The main goal of the paper is to present a new application based on Agile-Kanban methodology. The application allows not only to visualize the development stage but also includes the possibility of inside-system cross-team cooperation for multi task and multi flow project. In the last chapter some examples of the usage of the application, gathered during the tests have been shown and concluded.
The P2P TV applications are becoming increasingly popular and packet streams generated by them may soon have significant influence on the traffic observed in the networks of many ISPs. The knowledge about the properties of aggregated P2P TV traffic is therefore important for selecting an appropriate approach to dimensioning the network interfaces. In this paper we present the analysis of self-similarity...
In the paper we investigate the methods of constructing the routing tree in WiMAX networks with mesh topology. The concept of network efficiency optimization by building the routing tree characterized by selected topological properties that are independent on network load is presented. As an important partial result, correlations between topological parameters of the tree and network efficiency have...
Przedstawiono wyniki analizy własności samopodobieństwa zagregowanych strumieni ruchu pakietowego mierzonego w sieci UMTS. Przedstawione wyniki pokazują, że ruch generowany przez sieć komórkową ma własności samopodobieństwa oraz dalekosiężnej korelacji (Long Range Dependence). Do jego modelowania konieczne jest zastosowanie odpowiednich modeli matematycznych. W artykule przedyskutowano różne aspekty...
Omówiono model analityczny usługi GPRS, oparty na łańcuchach Markowa i opisie procesu napływu danych na poziomie paczek pakietów. Otrzymane wyniki porównano z analogicznym modelem, opisującym napływ na poziomie sesji GPRS.
The paper deals with flow allocation problems in IP networks using open shortest path first (OSPF) routing. Its main purpose is to discuss and propose methods for finding settlements of OSPF link weight system realising the assumed demand pattern for the given network resources (links capacities). Such settlements can result in a significantly better network performance, as compared with the simplified...
