	abstract = {In several smart-city applications the networks of the mass-transportation systems can be bases of investigations. In this paper we show how one can extract a network of connected stops from the General Transit Feed Specification (GTFS) feed of a given service provider. We have also implemented this process as a tool (gtfs2net) that is available for use at the GitHub page of the project. On of our most important finding is that since providers do not follow the specification in a coherent way regarding the use of parent stations the problem of close stops has to be manually handled. In order to show how our tool works in practice we have provided some extracted networks with their properties.},

	abstract = {In this paper we focus on the fast communication issues of the Big Data processing tasks shared between High Performance Computing systems. In our performance evaluation framework we designed and developed two traffic measurement tools in order to answer some theoretical questions related to congestion control in practice. The first one is based on iperf and tcpdump softwares to capture data flows of TCP and UDP sessions. Classification aspects of the measurement cases were: homogeneity of the traffics, number of parallel communication sessions, and implementation types of the TCP congestion control algorithm. Dozens of parallel traffic scenarios were executed in a dumbbell topology to evaluate effects of the massively parallel communication sessions in wireline local and metropolitan area networks. Since we found that connection oriented data transfer sessions have limited performance features during communication, we implemented a second communication tool named Fast Manager of File Transfer (FMFT). This application with transfer rate monitoring and regulation capability is based on parallel connectionless data transfer sessions supervised by a common connection oriented control session and provides better transfer rate than the classical file transfer mechanisms using TCP services. Methodology of the statistical analysis and highlights of this heterogeneous parallel communication mechanism are explained, too.},

	abstract = {Main issues of the Big Data processing imply high speed transmission between different nodes of the infocommunication system. Best effort based datagram delivery of the protocol data units requires bandwidth in the scale of n*10 Mb/s for time critical services. Although IntServ and DiffServ QoS mechanisms make possible for time critical data flows to be forwarded in reasonable conditions, high speed transmission of the big data in LAN/WAN environments remains hot topic. Different implementations of the TCP congestion control mechanism were developed in the last decades. The QoS strategies applied in LAN environment are weakly usable in wide area data networks producing low usage efficiency of the communication path traversing different ISPs. In our performance evaluation framework we developed an own measurement tool based on iperf and tcpdump software to capture data flows of TCP and UDP sessions. Classification aspects of the measurement cases were: homogeneity of the traffics, number of parallel communication sessions and implementation types of the TCP congestion control algorithm. High number of traffic scenarios were executed in a dump-bell topology. Statistical analysis methods were used to evaluate effects of the aspects mentioned above in the wireline local and metropolitan area networks.},
