Abstract:

[Context] Controlled thermonuclear fusion research has great political, economic, and social significance. China and major countries in the world have carried out comprehensive and in-depth cooperation in this field and the network-based scientific research collaboration has become an inevitable choice. [Objective] This study is to enhance the transmission performance of long-latency, high-bandwidth international links in response to the characteristics of different applications in international thermonuclear fusion research collaboration, and to ensure the smooth conduct of design collaboration and online experiments. [Methods] Relying on the China Science and Technology Network, this study investigates and applies various network data transfer acceleration methods to improve the network transmission performance between end-to-end applications and between dedicated high-performance data transfer nodes (DTNs). [Results] The testing and practical results verify that the methods proposed in this paper effectively support the network requirements for international thermonuclear fusion research design collaboration and online experiments.
