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. Six foundations of file security transfer: As an excellent service provider of large file transfer, Raysync has provided mature file transfer solutions for 2W+ enterprises in 11 fields, such as finance, internet, life sciences, and film and television production.

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.

High-speed file transfer is a broad and complex subject. Not all file transfer software programs are the same. Fundamentally, all file transfer programs help transfer information between systems. Certain frameworks or methods excel in high-speed file transfer. File transfer software uses direct device-to-device technology to achieve very high transfer speeds. Many variables affect file transfer time: Internet speed, computer specifications, data packet loss, and distance, etc., will affect the total time required to transfer data. The most important bottleneck in file transfer software today is not necessarily a network problem, but a design problem. Most file transfer applications rely on a central server to facilitate the transfer. The file is copied to the central server. After a long upload period, the receiver will download them. The intermediate step of saving the file before the transfer occurs on the receiving party accounts for an average of 50% of the total transfer time. By combining separate upload and download steps related to file transfer, file transfer software has been able to redefine "high-speed file transfer." It is an excellent alternative to other file transfer solutions and email. In the cloud storage-based file transfer example, the upload and download steps are a single task, which may cause a total file-sharing time to increase by 2 times. In the email solution, not only the upload and download dilemma reappears, but the file attachment size is usually limited. A popular way to avoid the maximum file size limit is to split the file into many smaller files. For example, you can bypass file restrictions by splitting the document into smaller chunks and sending them one by one. However, this strategy does not apply to all file types. Some file types, such as MP4, MP3, and JPG, will not break up so easily. For files that cannot be divided, use third-party compression tools. Compression should be a simple process that adds another complex step. Not only must the sender compress the file, but the receiver must also decompress the received file. Obviously, the cumbersome degree of file transfer is for the central server to facilitate the file transfer. Recognizing the obstacles that people are experiencing to facilitate high-speed file transfers, file transfer software allows users to transfer files without having to do with cloud-based mechanisms, email-based file transfers, and the intervening All content related low transfer speed. Raysync is committed to meeting the data transmission needs of the enterprise or with external partners, providing efficient and controllable accelerated transmission of large files, ultra-long distance, transnational network data transmission, safe distribution of file assets, file management and organizational authority management, and support for local deployment And cloud services provide enterprises with safe, stable, efficient and convenient large file interactive technical support and services.

At present, the amount of file-type data in enterprises has increased sharply, and many enterprises usually use conventional methods such as email, IM tools, FTP, and network disks for file transfer. When the file capacity increases and the network environment deteriorates, the efficiency of file transmission and data exchange is low, and the security is poor. If the file is larger, usually a lower method such as express hard disk is used, which cannot meet the requirements of enterprises to obtain files in time. Seriously affect the overall operating efficiency of the enterprise. Besides, the use of the above-mentioned traditional transmission methods is too decentralized, which is not conducive to centralized management of enterprises. In the era of cloud computing, enterprises currently have more and more service nodes and storage nodes, and data flow requirements based on business processes and hybrid cloud architecture are also increasing. The lack of an effective file transfer management platform is undoubtedly a major pain point. So what transfer methods do companies generally use to transfer large files? 1. CDN Technology CDN: Content Delivery Network . By adding a new network architecture to the existing network, it is mainly composed of two parts, divided into two parts: the center and the edge. The center refers to the CDN network management center and the DNS redirection resolution center, which is responsible for global load balancing, and the equipment system is installed in the management Central computer room, edge mainly refers to remote nodes, the carrier of CDN distribution, mainly composed of Cache and load balancer. Choose to publish the content of the site to the "edge" of the network closest to the user, so that the user can obtain the desired content nearby, thereby improving the response speed of the user to the site to a certain extent. The data requirements of CDN are only independent documents or "independently replaceable" document parts. 2. Transmission Technology Based on FTP Protocol FTP ) is the abbreviation of the File Transfer Protocol. FTP allows files to be shared between hosts and is used to control the two-way transmission of files on the Internet. It is a C/S system. FTP uses different port numbers to transfer different content, and different TCP connections are established. First, use TCP to generate a virtual connection for transmitting control information, and then generate another connection for data transmission. Combined with the FTP protocol, it can use file or file , file verification, and other technologies, and can also transfer large files. FTP transfer software such as also can manage users, block or filter designated IP addresses, Port, control user upload and download speed, detailed transmission history, and log, and can also carry out an encrypted transmission of data. It has the advantage of ensuring transmission security and protecting personal privacy. 3. Transfer Files Based on Middleware Use MQ, MT, and other middleware to transfer files, with data compression, large file transfer, and breakpoint resumable transfer. The transfer of large files uses BlobMessage, which uses fileserver to transfer efficient processing. Message middleware technology has two core functions: asynchronous and decoupling. These two core functions improve the working efficiency of the application system as a whole, enhance the usability, stability, and scalability of the system, and can realize the safe and reliable transmission of large files. 4. IM Instant Messaging Technology Most of the Instant Messenger technology is based on TCP/IP and UDP for communication, while TCP/IP and UDP are communication transmission protocols based on the lower-level IP protocol. The former is through the form of a data stream, after dividing and packaging the transmitted large file data, through the virtual-circuit connection established between the machines, a continuous, two-way transmission protocol that strictly guarantees the correctness of the data is carried out, mainly Reliable transmission is achieved through mechanisms such as checksum sequence number, confirmation response, time-out retransmission, connection management, and window sliding. The latter is a connectionless transport layer protocol in the OSI reference model, which is mainly used for data that does not require data In the transmission of packets arriving in sequence, the checking and sorting of the packet transmission sequence is completed by the application layer. It provides simple and unreliable transaction-oriented transmission services. Because of its fewer control mechanisms, the delay in data transmission is small and the transmission efficiency is high. IM technology mainly combines the advantages of the two to highlight the characteristics of immediacy and accuracy of transmission, but there are still certain technical difficulties in the application of large file transmission. Through the comparative analysis of the above transmission methods and market demand, the advantages of transmission software are obtained: 1) Transmission efficiency and throughput optimization; 2) The maximum transmission speed can be set; 3) The transmission performance is proportional to the bandwidth and has nothing to do with the transmission distance, and the packet loss rate has little effect; 4) Bandwidth management function; 5) Fair sharing strategy: automatically make full use of available bandwidth resources; 6) High priority strategy: real-time dynamic allocation of priority and bandwidth; 7) Realize user and terminal authentication in a safe way; 8) Application of encryption algorithm, suitable for encryption during transmission and landing encryption; 9) Scalable management, monitoring, and control; 10) View transmission progress, performance, and bandwidth usage in real-time; 11) Detailed transmission history and log. Based on the problems and status quo that most companies are facing to transfer large files, and based on the analysis of the characteristics of the original mainstream transmission technology, the fundamental to ensure the secure transmission of large file data lies in the development of the transmission software that has the advantages described in the third party. At the same time, it can solve the current technical difficulties in transferring large files.

