;In the digital world, the rate of data growth far exceeds the rate of increase in bandwidth. Digital data must flow as quickly and reliably as possible to all parts of the world. This is very important for every company committed to internationalization. The data transmission methods are all based on the TCP communication protocol. TCP has its inherent characteristics of reliable transmission and is also the most widely used data transmission protocol on the Internet. However, the flow control problem of TCP in long-distance transmission is always difficult to overcome. File transfer protocol such as SMB, FTP, NFS, etc. Facing long-distance and high-latency network environments, their transmission efficiency is difficult to meet the needs of enterprises. This research is aimed at several UDP-based file transfer protocols, including Tsunami for open-source software, Presto File Server and Signiant. Compare their differences in practical application architecture, analyze their advantages and disadvantages, and experiment with different transmission efficiency under the distance is indeed much better than TCP transmission. After evaluating the requirements, software functions, features and costs, the case company finally adopted the Signiant solution to improve the efficiency of long-distance file transmission and save manpower.
