When companies are transferring files over long distances, when they choose traditional FTP, network disks, etc. to transfer large files, in addition to slow speed, they often encounter transmission errors, transmission interruptions, and resuming transmissions. Although the traditional FTP transfer method supports the batch transfer of folders, when the number of files is large, in addition to the very slow speed, there are often problems such as missing files, file content errors, and inconsistent file numbers. When the file capacity increases and the network environment becomes worse, the efficiency of file transfer 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 on time. Seriously affect the overall operating efficiency of the enterprise. This type of data transfer requires the use of data transfer protocols to ensure efficient and rapid transfer on high-speed networks. Several new data transfer protocols based on TCP or UDP have been introduced, and some comparative analysis and research have been carried out on such protocols. There are currently several data transfer protocols and congestion control mechanisms GridFTP, FASP, QUIC, BBR, and LEDBAT, which are potential candidates for comparison in various scenarios. These protocols are designed to make fair use of available bandwidth among competing streams and provide reduced packet loss, reduced delay, and fast data transmission. In this paper, the behavior and performance of the data transfer protocol in various scenarios are explained. These scenarios include transfers with various file sizes, multiple streams, background, and competing for traffic. The results show that FASP and GridFTP have the best performance among all protocols in most scenarios, especially for long-distance transfer with a large bandwidth-delay product . Due to the nature of its current implementation, QUIC has the lowest performance, which limits the size of the transmitted data and the bandwidth used. TCP BBR performs well in short-distance scenarios, but its performance decreases as the distance increases. The performance of LEDBAT cannot be predicted, so a complete evaluation cannot be performed. Comparing the performance of the protocol with background traffic and competing traffic shows that, except for FASP, most protocols are fair and radical. In addition, QUIC and FASP, which have the highest CPU utilization, are used to measure the resource utilization of each protocol on the sender and receiver. The performance of LEDBAT cannot be predicted, so a complete evaluation cannot be performed.

File Transfer Protocol is a protocol used to move files on the Internet. It is unique in that it uses two different connections. The control connection is used to send commands between the FTP client and the FTP server. File transfers is sent on a separate connection called a data connection. FTP packet filters can handle active and passive FTP sessions without any special client configuration. Inactive mode FTP, the FTP server establishes a data connection. In passive mode, the client establishes a connection. Generally speaking, FTP user agents use active mode, and Web user agents use passive mode. Like the FTP packet filter, the FTP proxy handles active and passive FTP sessions, but it also protects your FTP server and restricts FTP protocol commands between the client and the server. You can use an FTP proxy to: 1. Restrict the commands sent on the control channel 2. Restrict the file name or file type according to the file extension 3. Prevent buffer overflow attacks caused by abuse of the FTP protocol 4. Abnormal use of FTP commands through WatchGuard intrusion prevention service to prevent unauthorized directory traversal After adding the FTP proxy policy to the Firebox configuration, you can access the two proxy actions included in the product. You can use these rule sets without changing them, or you can use these rule sets as the basis for rule sets to meet the needs of your organization. This module shows you how to customize these two agent operations. FTP-Client This proxy operation includes a rule set that controls FTP commands launched on computers on your trusted or optional network. The FTP client application uses specific commands that the Firebox can recognize and control. Use FTP-Client operations to control the outgoing FTP traffic. FTP-Server This proxy operation includes a rule set for protecting and controlling FTP commands sent to your FTP server. Use FTP-Server operations to control incoming FTP traffic.

What are FTP ) and a complete description of SFTP and TFTP? FTP, SFTP, and TFTP are protocols used to transfer files over the network. File Transfer Protocol This is a standard protocol used to transfer files between a computer and a server over a network . FTP is a larger file used by computers to transfer files over a TCP/IP network. If someone anywhere in the world wants their file to be available, all the other person wants to download is upload the file to an FTP server. Anyone in the world can connect to the FTP server and download files using the FTP protocol. Here we use a dedicated FTP server to share files, but there is no need to set up a dedicated server for FTP because they hope that they can configure their computer to act as an FTP server. In Microsoft Windows, this can be done in the Internet Information Services Manager. There are several ways to use FTP to transfer files. Here we use a standard Internet browser or use an FTP client. For example, let's download an MP3 file uploaded by someone on an FTP server. Let's use a standard Internet browser, open a web browser type in the address FTP server, or visit a regular website if necessary. The URL of the FTP server is the ftp.example.com type address in the URL. When we visit a regular website, the prefix will be HTTP, because we are going to an FTP site, and the prefix is FTP.Now it connects to the FTP server. It is an example of viewing a web browser on an FTP server. We can browse different types of folders on the FTP server according to the available content, and download the content we need. Select MP3 on your computer and download it. Sometimes the FTP server will regain an account with a username and password, and sometimes we can log in anonymously. This depends on the type of authentication of the owner of the FTP server settings. Other connected FTP servers in the FTP client. There are many FTP client users. Perhaps the most popular free FTP client is Filezilla. The FTP client provides a graphical user interface for a better experience than using a web browser. In the web browser, the web address is the FTP server and the user and password , and the port number is 21. Press the connect button and it will connect to the FTP server. Files and folders on our computer in the left panel The files and folders in the right panel are remote FTP servers. Click from the right panel and drag from the FTP server, such as MP3 files, and then click them or drag from the left panel to your computer. If you have the proper permissions, you can upload files from our computer to the FTP server through the left-to-right panel. The file will be uploaded to the FTP server. Transferring files between computers is a commonly used file transfer protocol. Especially batch transfer of files. Another common use of FTP enables website designers to upload files to their web server. The main disadvantage of using FTP is that the insecure protocol data it transmits is not encrypted. All data sent is in plain text. Which ones can cause safety issues? FTP should indeed be used on a limited basis, or only use a trusted network or send data that is not sensitive. However, to transfer the data to be protected, a more secure protocol should be used. Secure File Transfer Protocol The secure file transfer protocol is like FTP, which adds a layer of security. The data using SFTP is encrypted using a secure shell during data transmission. No data is sent because all plaintext is encrypted. SFTP authenticates users and servers and uses port 22. Both FTP and SFTP are connection-oriented protocols. They all use TCP for file transfer, so file transfer can be guaranteed. Trivial File Transfer Protocol This is a very simple file transfer protocol. It is not used to transfer files via the Internet, such as FTP and SFTP. TFTP is mainly used to transfer files within a local area network.

