In the process of file transfer, TCP and UDP are transport layer protocols, and their communication mechanisms are different from the application scenarios. The version V22.214.171.124 of Raysync supports the setting of transfer protocol in 4. In order to better answer the question of how users choose file transfer protocol, the following contents make an easy-to-understand short answer to file transfer protocol: - Automatically select UDP/TCP: it will automatically switch to the TCP mode when the transfer latency is less than the value you configured. - Only UDP - Only TCP - Default: The UDP mode will be used in priority, it'll automatically switch to TCP mode when the process of transfer is interrupted. Why are there four transfer protocols? First of all, we should understand the meanings and differences between these transfer protocols: The basic difference between TCP and UDP: TCP refers to the Transmission Control Protocol, and UDP means the User Datagram Protocol. Both of them are the protocol of the transport layer, but they have different mechanisms. - Message mode: TCP designed for the connection-oriented streaming mode, while UDP for connectionless datagram mode. - TCP provides reliable services, and UDP may lose packets. - TCP has the strict requirement of system resources, while UDP not. - TCP transfer efficiency is slow, UDP has good real-time performance, and its work efficiency is higher than TCP. - Each TCP connection can only be point-to-point, while UDP supports one-to-one, one-to-many, many-to-one and many interactive communication. The scenarios of TCP and UDP: In conclusion: TCP is a kind of reliable transfer method but the transfer speed is relatively slow. While UDP is relatively unreliable but has ultra high speed. Therefore, when choosing a specific file transfer protocol, it should be decided according to the requirements of communication data. If the real-time investigation of communication data is far more important than the integrity of communication data, TCP protocol is preferred; On the contrary, UDP protocol is used. The four file transfer protocols supported by Raysync are designed to facilitate users to configure flexibly according to actual transfer requirements. It is not limited to a certain transfer protocol, and is suitable for file transfer requirements of all walks of life. The ultimate purpose of file transfer software provided by Raysync is to help more enterprises realize high-speed data transfer and create value for enterprises.
The file transfer protocolserver runs a program that utilizes the file transfer protocol and allows you to upload and download files. By default, the file transfer protocol is not secure because the data it transmits is not encrypted. All file transfer protocol servers on this list include options for encrypting and protecting data by using secure protocols such as SFTP or FTP/FTPS. File transfer protocol servers are usually used to allow remote workers to upload or download files from the server. Network and system administrators also use it to back up network configuration and run updates. There are many file transfer protocol server programs available, from free software with basic functions to commercial products with advanced functions such as mobile device access. In this article, I will share the best file transfer protocol server for Windows. 1. FileZilla Server FileZilla is an open-source FTP server for Windows. It supports FTP and FTP over TLS, the latter can provide encryption between the server and the client. FileZilla server has a simple and easy-to-use interface. It provides the basic functions expected in an FTP server, such as creating user accounts, speed limits, logging, IP filtering, groups, and fine-grained permissions. For basic FTP tasks , this is a good choice. It lacks corporate functions, so I will be cautious when providing it to the outside world. It uses FTP by default, so it is not secure and you will need to enable FTP over TLS to encrypt traffic. The setup is easy, just run the installer, select a management port and start the server interface. Then, you only need to create a user or group with permissions to the home directory to start using it. 2.SolarWinds SFTP/SCP Server SolarWinds SFTP/SCP server is designed for network and system administrators. It is an ideal FTP server for backing up configuration files, downloading images, and transferring large files. By default, it is secure and uses TCP port 22 to safely transmit data over an insecure connection. I use it to back up the configuration on Cisco routers and switches. Installation is very simple, with minimal configuration , and you are ready to go. It can be set to run as a service, so it is always available. 3.Serv-U Serv-U is designed for small businesses that need to transfer files quickly, easily, and securely. Serv-U supports FTP and FTPS for secure file transfer. You can use SSL or TLS to encrypt communications to protect data during transfer. One of my favorite features of this product is the ability to transfer files from a web browser or mobile device. This eliminates the need for users to set up an FTP client to download or upload files. The web and mobile interface makes it easy for you to view, upload and download files. Using interactive drag and drop options, your users can share files from anywhere. Other features include support for large file transfers, monitoring sessions, and fine-grained control of bandwidth, storage, permissions, and access. You can also view and monitor logs in real-time to help troubleshoot and audit access. Serv-U has excellent documentation and support. This is an enterprise-level product at a very affordable price. 4. Cerebus FTP Server Cerebus FTP server supports multiple file transfer protocols, such as FTP, SFTP, FTPS, HTTP/S, and SCP. Cerebus is a commercial product, divided into four versions: personal, standard, professional, and enterprise. Features include multiple protocol support, enhanced security features . Cerebus also includes great options for reporting and auditing data and user activity. It also includes robust file integrity checks using strong checksums. Cerebus provides four different versions, offering personal use options up to corporate business use. 5. Titan FTP Server Titan FTP is a commercial product for small businesses, and it also has different versions. Just like other FTP server programs, Titan supports multiple protocols for secure file transfer. Titan allows you to configure granular control to the user level and set permissions per server, group or user. Titan also includes the web interface in the Enterprise Edition and allows clients to access and upload files without the need for an FTP client. Titan has a built-in mechanism to prevent hackers from intruding into the product. If an unauthorized password guessing attempt is detected, the server can prohibit future access from the client IP.
