“…Therefore, SAGE2 needs to be improved just as SAGE was improved. One area of research uses OpenFlow to avoid congestion in SAGE [6]. We also will try to apply this research to SAGE2 and to contribute to e-Science in our future work.…”

“…For comparative purposes, we implemented a simple functionality that attempts reallocation in the same way as the previous functionality [5] only when a new application starts. Under the simple functionality, the OpenFlow controller calculates a route whose bandwidth utilization is the smallest using Dijkstra's algorithm only when a new flow is generated.…”

“…However, this functionality did not focus on network congestion, but on network failure occurrence. Therefore, our research team has proposed a dynamic routing functionality triggered by user interaction in [5]. This functionality verifies that reallocating routes of flows is effective for keeping their throughput when network parameters such as bandwidth and latency changes.…”

“…This failure avoidance functionality, however, focused on only a network failure event, and never considered network parameter changes due to other events. In subsequent research, our research team proposed and developed a dynamic routing functionality to avoid network congestion using OpenFlow when a network parameter change triggered by a user interaction such as window movements on a tiled display system was detected [5]. The overview of the dynamic routing functionality to avoid network congestion is shown in Figure 4.…”

A large amount of scientific data is generated through computation and analysis. Also, today's scientific research necessitates an aggregation of diverse expertise from experts with different backgrounds. Therefore, visualizing and sharing these data among scientists in an intuitive and easy manner is of more importance in scientific collaborative research than ever. We have focused on SAGE, a middleware that realizes a large-scale remote visualization leveraging network streaming technique as a promising building block technology. However, no advanced network control function for efficient use of the network is equipped with SAGE although SAGE relies on a network streaming techniques. Our previous research integrated a functionality that detected network failures avoided such failure by rerouting network flows of SAGE into the functionality.Nonetheless, a network congestion avoidance functionality to adapt a collection of network flows generated by SAGE to the underlying network has not been developed yet. In this paper we explore the feasibility of a reallocation-based dynamic routing functionality for SAGE, with which all network flows on the network are rearranged. For feasibility research, we perform simulation Rev Socionetwork Strat (2015) 9:1-18 2 experiments to observe the behavior of the functionality. The evaluation confirms that our proposed functionality works correctly and brings better throughput for each flow.

A Tiled Display Wall (TDW) is one of the visualization systems, which is appropriate for visualization of large-scale data. Although the scientific area needs an easier and cheaper TDW than the current one, a large-scale TDW is still too expensive to build individually. Given that, it is advisable to share the large-scale TDW among scientists who need to use it. To share a TDW, a variety of visualization middleware and applications should be installed on it because scientists use a different one of them depending on their data and purpose. However, there is a problem that it is difficult to coexist multiple visualization middleware and applications on a TDW because there are conflicts of library versions among them. To solve this problem, we propose a switching mechanism of visualization middleware and application using Docker. By using the proposed mechanism, administrators just need to deploy Docker images with visualization middleware and applications on a TDW, and then users can use them without the conflict problem. In the evaluation, the proposed mechanism is shown to have practically and scalability.
