How to Transfer Large Files and a Large Number of Small Files Faster in Cross-border File Transfer?
There are many documents with complex and diverse formats, how can large files be transmitted at the fastest speed? Transfer large files directly or split into multiple small files? Let's look at a set of test data first: In the same test environment, we transfer 10GB large files and 100,000 small files from Beijing Alibaba Cloud to New York Alibaba Cloud via FileZilla FTP. The difficulty of large file transfer is the large data volume, and the difficulty of mass small files is a large number of files. Using traditional file transfer tools for transfer, no matter which one is transmitted first, it will bring great pressure to the server in the process of file transfer, and the transfer efficiency is definitely not ideal. The cross-border transfer must face the ultra-long distance and weak network environment. The high latency and high packet loss rate caused by network problems can directly affect the efficiency of the file transfer. In the same test environment, let's try it with a professional file transfer tool from Beijing Alibaba Cloud to New York Alibaba Cloud. The transfer data shows that in response to cross-border file transfer, 10GB large files need to be transmitted for 34 hours. After using professional file transfer tools, the speed is reduced to 7 minutes and 30 seconds, and the efficiency is improved by 272 times; In the transfer of 100,000 mass small files, the transfer time is reduced from 168 hours to 1 minute and 50 seconds, and the transfer timeliness is improved by 5522 times. For the problems of large file transfer, massive small file transfer, cross-border file transfer, cross-border file transfer, file sharing, file synchronization, and point-to-point transfer, experts in large file transfer solutions can seek help from Raysync.

How to Solve the Problem of Cross-border File Transfer in the Global Layout of Enterprises?
In the first half of 2020, enterprises are facing a "great shock" in the global layout, and international trade, cross-border investment, and population mobility have all experienced an unprecedented sudden drop trend. In the complex domestic and international environment, the offline business operation of enterprises is blocked, the online business is surging, and the problem of slow cross-border file transfer is exposed again. Three major problems, such as the rapid increase of data volume, inefficient transfer of large files, and unstable cross-border transfer, are forcing modern enterprises to enhance their digital operation capability. In dealing with the problem of cross-border file transfer, the key point is that due to the influence of network physical conditions, traditional FTP, mail, and instant messaging tools will have high latency, high packet loss rate, and insecure data transfer stability and file transfer quality. If modern enterprises want to make a global layout, they must face the problem of the cross-border file transfer. In view of the above problems, we analyze the solution of cross-border file transfer with Raysync. The obstacles of the cross-border file transfer: 1. Speed Due to the influence of network physical conditions, the high latency and high packet loss rate of transnational WAN seriously affect the stability of data transfer. Especially in the face of increasing data volume, it aggravates the slow transfer speed and low transfer efficiency caused by network congestion, latency, and packet loss, but ordinary enterprises often do not have this technical solution ability. 2. Security There are certain security risks in cross-border transfer tools and transfer processes. For example, FTP, a free file transfer tool, in not encrypted, and FTP script and batch files keep user ID and password publicly, which is vulnerable to hacker attacks. In the process of transfer, the hard disk transfer is at risk of damage and loss, while the non-compliant file transfer software has an unsafe connection, so it is easy to leak and steal the transmitted data in the process of data transfer. 3. Cost In order to obtain professional technical support and high-quality and reliable service, some large enterprises will choose international special lines provided by telecom operators or secondary operators. However, this method is not only long in the application period, but also extremely expensive, which is unbearable for SMEs. More importantly, international private lines also have congestion problems during international time, and their transfer performance will still be greatly affected by high concurrency. If you want to make a global layout, how can modern enterprises solve the problem of GB or even TB file data and provide it to overseas customers and global branches efficiently and stably? 1. Solve the technical problems from the root Transport layer protocols TCP and UDP, UDP has a great advantage in speed. Based on UDP transfer performance, Raysync high-speed transfer protocol independently developed by Raysync breaks through the defects of traditional FTP and HTTP transfer, and the transfer rate is increased by 100X and the bandwidth utilization rate is increased to 96%. Intelligently accelerate the transfer in the whole process, avoid the high packet loss rate caused by network latency, greatly accelerate the efficiency of file outgoing, and the multi-dimensional transfer mode meets the extremely fast transfer requirements of TB-level large files and massive small files. 2. Bank standard encryption protection Raysync is based on SSL encryption transfer protocol, adopts AES-256 encryption technology of international top financial level, and has built-in CVE vulnerability scanning, which adds multiple defense walls for data information, effectively resists external attacks, ensures the privacy of the transfer process, and ensures the integrity and safety of file data transfer. 3. The file verification mechanism is stable Breakpoint resume and automatic retransmission mechanism are adopted in the whole process, and multiple file verification mechanisms are built in to ensure the integrity and accuracy of transfer results and ensure stable and reliable transfer efficiency in ultra-remote and weak network environment. 4. Clarify the demand control costs Only when the capital investment is directly proportional to the functional requirements can the input cost be maximized. For the file transfer requirements such as single large file transfer, transnational file transfer, massive small file transfer, P2P accelerated transfer, object storage solution, or the functional requirements such as file accelerated transfer, file outgoing, file management, etc., a set of mature solutions for Raysync has three matching schemes. For enterprises and teams, it is an effective way to control costs. In response to the upstream and downstream integration of business and accelerating the globalization of enterprises, the one-stop file transfer solution provided by Raysync can drive the high-speed transfer of global data and enable enterprises to respond quickly in the fierce industry competition.

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.
