Initial-Stage Examination of a Testbed for the Big Data Transfer Over Parallel Links. The SDN Approach

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
