In today's digital age, data synchronization and transfer are a common need in all fields. Whether it is data synchronization within an enterprise or storing and sharing data in the cloud, efficient file processing is required to achieve high-speed Synchronization transfer. And to meet the growing demand for data processing, people continue to explore and optimize various file processing strategies. In the past, when faced with large file transfers, slow and inefficient transfer speeds were often encountered. To address these challenges, researchers and engineers have proposed a variety of file processing methods aimed at improving the speed and efficiency of file transfer. Raysync File Processing Relying on High-Speed Transfer Engine Relying on the technical advantages of its high-speed transfer engine, Raysync can effectively solve the problems of delay and data loss caused by traditional TCP transfer, thus improving the efficiency and stability of data transfer. At the same time, Raysync’s data synchronization has a variety of file processing methods. It enables enterprises to apply it to various scenarios and meet their different data processing needs. Preserve file modification time Raysync default file verification mechanism: Keeps the modification time of the file transferred to the target the same as the modification time of the source file, ensuring the integrity of the file. Enabled by default. Only transfer files and folders under the source directory Scenario: Maintain the same directory hierarchy between the source and target. It is suitable for the case that there is already some file data in the target, or you don't want to create a new folder path.  Automatically delete the target file when the source deleted After the synchronization is completed, if the source file is deleted, the same file will be automatically deleted at the target. If this option is activated for two-way synchronization, if the file at either end is deleted, the file at the other end will be deleted as well. Scenario: Keeps the completion of files on the destination and source side the same, and at the same time will delete files/folders on the destination side that are redundant compared to the source side. Example: Synchronize all the files in directory A to the files in directory B, and delete all the redundant files in directory B, so that the files in both directory A and directory B are guaranteed to be consistent. Automatically delete the source file every file done Scenarios: 1) File Migration: Automatically deletes source files that have already been migrated. Avoid manual deletion. 2) The source directory will only add new files with different names. It can realize automatic deletion of the files that have been successfully transferred from the source after each synchronized transfer is completed without additional operation, which can save storage space at the source and reduce the time and traffic of traversing the files at the source during the second transfer. There are two ways of deletion: 1) Delete all files and folders inside the source 2) Delete only the source files and keep the completion structure of the directory. Processing methods when the target file already exists 1) Overwrite 2) Overwrite if the source newer Scenario: update only when the source file is newer than the target file. Ensure that the target files are up-to-date and save transfer traffic by reducing unwanted synchronization. Better suited for two-way synchronization. 3) Append to the target file Scenario: suitable for the file new data will only be written to the back of the case, and can be treated as a kind of incremental synchronization . If the source has made changes to the previous content, this mode will not synchronize the data that has already been transferred. For example, the log file generated by the program, under normal circumstances, the log will only write to the back, there is no modification of the previous log content. Test: txt text is more appropriate. Word documents will damage the file. 4) Rename Conclusion To sum up, Raysync's multiple file processing with multiple text file synchronization provides businesses with the convenience of data processing. If you are looking for a powerful, fast and stable file synchronization tool with good security, Raysync is undoubtedly a choice worth considering.

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.

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. Basing upon UDP’s high-speed transfer protocol, Raysync breaks through the bottleneck of large file transfer which satisfy enterprises’ needs by building an intelligent transfer platform that processes and integrates massive data at an unprecedented speed.

