    Preliminary study of big data transfer over computer network
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 421-427

    The transfer of Big Data over computer network is important and unavoidable operation in the past, now and in any feasible future. There are a number of methods to transfer the data over computer global network (Internet) with a range of tools. In this paper the transfer of one piece of Big Data from one point in the Internet to another point in Internet in general over long range distance: many thousands kilometers. Several free of charge systems to transfer the Big Data are analyzed here. The most important architecture features are emphasized and suggested idea to add SDN Openflow protocol technique for fine tuning the data transfer over several parallel data links.

    Keywords: data, Linux, transfer, SDN, Openflow, network.

    The New Use of Network Element in ATLAS Workload Management System
    Computer Research and Modeling, 2015, v. 7, no. 6, pp. 1343-1349

    A crucial component of distributed computing systems is network infrastructure. While networking forms the backbone of such systems, it is often the invisible partner to storage and computing resources. We propose to integrate Network Elements directly into distributed systems through the workload management layer. There are many reasons for this approach. As the complexity and demand for distributed systems grow, it is important to use existing infrastructure efficiently. For example, one could use network performance measurements in the decision making mechanisms of workload management systems. New advanced technologies allow one to programmatically define network configuration, for example SDN — Software Defined Networks. We will describe how these methods are being used within the PanDA workload management system of the ATLAS collaboration.

    Keywords: ATLAS, PanDA, distributed computing, workload management system, decision making mechanisms, network, network performance measurements, software defined networks.
