What Technology Does Raysync Adopt to Transfer File Cross-border?
Cross-border file transfer and transnational transfer have to face the network transfer environment of ultra-long distance and weak network. If you want to transfer files fast, read on to learn how professional file transfer software Raysync transfers. For Congestion Handling: - More effective congestion judgment and treatment. - The recovery mechanism of packet loss judgment is carried out more accurately and timely. At present, the mainstream congestion judgment is designed based on the network situation data back to twenty years ago, and its basic assumption is that any packet loss reflects the network congestion. This assumption is completely out of line with the modern network situation. Packet loss in modern networks is often not caused by congestion factors. This disconnection leads to the transfer protocol often entering an overly conservative transfer state. The congestion detection algorithm of Raysync transfer protocol automatically collects the existing background transfer information on the path, and accurately judges the actual congestion situation according to the transfer speed, which is neither too conservative nor too radical, and can effectively make full use of the path bandwidth. For Packet Loss: - The standard TCP protocol tells the packet loss from two methods. - The receiving end continuously confirms the number of Dup-ACK. - ACK timeout. When the situation of packet loss always happens, the ACK is needed to judge the timeout and trigger to retransfer. Packet loss in modern networks is often burst, and it is common for multiple data packets to be lost at the same time on a connection. Therefore, standard TCP often relies on time-out to retransmit holes, which often leads to a waiting state of several seconds or even ten seconds, which makes transfer stagnate or even interrupt for a long time. This is one of the main problems affecting the efficiency of standard TCP. Raysync transfer protocol abandons TCP protocol's practice of using transfer message sequence as both transfer byte count and reliable transfer confirmation identifier and designs a brand-new ACK data algorithm. According to the ACK information returned by the transfer receiver, the transfer sender can accurately judge the packet loss and retransfer the data at the first time, instead of relying on the cumulative acknowledgment of multiple acks or the ack timeout timer to trigger the data retransfer, which greatly improves the transfer speed and transfer real-time. Raysync transfer protocol can make full use of large bandwidth network and transmit data at the fastest speed. In the application scenario of mass data distribution, it can help users to complete big data transfer and cross-border file transfer in the least time.

Difficulties and Future of Cross-border Transfer of Enterprise Data
The complete transfer process of data includes data generation, data transfer, and data reception. Cross-border data transfer is a bridge connecting the place where data is generated and the place where it is received, but the dilemma of data transfer is also derived from this part. Low efficiency of cross-border data transfer The branches of enterprises are scattered around the world, the headquarters of enterprises need to closely communicate with their branches so that the tasks can be finished efficiently. With the increasing amount of data, traditional network transfer methods such as FTP can hardly ensure the efficiency of cross-border transfer of large files, which seriously affects the project delivery schedule. Unstable cross-border data transfer leads to data damage or loss Cross-border transfer may face the problems of excessive transfer distance and poor network environment. Uploading and downloading data may be interrupted, and enterprises sometimes have to arrange special personnel to monitor data transfer. Even in this way, it is impossible to prevent the transfer data from being damaged. Unsafe transfer methods may also cause data damage or loss in the process of transfer. Many industries have very high requirements for data confidentiality, and data is maliciously stolen during cross-border transfer, which will eventually bring immeasurable losses to enterprises. Shenzhen Yunyu Technology Co., Ltd., as one of the leading manufacturers of enterprise big data exchange, perfectly solves the problems encountered in the process of transnational, long-distance, large files and massive files transfer by virtue of its self-developed data transfer core technology-Raysync transfer engine: Optimize transfer performance and efficiently transfer data across borders Raysync breakpoint resume function ensures that after the system is launched again, the remaining materials can be downloaded from the recording position .

Problems Faced by Transnational Transmission
As the development of economic globalization and Internet, especially the development of Internet information technology, it is easy to transfer data across borders. From a remote place, it only takes a few seconds to transfer files to an area of tens of thousands of kilometers. Transnational transfer of documents facilitates people's lives and makes communication less and less restricted. However, due to the uneven legal construction of data protection in various countries and frequent international network attacks, the security problem of data transnational transmission also faces unprecedented challenges. In recent years, more and more attention has been paid to network security because of issues related to personal information. In view of the problem of transnational data transmission, in order to protect the personal data of its citizens, many countries and regions have to some extent pursued localization of data collection, storage, and utilization, restricting or prohibiting the transnational flow of data. In order to break down barriers and restrictions on transnational data transmission in different countries and regions, promote the facilitation of global digital trade, more effectively implement law enforcement cooperation on cross-border data flow, and meet the actual needs of cross-border data transmission among enterprises, international organizations such as OECD and APEC have formulated a series of guidelines and policies to actively promote the liberalization of transnational data transmission. Traditional transnational transmission is facing great challenges, mainly due to the influence of network physical conditions when dealing with remote data or transnational data transmission, traditional FTP, mail, instant messaging tools will cause high delay and high packet loss rate due to network conditions, and the stability and quality of data transmission cannot be guaranteed. How to ensure the stability, safety and controllability of data transmission under the premise of long distance has become a huge technical bottleneck. 1) Network physical conditions affect the stability of data transmission; 2) FTP and other traditional transmission modes have high delay and packet loss rate seriously affects the stability of data transmission; 3) Data security and confidentiality cannot be guaranteed during remote transmission; To solve these problems, Raysync Transmission can make full use of the existing network bandwidth and provide stable and secure transnational data transmission services. It is mainly manifested in the high-performance transmission of TB-level files and massive small files, meeting the needs of enterprises for accelerated transmission of remote and transnational data under different scenarios. The utilization rate of broadband reaches 90%, the burden of redundant data is less than 1%, the cost of enterprise bandwidth is reduced, and the existing network resources are fully utilized. Point-to-point file transmission, full TLS encryption and AES-256 encryption support breakpoint resume, automatic retransmission and load balancing to ensure stable and secure transmission. At present, Raysync Transmission has provided Huawei, OPPO, vivo, Wanda group, Perfect World with large file data transmission solutions. It is believed that in the near future, data transmission will be more convenient and fast, allowing everyone to enjoy the fun of science and technology.