Transnational file transfer are becoming more and more prominent, and due to the impact of the epidemic, file transfers at home and abroad have become more and more frequent. Therefore, a fast, stable, and secure file transfer software is needed to meet the needs of transnational work. Which software can be used? Let me talk about some of the problems faced by transnational file transfer. The first is that the physical conditions of the network will affect the stability of data transmission, and data transmission will be interrupted. The second is that traditional transmission modes such as FTP have high latency, and the packet loss rate seriously affects the stability of data transmission; Finally, the security and confidentiality of data cannot be guaranteed during remote transmission. Based on the above issues, the Raysync transnational file transfer solution is committed to meeting the data transmission needs of enterprises or external partners, providing efficient and controllable accelerated transmission of large files, ultra-long distance, transnational network data transmission. How can the accelerated transmission of large files be reflected? The file transfer protocol independently developed by Raysync can transfer a hundred times faster than traditional FTP and can make full use of bandwidth resources. It can be said that bandwidth utilization is quite high, which can reduce network delay and packet loss. The impact on file transfer. Can ultra-long-distance data transmission really be achieved? The answer is yes. Compared with the transmission in the same area, transmission across provinces, the speed of ultra-long-distance transmission can also keep up. So how can the security and confidentiality of file transfer be guaranteed? Raysync uses point-to-point transmission, full TLS encryption, and AES-256 encryption, supports resumable transmission, error retransmission, and load balancing to ensure transmission stability and security.

FTP is designed as a simple mechanism, which can exchange files between computers when the new network and information security are not yet mature. In the 1970s, if you wanted to protect your server from unnecessary access, you just had to lock the computer room door. User access to data is controlled by the basic user ID and password scheme. At this time, the Internet does not exist yet, and the PC revolution will take ten years. Nowadays, the security of business file transfer has become the focus of enterprise protection, especially in computing systems, and file transfer between enterprises and even in cross-border transfer has become crucial for the development of global economy. However, the original native FTP function of TCP/IP is not designed for the file transfer requirements of modern enterprises connecting the whole world. At the same time, due to the progress of network detection technology, the proliferation of hackers, malicious software, and millions of network users, the basic security mechanism of FTP has long been unable to prevent. Risks associated with file transfer using FTP: 1. The native FTP does not encrypt data; 2. When logging in, the user name and password are transmitted in clear text and are easy to identify; 3. FTP scripts and batch files save user ID and password publicly, which is vulnerable to hacker attacks; 4.FTP is used alone, it does not meet the compliance requirements; 5. When using FTP connection, the transmitted data may be "copied" to the remote computer, and may not even reach the intended destination. This possibility will expose your data to third parties and hackers; 6. Regular FTP itself does not maintain file transfer records. Isn't it time you replaced your FTP server? It's time to make a change. First, check how FTP is applied in the enterprise. Secondly, determine how your enterprise manages and protects everyone's file transfer. Finally, determine whether your enterprise can use a secure file transfer solution software Raysync can provide you with a reference for purchase), and then evaluate the software to see how it meets your business needs.
