in the Long Term Ecological Research (LTER) Network face many challenges managing structurally and thematically diverse ecological data sets collected by LTER scientists. Since the LTER’s inception in 1980, LTER information managers have partnered with computer scientists to seek innovative information management solutions. This panel of three comput...

Leading in the innovation economy [1] requires an ability to create, comprehend, and utilize dynamic and distributed knowledge assets. This must be accomplished in a reliable, timely, and cost effective manner. Text mining technology has great potential to enhance knowledge management systems because it provides an objective analysis (reliable) of existing knowledge assets (cost effective) in a...

Enterprise network security management is a complex task of balancing security and usability, with tradeoffs often necessary between the two. Past work has provided ways to identify intricate attack paths due to misconfiguration and vulnerabilities in an enterprise system, but little has been done to address how to correct the security problems within the context of various other requirements s...
