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 P2P transfer is now widely used to share files by many enterprises in their work after LAN, FTP, and HTTP are outdated.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. As a one-stop solution provider for large file transfer, Raysync can be used as a tool for enterprises to realize fast file cooperation, and can also be used as an enterprise data management platform to provide data transfer services for industries such as film and media, finance, IT Internet, etc.

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.

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. Accelerate inter-departmental cooperation to fully share the data of government agencies: support the rapid transmission of information across regions, and easily realize inter-departmental and inter-organizational cooperation. Make data easy to manage: government agencies have a large number of departments and users, and Raysync provides user management functions for management to realize hierarchical authority restrictions. A single user interface simplifies the transfer process between departments and various organizations.

How to transfer large files quickly? It has become a problem that people must understand in work and life. There are many ways to transfer large files. You can refer to the methods of the large file transfer: In fact, in the Internet age, speed has determined efficiency. In the production process of the enterprise, information and data exchange and transportation are required. At this time, a large file transfer is required. Many industries need to transfer large files. For example, the film and television industry needs to transmit video materials every day. A video as small as tens of megabytes and as many as several terabytes of video data must be transmitted from the shooting location to the video center for editing and rendering. For example, the meteorological observation points in the meteorological industry need to conduct real-time weather observations, and the data can be summarized to the Meteorological Bureau in real-time to issue accurate and correct weather forecasts. For example, Internet technology companies and big data analysis companies need to receive various data materials from various industries. For example, large enterprises need to transmit the financial data of each branch to the headquarters for summary at the beginning of each month. At this time, in the face of such a huge amount of data, how can companies ensure the safety, stability, and efficiency of large file transfer, then large file transfer software is indispensable for enterprises. For now, there are many file transfer software on the market. A peer to peer transfer is still very convenient, but there is a limit to the file size, and the speed is sometimes slow depending on the network environment. But it is also a good choice for individual users to transfer small files. The transfer of large files using FileZilla, network disk, etc. is relatively stable and can support resumable transfers, but the speed will become slow when transferring large files, and the data packet loss rate is large, the transfer reliability is poor, and the speed is particularly low during international transfer. obvious. If you use a network disk, it will be inconvenient to operate, and you need to upload the file to the terminal before downloading it. Besides, there is another way for large files, which is to send a large number of files to the destination. However, unpredictable problems such as damage to the hard disk and delays in express delivery may occur during the transportation, and the real-time performance cannot be achieved. , Which limits the efficiency to a certain extent. If it is an enterprise-level large file transfer, you can choose to use the Raysync software. Raysync is an enterprise-level transfer product for enterprise large file transfer, adhering to the purpose of faster, more dazzling, more stable, and more powerful. The file transfer is very good. Large files can be transferred to the destination reliably and quickly, and it is also very good in the international transfer. Raysync High-speed FTP solution has the following advantages: 1. This transfer software supports one-to-one, one-to-many, and many-to-one transfer, and it can flexibly solve the problem of large file transfer by mixing multiple transfer modes; 2. The transfer data is reliable, the transfer layer adopts multi-layer channel encryption technology for the transmitted data, and the data security is guaranteed; 3. Support for resumable transfer even if the transfer is interrupted; 4. Make full use of the bandwidth to maximize the transfer speed. According to actual test results, the transfer speed of large files can be increased by more than 100 times, and the maximum speed of a single connection can support 1Gbps; 5. Speed determines efficiency, time determines money. Now big data is very important to enterprises. Huge data must be transferred quickly to hold the information in the hands of enterprises in real-time. Realizing the rapid transfer of large files can improve work efficiency.

In the Internet age, big data movement is an inevitable problem faced by enterprises. You can choose traditional FTP, network disk, and other methods to transmit, which may be advantageous for small files. But for large file data, transmission speed trouble may appear. The slowness and unreliable data greatly affect the work efficiency of enterprises. The transnational transfer is even worse. The traditional network transmission method is extremely slow and has a large packet loss rate. After the transfer is interrupted, it needs to be retransmitted. It is extremely unstable in terms of data reliability and transmission speed. The time cost of using the hard disk delivery method is too large, which is unacceptable for efficiency-conscious companies. Therefore, the birth of transferring software effectively solves the problem of large file transfer for many enterprises! The main advantages of large file transfer software are as follows: 1. The transmission data is reliable, and the transmitted data is multi-layered at the transfer level to ensure the consistency of the transfer data; 2. Support interrupted resumable transmission, even if the transfer process is interrupted, it can resume seamlessly; 3. In terms of transfer speed, even cross-border long-distance transmission can maximize the use of bandwidth and maximize the transmission speed. According to actual test results, the transmission speed of big data can be increased by more than 100 times, and the maximum speed of a single connection can support 1Gbps; 4. The multi-channel design of the transfer protocol can save the transmission delay caused by the TCP three-way handshake to establish a connection when the user transmits data, and the real-time performance can be increased by up to 1 times; 5. The transfer performance is proportional to the bandwidth and has nothing to do with the transmission distance, and the packet loss rate has little impact; 6. Data security adopts encryption algorithm, and both the transmission process and data landing are encrypted; 7. Open multi-terminal SDK, easy and quick integration, etc. These are the advantages of large file transfers. I think each method has merits and the key lies in your transfer needs. Properly evaluate the needs of the transfer in order to choose the most efficient large file transfer solution.
