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 P2P transfer is now widely used to share files by many enterprises in their work after LAN, FTP, and HTTP are outdated.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. Compared to the traditional P2P transfer method, Raysync saves your time spend on manually file reception. The auto file reception can be realized with one click to enable the “Allow to receive transfer files from partners” button. A data asset is strictly monitored The admin user can monitor every single task in the admin console. Enter Raysync admin console – peer-to-peer transfer, you could view the peer-to-peer transfer account, IP, task name, receiver ID, country, states, city, total file transmission quantity, and transmission speed. In the meantime, it supports viewing the details of the peer-to-peer transfer task being transmitted and stopping the operation, and supports one-click viewing and downloading for historical transfer tasks. All files and individuals traceable, each P2P task can be controlled by the admin. The comprehensive upgrade made by Raysync on P2P transfer overcomes the drawbacks of file and user management, enables peer-to-peer transfer to better meet the enterprise needs, and helps enterprises manage data more efficiently. Bank-level data security Based on the needs of customers in industries such as film and media, IT Internet, Raysync adopts AES-256+TLS encryption technology between client and server to guarantee end-to-end data security. Aiming at the port problem, Raysync only needs to expose one port, which can meet all users' access needs and greatly reduce the risk of firewall port exposure; Hash verification protection is carried out at the transfer message level, file block, and the whole file to ensure the integrity of the transfer content. The optimization made by Raysync on peer-to-peer transfer, which has outstanding performance in performance, reliability, and security. The upgraded management design meets the needs of modern enterprises.

Enterprises usually meet the needs of file transfer, how to transfer files? The solution can make the four most common file transfer types, each of which has a more efficient and safer method. There are four different scenarios for file transfers in an enterprise. Let us learn more about them and file transfer applications. Large file transfer Flowing data, a five-part file transfer series focuses on key issues, such as security and efficiency, and how large file transfer solutions can help companies solve these problems. The following four application scenarios, understanding the large file transfer application is actually a good solution. Enterprises usually encounter four types of file transfer scenarios. You can see which of the following happens in the enterprise! 1. Temporary file transfer These are user-initiated file transfers. For example, after discussions with overseas partners, business users may need to send large files to keep the project running. Many companies find that this type of temporary collaboration is increasing, so file transfers are also increasing. 2. Regular file transfer These file transfers occur repeatedly. For example, you may need to send daily transaction records from a distributed location to the headquarters, or you may need to back up log files once a day. 3. File transfer between people With this type of file transfer, a single sender transfers the file to a specific individual. View the files in the specified directory by deploying a radium speed server to set up a specified account. 4. Server-to-server file transfer In this case, the file transmission is initiated by the process and is automatically received by another process to achieve the function of file synchronization. When exploring large file transfer solutions, how to improve the efficiency of transferring large files is an important consideration. However, this is not all. After all, it is the key to solve the problems encountered by enterprises in different application scenarios for transferring large files.

As with some other file transfer software, it takes a few steps to install Raysync including download the installation package, unzip, launch and activate it in three minutes, and then you can easily access the client. Then how to ensure the installation security so that to comprehensively protect the data security? Raysync focus on 5 details: - There is no built-in user name and password in the system, and the admin administrator password is randomly generated during the installation process, and it is forced to change the password when the administrator logs in for the first time. - The default restriction of the files that the user uploads are 660. Remove the execution attribute of the file and prevent the input file execution behavior. - Run the Raysync server with a low-privilege user. - Administrators can customize file suffixes that users can upload and prohibit users from uploading dangerous files. - The user rights of other groups of server program files are all closed to prevent other users from accessing abnormally. As a one-stop solution provider, Raysync has independently developed its core transfer technology with its professional technical teams to offer high-performance, secure, and reliable large file transfer and file management services for major enterprises.

In the Internet age, data transfer and file synchronization are the basic tasks of daily business development of enterprises. And with more and more branches of enterprises, the amount of data is getting larger and larger, and problems such as the loss and leakage of enterprise core data in the process of file transfer and synchronization begin to stand out. How to make the files of each branch transfer quickly and synchronize the files between multiple servers and multiple data centers is a problem that enterprises need to pay attention to. At present, there are many software tools for file transfer and synchronization on the market, but there may be some problems: 1. Unsecure Some software may be constrained by the network environment, the distance of transmission or synchronization, etc. Files are easy to be lost and damaged during transfer or synchronization, and data loss will cause a serious blow to enterprises. 2. Troublesome Many software or tools have a single function and only support one-to-one file data synchronization or transfer application mode. Or the deployment process is complicated, and manual troubleshooting is needed after errors, which wastes time and labor cost. 3. Unreliable When millions of small files are synchronized or transmitted, packet loss may occur, resulting in incomplete and inaccurate transmitted or synchronized files. Raysync is definitely the best assistance of file transfer and file sychronization. First of all, Raysync can guarantee data security, and the bank standard AES-256 encryption ensures the data transfer compliance and security. Secondly, the Raysync self-developed transfer protocol can increase the transfer speed by 100 times in one second. Moreover, the enhanced file synchronization function of Raysync has established a data synchronization solution that meets the business scenarios of enterprise users through the core technologies independently developed such as high-speed engine technology and high-speed transfer protocol technology.

