Cross-border large 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.

The 21st century is an era of rapid development of data and information. Mobile Internet, Internet of Things, social networks, e-commerce and so on have greatly expanded the boundaries and application scope of the Internet. Various data are expanding rapidly, and the whole society has entered the era of big data. However, big data is a double-edged sword. While the country and enterprises vigorously promote the innovative application and benefit of big data, criminals and the "black industry chain" are also stealing and selling information wantonly on the road of data transfer. "Streaking" of Core Information in Big Data Environment Data and information contain the great value, and criminals are pervasive, collecting and selling all kinds of data and information, which leads to the disclosure of personal privacy, enterprise core data, and even state secrets on the Internet. As the basis of data interaction, data transfer and file transfer are the hardest-hit areas of data leakage. Common data transfer risk sources are as follows: 1. The safety risk coefficient of the big data transfer process is high; 2. The management of enterprise data transfer is not strict; 3. The encryption link is too weak; 4. The file transfer tool used is unsafe.

In the first half of 2022 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 file 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? How can improve file sharing efficiency? 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 high-speed large 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.

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.

Many organizations rely on transferring large files from the field or between international offices. Operating through Internet links poses challenges to many standard applications: their performance is poor and transfer may fail. A common example cited by accelerated file transfer application vendors is the file transfer protocol, also known as FTP. Of course, FTP will encounter problems when running on poor quality networks, which have high error rates or long latency related to international and satellite links. In order to improve the efficiency of file transfer, AFT suppliers provide their own applications instead of FTP, thus forcing customers to adopt this AFT technology and integrate it into their existing workflow. Whether FTP or any other application using the basic TCP protocol, the problem is not the application, but the network. FTP can really perform well through high-quality links, so why replace applications to solve network problems? The key to fast file transfer is enough bandwidth and error-free connection. Raysync transfer protocol has been independently developed by Raysync, which is dedicated to meeting the data transfer needs of internal or external partners of enterprises, providing efficient and controllable accelerated transfer of large files, ultra-long-distance, transnational network data transfer, safe outgoing of file assets, file management and organization authority management, supporting local deployment and cloud services, and providing enterprises with safe, stable, efficient and convenient technical support and services for large file interaction. 1. Fast speed The transfer speed is hundreds of times faster than FTP and HTTP, which runs full of bandwidth to the maximum extent and does not affect other network traffic. 2. High efficiency Mass high-speed file transfer softwares is 6000 times faster than FileZilla in the same network environment. 3. Transfer is unlimited Cross-regional and transnational big data replication, migration or archiving can transfer at least 100TB of data every day. Raysync provides self-controllable, secure, and private multi-industry data transfer solutions, and helps customers build information channels and integrate data resources.

Data transfer has played an important role for enterprises to conduct business with its customers, partners and suppliers while acting as its foundation in mining data value. However, the emergence of the Big Data era has spawned a massive amount of data, while various data types and interactive scenarios have become increasingly complex, the efficiency and security of data transfer is also facing its challenges. If enterprises desire to continue extract value and create opportunities, the foremost priority is to tackle data transfer. Challenges: Large File Transfer ● While the amount of data has skyrocketed, the transfer efficiency is still poor; ● Data types are diverse and traditional transferring methods are difficult to guarantee its integrity; ● Network environment is complex while the cases of data loss and leakage are increasing; ● Cross-regional and long-distance teamwork has increased, but high latency and high packet loss rate have also become prominent. The key to solving the challenges above is to find a first-class data transfer engine. This would eminently support enterprises to build a high-speed, secure, and stable environment for data transfer, which brings an edge to lead in a data-driven development. The Great TCP Bottleneck Transfer protocol is the foundation beneath every data transfer, in which TCP is the most commonly used IP transport layer protocol. Compared to other protocols, TCP is able to provide a more reliable service for establishing connections between specific network systems and applications. Originally developed in the early 1970s when networks were still local and data files were small, TCP served as the basic protocol which enabled data to move efficiently and reliably within the local area network with very small bandwidth. To maintain this reliability, TCP ensures that the application data transmitted in a single TCP connection arrives at the receiver’s application in the same sequence as when it was sent. Therefore, TCP uses an algorithm to establish the connection between the sender and receiver, creating transfer requests in turn, and splitting the data into packets, which are then sent separately through the network without the need for acknowledgement until reaching its definition limit. . The sliding window protocol is used by TCP to define the data buffer. Figure 1 below is a simplified diagram that demonstrates how TCP sends out small packets over the network and how TCP windowing controls how much data can be transmitted without acknowledgement. As the packets are delayed, TCP will then slow down the transfer rate with a smaller window size, which further limits the number of unacknowledged packets allowed. TCP algorithm is proved to be effective when data transfer occurs over a short distance while the network is not congested. However, when the round trip time of packet transfer is inevitably increased by distance, both the performance and efficiency shall be affected. Especially under the scenarios of long-distance, transnational transfer, the transfer of large files and massive small files will expose the drawbacks of TCP protocol: ● Low transfer efficiency, end-to-end transfer requires sequence acknowledgement, the data processing is slow; ● Increase of data loss rate and latency when large files are transmitted; ● Extreme congestion control throttling which results in unnatural throughput loss; ● TCP cannot guarantee its reliability, its file check mechanism is imperfect. In essence, TCP cannot be defined as a reliable transfer in the true sense of the word. Especially under the pressure of data volume and distant transfer, TCP is unable to guarantee the efficiency of transfer and yet it may expose enterprises to data security threats. Raysync – A Brand New Transfer Protocol Raysync’s high-speed transfer protocol is a core transfer technology developed by Shenzhen Yunyu Technology Co., Ltd. based on the UDP transfer protocol. This breakthrough technology does not simply optimize or accelerate data transfer but it takes a leap forward in the transfer technology to completely eliminate the underlying bottleneck while overcoming the limitations of traditional network and hardware. Raysync is able to fully make use of network bandwidth thus provides an ultra-low latency, high speed and end-to-end output service. The transmission rate can be increased by nearly 100 times, achieving over 96% of bandwidth utilization rate while easily adhering to the security, controllability and stability requirements for TB-level large files and massive small files transfer. Transport Layer: A Black Tech that Overthrows the TCP Protocol The TCP transfer protocol does provide a reliable data transfer under ideal conditions, but with its fixed throughput bottleneck, a prominent and serious condition would occur due to high packet loss and latency caused by a long-distance network transfer. Raysync guarantees reliability in the application layer with an innovative method that eliminates drawbacks such as low efficiency in TCP, packet loss, processing errors and unstable transfer rate. To ensure 100% reliability, Raysync adopts the best mechanism that accurately identifies and passes on the actual packet loss condition on the transfer channel. Application Layer: Best Alternative to FTP The FTP transfer protocol has been used for more than 40 years, but it is also a fact that the efficiency of FTP file transfer has been far less than the growth rate of data in the face of today's complex file exchange requirements. FTP is even worse in the file management tasks that enterprises urgently need today. In order to transfer files while maintaining security through FTP, this requires complex scripts, continuous maintenance, and even other applications to assist. All of which may cause time and money losses to enterprises by varying degrees.
