Cím:Performance evaluation of massively parallel communication sessions / Z. Gál, I. Varga, T. Tajti, G. Kocsis, Z. Langmajer, M. Kosa, J. Panovics
Megjegyzések: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.