Introduction A peer-to-peer connection in telecommunications relates to a communication between two terminals or nodes. Peer-to-peer is shortened to P2P sometimes. In sharing platforms or in other data-sharing protocols between people, this use of P2P is separate from the use of P2P which means peer-to-peer. For instance, a telephone call when one phone is connected to another, and only the others could hear what one caller says. In contrast, this is a topology for point-to-multipoint or broadcast communication, where several nodes can receive information from a node. Additional instances of peer-to-peer links include leased lines, microwave relays, and two-way radio. For example, radio and television broadcasts are points-to-multiple. Have you used P2P? P2P transfer is now widely used to share files by many enterprises in their work after LAN, FTP, and HTTP are outdated. P2P transfer, known as peer-to-peer transfer, is an instant file transfer mode, which aimed to enable all clients to provide resources, including bandwidth, storage space, and computing capacity. P2P transfer technology has wide application scenarios, such as audio, video, and data sharing in various formats. How does P2P technology transfer files instantly? Why P2P transfer is accepted widely by many enterprises? In this article, let’s start with these two questions and explore the answers to peer-to-peer transfer. Everything about P2P Transfer in One Picture With the growing number of IP cores combined on one chip, the system-on-chip architecture is able to deploy complicated applications. The enormous need for communication and the ample computing capability on the chip put a considerable burden on the architecture in communication. Scalable communication architectures are therefore needed to implement future systems efficiently. Two types of communication systems, namely peer-to-peer and bus-based designs have traditionally been explored. At the expense of the specific channels between all communicating IP pairs, P2P communication designs can provide the most communication performance. However, in terms of high complexity, expense, and design effort these designs are poorly scalable. By contrast, bus systems can connect a few dozen IP cores economically and eliminate the complexity of the system and the specific cables required by P2P systems. The traditional HTTP transfer is to copy data to the client via server, thus the transfer speed is restricted by the bandwidth. Especially in today's network environment, the large amount of clients connects to one server, the bandwidth of servers will be shared, and the bandwidth of clients is difficult to be fully utilized, resulting in low efficiency of overall data transfer. In general data transfer, client A and client B is essential to build a connection to the server, and then data will be transfer through the channel built by the server and data recipient. P2P transfer technology builds the direct channel between client A and client B, shorten the original upload-download "1+1" time to 1; Secondly, "client A-server-client b" is turned to "client A-client b", which does not transit through the server and does not consume the expensive storage space of the server. Figure 1. P2P Transfer in One Picture Cons & Pros of P2P Transfer P2P technology is popular in many industries such as film and media, Internet TV, telemedicine, it not only provides freedom and facility to data transfer but also integrates all potential Internet resources. In technical expert’s opinion, P2P transfer is a kind of instant technology for quick data moving and sharing, it is beneficial to creating opportunities for enterprises in today’s market environment driven by data. However, with 5G emerging and the continuous development of information technology, P2P transfer is undoubtedly a double-blade sword, so it’s difficult for enterprises to step forward. Pros: Low cost: save the cost on the server. Efficiency improved: remove the intermediate procedures and establish simple connections. High stability: eliminate the server-centered single-point service in the past, form the decentralized P2P transfer organization, which solved the fault problem caused by the central single point. Cons: Network bandwidth resources are consumed in large quantities: The concurrent connection of P2P transfer makes the resources consumed in large quantities, it is easy to cause network congestion and reduce the performance of other applications. Inconvenient management: The P2P transfer is decentralized, the amount of users is huge thus it’s hard to take care of all users. Security risks of data leakage: The widely use of P2P transfer leads to someone use the loopholes in the system to invade user privacy and destroy data. Some criminals even add viruses in the P2P transfer process, which poses a threat to users' computer security. The P2P transfer technology is not strong enough to satisfy enterprises’ various needs, therefore, there must be a breakthrough. According to whether the clients are in the same network environment, the difficulty degree of P2P transfer technology is different. What modern technologies can be used to optimize and how to optimize? Let's continue to explore the principle of P2P technology and try to find a breakthrough. P2P technology upgrading Based on NAT+Raysync The transmission protocol of Raysync has abandoned the use of transmission messages as both byte counts and TCP protocol. With its revolutionary UDP transmission method, Raysync overcomes faults in existing TCP-based file transfer protocols . The transmission speed of FTP/HTTP is hundreds of times higher and is not reduced by the size of the file, transmit distance, or network difficulties. Raysync can offer secure internal and external sharing of data, enabling you to securely upload, download and edit files on a user-friendly interface. Send huge files via mobile devices and web browsers in every location and anywhere. Characteristics Raysync transmission protocol may make full use of a broad network of bandwidths for the fastest transfer of data. It can enable users in the huge data distribution application scenario to finish the big data transfer in the least time. The multi-channel parallel transmission feature of the link is supported by RaySync Transmission Protocol. When a client interfaces between point B and point A, a multiplicity of unrelated data streams can quickly be transferred in Parallel via the multi-parallel channel property. The transfer of these data streams does not require the handshake connection process, which considerably enhances the transmission in real-time. Raysync transmission protocol