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.

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.

What's Shadow IT? Gartner analyst Simon Mingay wrote in a research report that Shadow IT in a broad sense includes "investment in the acquisition, development and/or operation of IT solutions outside the formal control of formal IT organizations". To put IT simply, Shadow IT refers to a department or individual who uses IT-related hardware or software without knowing the IT or security group in the organization. In reality, employees in general enterprises rely on software that has not been approved by IT departments. Business departments bypass IT departments and use applications on the cloud to complete their work efficiently and quickly. These are also called "shadow IT". Although "shadow IT" and "business value" doesn't sound directly related, using shadow IT is quite simple and direct. But when shadow IT was exposed, IT revealed many security vulnerabilities to IT departments. Enterprise employees can easily bypass the IT team's approval, but they cannot check the reliability and security of the selected application in depth. Employees unconsciously input important enterprise data into unauthorized cloud services, which makes enterprise data security a gamble directly. In fact, nearly 80% of employees in general enterprises rely on this software that has not been approved by IT departments. Faced with this situation, what should IT leaders do if they find that these unsafe applications are being used by employees or are sharing sensitive information? It's obvious that it's natural to react quickly and demand that these applications be stopped immediately and that employees who violate the company's data security regulations be punished. However, the value gained by IT leaders from the discovery of Shadow IT is equally important for future IT decisions. What is the problem with Shadow IT? If IT executives find that employees are using free file sharing applications, the next step is to find out why employees use them. For what reason do so many employees bypass FTP and other systems and secretly use these applications for file sharing? Only by breaking the root cause of Shadow IT entering the enterprise can we improve the current situation of the enterprise and truly protect the data security of the enterprise. It's easy to find out that many employees express their weakness in the processing efficiency of existing enterprise application systems. FTP is time-consuming and complex, and email is limited by attachment volume, so professional software procurement costs are high. The huge amount of data and the impatient urging of customers make them need a fast way to transfer files. Although the situation of each enterprise is different, fundamentally, the biggest reason for employees to use these file transfer software is that they can handle their work at any time and anywhere with a low cost or even zero cost. Breaking Shadow IT and Solving Enterprise Application Compliance Problems Recognizing the above problems, we will find that it is not enough to order employees to stop using unsafe file sharing applications. No matter how hard IT leaders try to control the organization's data, employees can choose unsafe solutions. Enterprises can choose compliance solutions such as Raysync.

When making video content in 2020, people not only pay attention to the content quality but also pursue the best video experience. In view of this, when making a video plan, the film and television production team needs to determine the size of the created video files and how to quickly transmit them to the team and audience. The purpose of this article is to provide the creators of the media industry with new expanding information. We will analyze the reasons for the continuous growth of video file size and the available solutions to manage this growth without losing video quality and data. Film Length When creating a storyboard for video content, one of the first things to consider is the length of the video file. As this is the framework of the content, it plays an important role in determining the file size. Obviously, the shorter the duration, the smaller the video size can be estimated. Video Resolution Before shooting begins, we need to obtain specific tools to make the content reach the desired quality level, so we may need to buy specific cameras, editing tools and transfer software. At the same time, video quality will ultimately affect the size of your video file through pixels. The higher the video quality, the more pixels that make up the image and the larger the file size. Larger files will make it more difficult to transfer files. At this time, it is particularly important to have available tools to provide you with multiple resolution options. Raysync large file transfer solution can work without limiting video material flow, and has quality assurance for large file transfer and transnational file transfer. Video Format Video format has two important components: codec and container. Codec refers to the process of how to compress files, and container refers to how to save video files together and display the files by the types of file extensions . In format conversion, a two-hour 8K video is produced most often, and the file must be compressed to output it as a smaller video file. In the process of compressing large video files, the possibility of data loss is very high. High-quality compression solution is very beneficial to protect video quality and shorten the time of high-speed file transfer. Video Frame Rate A quick way to know the video size in use is to know the frames per second . The higher the FPS, the better the video quality. Whether it is a film and television production company or a start-up team, a team is always needed to make video files. There are three factors that you need to know about how to transfer such large files quickly between teams. - Distance: your data transfer distance - Delay: refers to the delay in transmitting or processing data - Bandwidth: the maximum transfer rate of a network or Internet connection, and how much can be transferred in a specific time The fact is, our technology and life are constantly improving, and the image resolution will continue to improve. Because it is a trend and a product of the progress of the times, we need to create new tools to accommodate oversized video files. Raysync provides efficient and safe large file transfer solutions to solve the problem of large file transfer for media industry workers.

The circulation of data has made some progress at the government level, especially since the 21st century, with the help of the power of science and technology, the collected data are more abundant, and the analysis based on these data can help decision-makers make more scientific decisions. For example, the city's mobile phone signaling data can accurately reflect the traffic congestion in each section of the city, and the traffic management department can optimize the traffic route accordingly. Data can help government departments make scientific decisions in advance and provide more convenient and comfortable services for residents. However, these big data managed by the government are heterogeneous, multi-source, massive, dynamic, and isolated, which also makes government agencies face severe challenges. Raysync simplifies the tedious IT management process for the government, and at the same time, ensures the security and controllability of documents. Ensure the security of data during sharing: Raysync adopts AES-256 and SSL encryption algorithms which are standard in the industry to ensure the security of confidential files, policies, and other key information documents; without fear of packet loss and latency, even the remote confidential cooperation of government departments and unreliable location information transmission can be safely and reliably completed.
