Abstract

The experience and results of the development and implementation of a technical-documentary information management system in the enterprise Nuclenor (Power plant of Santa María of Garoña) are presented. In order to share knowledge and contribute as far as possible to the dissemination of this kind of systems in other enterprises and organizations, we explain the organizational strategy and objectives defined by Nuclenor to carry out this project, and analyze the functional requirements of the system. From a technical perspective the development methodology used and the support technological model of the system is presented. Finally, we review the results and benefits of the project for the enterprise, and comment the research lines currently open.

Abstract

Nowadays, P2P applications are commonly used in the Internet being an important paradigm for the development of distinct services. However, the dissemination of P2P applications also entails some important challenges that should be carefully addressed. In particular, some of the important coexistence problems existing between P2P applications and Internet Service Providers (ISPs) are mainly motivated by the inherent P2P dynamics which cause traffic to scatter across the network links in an unforeseeable way.\r \r In this context, this work proposes a collaborative framework of a BitTorrent like system. Using the proposed framework and based on the exchange of valuable information between the application and network levels, some novel techniques are proposed allowing to estimate and control the traffic impact that the P2P system will have on the links of the underlying network infrastructure. Both the framework and the presented techniques were tested resorting to simulation. The results clearly corroborate the viability and effectiveness of the formulated methods.
