The article has been presented on the international astrophysical conference in Arkhyz, Russia - July, 2014. It has been published in «Astrophysical bulletin» - December, 2014. Authors: Khoruzhnikov S., Grudinin V., Sadov O., Shevel A., Titov V., Kairkanov A. The transfer of Big Data over computer network is important and unavoidable operation in the past, now and in any feasible future. A large variety of astronomical projects produces the BigData. There are a number of methods to transfer the data over global computer 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 discussed idea to add SDN Openflow protocol technique for fine grain tuning the data transfer process over several parallel data links. Key words: astronomical applications, data transfer, Linux, SDN, Openflow, network

Published in Digital scientific magazine «Modern problems of science and education» Abstract: The purpose of the study are software-defined network (SDN) OpenFlow and effectiveness of their approach to build a network storage. Here we present the study how to build up and study of operating characteristics of software-configurable networks. Prototyping tools for managing network resources and data flows on the basis of the SDN are described. The estimation of the SDN approach for data centers (DC) and the distributed storage systems is observed. We describe experiments with various modifications of OpenFlow controller NOX and set out the specifics of the use of various software and hardware OpenFlow switches. We provide comparative performance results of specific QoS methods. A description of the main problems of existing implementations of OpenFlow SDN components identified during the research, and recommendations on possible ways to address them are provided.
