This paper is concerned with the parameter setting problems of some delay-based versions of TCP (TCP Vegas and the recently developed Vegas-based FAST TCP) from a game-theoretic point of view. It is shown that if the TCP Vegas' users are assumed to be selfish in terms of setting their desired number of backlogged packets in the buffers along their paths,… (More)
The Intermon project aims to enhance inter-domain traffic analysis in large scale Internet infrastructures. An important part of the system is a set of simulators especially designed for inter-domain scenarios based on measurements from the real network. Simulation results are analyzed using the built-in visual data mining system. This paper presents the… (More)
In this paper we investigate the impact of customer loyalty on the price competition between local Internet Service Providers who sell Internet access to end-users. The main contribution of this paper is threefold. First, we develop a repeated game, and show how cooperation between ISPs resulting in higher profits can be enforced through a threat strategy… (More)
This paper represent an approach of applying the graphical visualization methods to the educational process. The Virtual electrotechnologic factory is created based on theory and contains the theory itself. The technology utilized during the process of the development was the Flash multimedia platform. This allowed us to visualize all the theoretical… (More)
The paper describes the e-learning system and virtual laboratory that are intended for implementation into electrotechnology-oriented study programs. It is a short description of the main functions of the systems as well as the technologies used for the implementation.
This paper presents a new approach to use of the animations as a tool for education. Our approach is focused on the methodology of designing the animation rather than on the study whether it is or is not beneficial in the educational process. We will introduce the animation as a tool, present commonly used tools for development and then introduce a basic… (More)