File Transfer Protocol is a server that sends files over the network. Here, we will introduce the meaning of FTP, other software available, and the way FTP works in the background to ensure correct data transfer. What is File Transfer Protocol ? As a noun, FTP is a server connected to TCP/IP. In short, FTP sends files over the Internet. All well-known web browsers have basic FTP functions so that computers can work together remotely. As a verb, FTP is an act of sending files to and receiving files from users. Common forms of FTP include uploading and downloading pictures to social media, email attachments, and documents shared on chat applications. All of these have capacity limitations, but basic FTP user does not require additional software. FTP is an online space. It follows a set of established rules that act as a protocol when sending information over the Web. The browser and interface enable the FTP server to transfer files. Any operating system will have FTP functionality so that you can receive files. How the File Transfer Protocol Works? Whenever two or more devices share files, FTP will ensure that they are placed in the correct location. When you move files on the Internet, there are some protocols to ensure delivery. FTP works off-screen, allowing people to browse online page by page. Nowadays, you can build HTML and create websites without purchasing other FTP software. When someone tries to access or request a file, the local or remote server will act as the host and transfer data. FTP software enhances security Security is an issue to be considered when transferring secure files. We all know the story of the webserver hacker very well. But now, companies can use FTP software to help defend against hacker attacks and increase file capacity. FTP software improves storage and allows files such as entire directories to be sent as a whole. It is also preferred by organizations because it is a private form of the file transfer. Advantages of FTP software: Complete file sharing function; Automatically back up data; The connection fails and restores to the location where the file was transferred. When choosing FTP software, you should consider data security. Assessing risk requires understanding the functions provided by each FTP software and the sensitivity of the organization's data. Research the available options and find the right FTP for you.

What designs have been made for file storage in Raysync? What storage methods does Raysync support at present? Today we give answers to these two questions. Let's first clarify the three concepts of object storage, file storage, and block storage: Object storage: A strategy of managing and manipulating data storage as different units . These objects are stored in a separate warehouse and are not affected by files in other folders. Get each piece of data and designate it as an object. The data is stored in a separate warehouse, instead of a file in a folder, and is bound with the associated metadata and unique identifier to form a storage pool. File storage: Data is stored as a piece of information in a folder to help organize data among other data. This is also called layered storage, which imitates the storage mode of paper documents. When you need to access data, your computer system needs to know the path to find data. Block storage: Split a file into individual data blocks, and then store these blocks as separate data. Each piece of data has a different address, so there is no need to store them in a file structure. Among the above three storages, object storage adds comprehensive metadata to files, eliminates the hierarchical file structure used in file storage, and places all contents in a flat address space called a storage pool. Object storage has no archive hierarchy, and the source data is completely customizable, so compared with file or block storage, the restrictions are much less and the resources are optimized; At the same time, data can be added forever, and unlimited scalability greatly reduces the storage cost of data; Faster data retrieval and better data analysis promote the wide application of object storage. The use case of the object storage: Providing rich media: Define workflow by using industry-leading solutions to manage unstructured data. Reduce the cost of rich media distributed globally. Managing distributed content: Optimizing the value of data throughout its life cycle and providing competitive storage services. Embrace the Internet of Things : Effectively manage machine-to-machine data, support artificial intelligence and analysis, and reduce the cost and time of the design process. Storage methods supported by Raysync: As an enterprise-level large file transmission software, Raysync has provided high-performance, safe, and stable large file transmission and transmission management services for 2W+ enterprises in IT, finance, film and television, biological genes, manufacturing, and many other fields.

The new energy industry is developing rapidly. New energy electric vehicles, solar appliances, wind energy, ocean energy, biomass energy, nuclear fusion energy, etc. The development of the new energy industry is conducive to the optimization and upgrading of chemical enterprises, accelerating the development of science and technology, and emerging more and more world-class chemical enterprises. Most of these multinational chemical enterprises adopt a globally integrated management mode, distributing raw materials, R&D, production, and sales links around the world according to the advantages of different regions. All branches need to keep close contact, and transnational large file transmission plays an important role in it. However, the process of transnational large file transmission will be affected by many unknown factors, such as transmission interruption and transmission error. If the data leakage and business loss of the enterprise are caused by the imperfect file transmission mode, it will cause immeasurable losses to the enterprise. Solving the problem of transnational large file transmission and ensuring the efficient, safe, and complete transmission of data to the destination is the top priority of business development. 1.