is UDP-based and may transit over various NAT devices smoothly. Here we divided into two situations for analysis: On the same network Assume that the internal network interface is 1000M, the LAN bandwidth is 10M, and the bandwidth utilization rate is 50%. Client A and Client B are in the same network environment, as shown in the following figure. If the traditional file transfer method is adopted, the A user needs to upload the file to the server first, and then B can download it from the server, there only 10M network bandwidth will be utilized in the whole transfer process. While through peer-to-point transfer, A and B can directly establish a connection, file transfer makes full use of the network bandwidth of 1000M, and the transfer efficiency can be improved by 100X. Figure 2. P2P technology on the same network Raysync combined the P2P technology with Raysync ultra-high-speed transfer protocol, the network bandwidth is fully utilized up to 96%. The file transfer process is accelerated, the TB-level big data and massive data transfer have never been easier. Figure 3. P2P technology upgrading Based on NAT+Raysync On the different network Client A and client B are in two different network environments, and they need to try to connect with the target end to judge whether they can penetrate the network to establish communication. The P2P transfer between two clients will be different according to different clients. Several common P2P transfer methods through middleware include Relaying, Connection reversal, UDP hole punching. Through the following characteristic comparison table, we can simply grasp the characteristics and application scenarios of these methods. Table 1. Characteristics and compassion table According to the methods listed above, Raysync P2P transfer will try to connect with the recipient end in priority. If it is failed to connect, it will be connected by reverse connection or UDP punching. If it is still failed to connect, then the server transfers will be adopted. Raysync will automatically select the best transfer mode in the whole process, reduce the network burden and make full use of network resources. Besides, the P2P transfer based on UDP needs to consider the type of NAT, because the penetration ways of different NAT combinations are not consistent, some can penetrate, while some cannot. Figure 4. P2P technology on the different networks Digging deep into NAT penetration technology, Raysync combines more than 10 NAT penetration technologies with Raysyncb ultra-high-speed transfer protocol and simultaneously applies on P2P transfer. In practical application, the penetration effect of these 10 NAT combinations can meet the current P2P transfer needs. Even in the face of a few impenetrable situations, Raysync may still be able to improve the transfer efficiency and find the optimal solution for P2P transfer. A More Universal P2P Transfer through Innovation on Speed and Management Transfer acceleration ensures efficiency improving In the peer-to-peer transfer, the patented Raysync ultra-high-speed transfer protocol is adopted. This protocol can eliminate the bottleneck at the bottom layer, it is immune to limitation of the traditional network and hardware, fully utilize the network bandwidth, and realize ultra-low latency, high speed, and end-to-end output service, the transfer rate is improved by nearly one hundred times, thus easily achieves the safe, controllable and stable transfer of TB-level large files and massive small files. Figure 5. P2P technology on the different networks about penetration and acceleration Comparison of the peer-to-peer transfer efficiency Test environment: Shenzhen-Beijing, network latency 35ms~45ms, packet loss rate 1% Server: Alibaba cloud Shenzhen, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk ClientA: Alibaba cloud Shenzhen, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk ClientB: Alibaba cloud Beijing, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk File transfer is automatic For team collaboration, Raysync supports automatically receive peer-to-peer files from your partners.

MFT means managed file transfer. The term MFT began to appear in the mid-2000s. In the field of file transfer, it is a brand-new method of data transfer that enterprises have begun to use, and it is clearly distinguished from "file transfer protocol" in the 1980s. As defined by Gartner, “Managed file transfer software and services enable users to manage and monitor file transfers within and between organizations.” In this definition, Gartner uses “manage” and “monitor” to highlight and explain the key differences between MFT and FTP. - Manage – means to manage all file transfers using one interface across all business units, operations, systems，applications, partners, etc. - Monitor – means to monitor all file transfers in one centralized location which in turn means better governance, compliance，and reduced IT costs. Driven by increasingly stringent privacy regulations and the need to quickly transfer and track files globally, many organizations are in the process of replacing their legacy FTP systems and moving towards MFT solutions. In fact, managed file transfer solutions are gaining the most momentum. We explain to you what does MFT means? At present, we easily find that no matter in the fields of health care, government, technology，or media，the information now will inevitably move around. In some cases, such data may have to leave the organization's security controls to enter customers or other business systems. The traditional file sharing way can comply with personal needs, for example, sending private messages or videos. But this kind of way does not comply with the enterprise needs. MFT is dedicated to creating a more secure and efficient IT environment within the enterprise. Enterprises that use MFT solutions often deal with sensitive information on a regular basis, making security the core of their business functions. Managed File Transfer, as the acronym implies, is a service that manages data and ensures its security during transfer. Enterprise organizations often use it, and it can get rid of slow and temporary methods such as FTP and HTTP. In the final analysis, a good MFT solution should simplify your transfer process and comply with security standards such as SSL encryption solution provided by Raysync). A good MFT solution should include: 1. The secure connection. 2. Encrypt data being stored or "still". 3. A reverse proxy that acts as a pass-through and does not write any unencrypted data to the server. 4. The ability to support an organization's security policies, such as password expiration or SSL.
