Abstract:

[Objective] We use the SDN architecture network to optimize the selection of high-energy physical data transmission paths, and improve the data transmission efficiency between high-energy physics cooperation units. [Methods] In this paper, we use the service-oriented network performance measurement framework perfSONAR, GRE-based virtual network technology, and SDN-based control technology to achieve our goals. [Results] We propose a method for network performance measurement and performance optimization in a high-energy physical grid environment. First, SDN technology and virtual network technology are used to construct a high-energy physical data sharing virtual private network based on the SDN architecture in the high-energy physical grid environment. Then, perfSONAR is used to design and implement a network performance measurement and visualization platform. Given the results of network performance measurement in the high-energy physics grid environment, the optimal data sharing path between two nodes can be selected based on the optimal path calculation method proposed in this paper. [Conclusions] Test results show that this method can improve the efficiency of data sharing, and provide a reliable guarantee for high-speed and stable data transmission between nodes in the high-energy physics grid environment.