The Raysync under Yunyu Technology provides high-performance, stable, and safe data transfer services for IT, film and television, biological genes, manufacturing, and many other industries. At present, 2W+ enterprises adopt the big data transfer scheme provided by Raysync to solve the data interaction problems faced by enterprises. This time, a well-known film and television production company in Shanghai cooperated with the Raysync team. For the film and television production industry, post-editing is the process of re-creation, and its importance is equal to that of pre-shooting. TV series, movies, and so on all need to cut out story clues and plots from massive film and television materials, and also need to add animation, sound effects, flowers, and the other rendering atmosphere to strengthen emotions and enhance the visibility of works. In the post-production process, the flow of video materials runs through the whole business process. In addition to excellent non-editing software and non-editing workstations, enterprises also need to deploy a set of high-efficiency and high-stability transfer software to ensure the transfer quality of massive materials and ensure the successful completion of film production. Project Difficulties The company is headquartered in Shanghai and needs to exchange materials with the team in Japan. Due to the extensive use of CG visual effects, VR shooting, 3D technology, etc., the film and television material files are getting larger and larger, with dozens of GB and hundreds of TB at every turn, and the transfer frequency is high, which requires to transfer almost every day. In addition, the company also has certain requirements for the timeliness of material transfer. Before using Raysync, the company mainly used FTP and other traditional methods to transfer files, which often took two or three days to complete the transfer of a 10GB material, which seriously affected the production progress. 1. A film may be shot in many places, and the changeable shooting location means that the transfer distance of materials is also changeable, including remote transfer, transnational transfer, intercontinental transfer, uploading, downloading, sharing, and other operations. The transfer scene is complex, with a large number and large capacity of transmitted materials, and the material flow is extremely slow. Such a complex transfer scene leads to the extremely unsmooth business process of the film and television production company, and the production progress is seriously lagging behind. 2. As mentioned above, the shooting location is changeable, which also means that the network conditions of the shooting location are uncontrollable. If the materials are transmitted in remote areas with difficult conditions or deserts, the uploading and downloading of videos will sometimes be interrupted due to the poor network environment, and the team sometimes has to arrange special personnel to monitor the data transfer. Even so, there will often be material damage, video mosaic, etc., and the producer's efforts will be burned. Unsafe transfer methods may also lead to the loss and theft of materials during the process of transfer. The content of the film and television industry is paramount, and the confidentiality of the data is very high. The material in the transfer process is maliciously stolen, which may eventually cause the copyright of the film to be infringed. 3. Production teams are scattered all over the world, and the whole team needs close cooperation to ensure the efficient completion of tasks. When the production team is in different places and across countries, the transfer of massive film and television materials becomes a problem. With the popularization of high-definition 4K and 8K, the material capacity of the film and television industry is also increasing. Traditional network transfer methods such as FTP are difficult to ensure the efficiency of large file transfer, which seriously affects the production cycle. This method has been gradually abandoned by film and television organizations. For the needs and pain points of the film and television post-team, Raysync has launched a data transfer solution for the film and television industry. Raysync is based on UDP transfer protocol, which overcomes the bottleneck of traditional data transfer software , provides the highest transfer speed, perfect integration, and control functions for the film and television industry, and brings real high-performance data transfer experience for the film and television industry. The Solutions of Raysync Raysync has a deep insight into the pain points of the film and television industry, helping customers install and deploy the Raysync server in Shanghai. Japanese team members can log in to Raysync through IP address+port number, and easily upload and download film and television materials. Comparison of the transfer data before and after using Raysync: The company used FTP transfer before. After comparison, the transfer speed has been significantly improved after using Raysync, and the upload and download speed has exceeded 90% of FTP; Raysync shortens the transfer time of video materials to the greatest extent. It takes 192 minutes and 39 seconds to transfer 10GB files from Shanghai to Japan by FTP, while it takes only 12 minutes and 42 seconds to transfer by Raysync. Raysync saves the team at least 93% of the transfer time. The Raysync also brings the following conveniences to the film and television team: Complete team and authority control In the traditional FTP solution, the folder structure and permission control are relatively simple, and Raysync provides more detailed, scientific, and complete file and personnel management functions, which meets the multi-line and complex work requirements of the film and television industry. Supports automatic management of the transfer tasks Through Raysync Client, film and television workers can conveniently monitor the transfer of material, uploading and downloading tasks, obtain information such as transfer progress, speed, and status, and can pause, renew and cancel the transfer tasks. Supports the switching of Chinese and English The film and television teams are scattered all over the world, and the Raysync switching function between Chinese and English perfectly overcomes the language barrier of transnational transfer, and the global data transfer is unimpeded. The Features of Raysync Optimize the transfer performance, and transfer video materials efficiently When the network environment is very poor, the transfer is often interrupted due to network failures, sudden power outages, etc. The Raysync breakpoint resume function ensures that the remaining materials can be downloaded from the recording position after the system is started again, with a packet loss rate of 0.00%. Fast file transfer shortens the production cycle Through the optimization of Raysync protocol and automatic compression and packaging, the network bandwidth resources can be utilized and saved to the maximum extent, and the data transfer experience can be provided for enterprise users. The transfer speed of video backhaul can reach more than 100 times that of traditional means, which greatly shortens the time consumption of video material transfer. Enterprise-level security to avoid copyright infringement Raysync has many data encryption schemes, which form an encryption tunnel between the sending and receiving ends of data to ensure that the material files will not be stolen or leaked during the video return process, so as to avoid the infringement of film copyright. Flexible and efficient business management Raysync completely records the complete behavior logs of users such as login, logout, upload, download, and link sharing, and auditors can regularly audit the operation behaviors of members, so as to guard against the occurrence of malicious data leakage.
