Show  Posted at 09:35h in BlueFinch, Managed File Transfer Transferring files over the internet is a common task in today’s digital world and it’s important to find and use protocol that fits your organisation’s needs. by: Ekron Dries A protocol is a set of rules and messages between a sender and a receiver. It functions much like a language that both ends of the network understand so the data arrives uncorrupted and with a proper file name. When it comes time to choose a protocol, there are many options that are still commonly used: FTP, FTPS, SFTP, HTTP, TFTP, among others. Out of all these file transfer protocols, we’ll be concentrating on three in this blog: FTP, TFTP and FileCatalyst, which uses a proprietary UDP (User Datagram Protocol) based protocol. All three protocols are used for file transfer, but there are some significant differences between them. What is FTP?FTP stands for File Transfer Protocol and it is used to send and receive files from a remote computer. FTP establishes two connections between the client system and the server system, one for control information and the other for data to be transferred. One secure version of this protocol is called FTPS, which uses SSL to encrypt data in transit. Control information carries commands and response. Authentication must be done initially by way of validating username and password and, once complete, files can be transferred between two systems. FTP handles both binary and text format files. When an FTP client requests to connect to an FTP server, a TCP (Transmission Control Protocol) connection is established to the FTP server’s port 21, which is reserved for FTP. After authentication is done, another TCP connection is established for the actual data transfer on another ephemeral port, usually above 1024. What is TFTP?TFTP stands for Trivial File Transfer Protocol. TFTP is much simpler than FTP and executes file transfer between client and server processes. However, it does not provide user authentication and other useful features supported by FTP. While FTP uses TCP, TFTP uses UDP, which both makes it an unreliable protocol and causes it to use UDP-supported application layer recovery. How TFTP Works:
What Makes FileCatalyst Different?FileCatalyst uses a proprietary UDP based protocol for file transfer, and also borrows concepts from FTP and TFTP protocols. FileCatalyst vs. FTP FileCatalyst uses a TCP Control connection just like FTP, but the data is sent via UDP to provide acceleration and immunity to latency and packet loss on a network. FileCatalyst uses SSL for control connection and AES for UDP data transfers. FileCatalyst vs. TFTP Unlike TFTP, FileCatalyst sends many blocks of data at once to maximize bandwidth. It also incorporates many custom commands for dynamic bandwidth control, checkpoint restarting, MD5 checksum verification, compression, file attributes transmission and sending many small files over a single data channel by auto archiving small files into a single archive. FileCatalyst was designed for bulk data transfer and bandwidth optimization over long distance networks. Which Protocol Will Make the Most Difference?Ultimately, TFTP is best when transferring data locally within a data center where security and network stability is not an issue. FTP and its secure version FTPS are best for transferring files over wide area network where files are smaller or the volume of files is not a concern. FileCatalyst is the best option for sending large files (>2GB) over wide area network using public internet connections and where the transfer time is critical due to business needs. FileCatalyst is also more secure due to AES encryption of files in flight. Discover the power of FileCatalystIf you’re looking for an advanced method of transferring large files quickly and securely, FileCatalyst is a great option.

FTP stands for File Transfer Protocol. It is used to send/receive file from the remote computer. It is defined in RFC959. FTP establishes two connections between client system and server system, one for control information and the other for data to be transferred. Control information carries commands/response. Authentication need to be done initially by way of validating username and password. Once it is done files can be transferred between two systems. FTP handles both binary and text format files. When a FTP client requests to connect to the FTP server, a TCP connection is being established to the FTP server’s port 21 reserved for FTP. After authentication is done, another TCP connection is being established for the actual data transfer on port number 20. TFTP stands for Trivial File Transfer Protocol. It is defined in RFC783. It is simpler than FTP, does file transfer between client and server process but does not provide user authentication and other useful features supported by FTP. TFTP uses UDP while FTP uses TCP. As TFTP is unreliable protocol due to UDP, it uses application layer recovery supported by UDP. This is done by embedding a small header between the UDP header and the data. This header incorporates codes for example read, write and acknowledgement along with numbering scheme which numbers 512 bytes of data. These block numbers provided are used to acknowledge the receipt and re-send the data in case of checksum failures. TFTP sends one block and waits on acknowledgement before sending another block. Main differences between FTP and TFTP are
In today’s digital world, it is common to transfer files over the internet and it is crucial to choose a protocol that defines your organization’s needs. So, there are different protocols available that can do this job and two of the most important ones are the File Transfer Protocol (FTP) and Trivial File Transfer Protocol (TFTP). In this article, we will focus on these two protocols and their significance along with some drawbacks so that you can choose accordingly as per your requirement. What is File Transfer Protocol (FTP)The main function of FTP is to send and receive files over the Internet. Its full form is file transfer protocol which is used to establish two different connections with a client and server; one for control information and the other for data transfer; after establishing connection, you can transfer files to any system. FTP can handle files in both binary and text formats. The initial FTP client software relied on the DOS command prompt, which had standardized commands and syntax. The availability of graphical user interface (GUI) to the users has eased the process of uploading and downloading documents since then, it is based on RFC 959 standards, with additional RFCs providing safety precautions. How FTP worksA TCP connection to the FTP (reserved port 21) is created when an FTP client wishes to connect to the FTP server. After authentication, a new TCP connection is created on port number 20 for the actual data transmission. So, FTP establishes two connections when copying a file from one host to another: one for data transmission and one for control. FTP is an application layer protocol. When transferring files over FTP, it can solve difficulties like different file conventions, ways of representing text and data, and a different directory layout. The communication in the control connection (port 21) is based on basic rules. The data connection, on the other hand, is more complicated since it employs several instructions to transfer the various types of data. Even though the user is authenticated at the time of connection formation, FTP is not secure since the user’s password is in plain text, and the data is also sent in plain text, which may be intercepted by the attacker using SSL (Secure Socket Layer). What is Trivial File Transfer Protocol (TFTP) protocolTFTP is an acronym for Trivial File Transfer Protocol which is also used for sending files from a client to a host. TFTP uses port number 69 for its service and the data is delivered via UDP. It is less complicated than FTP because it transfers files between client and server without using authentication and other valuable features that FTP offers. The communication is accomplished by inserting a short header between the data and the UDP header. This header contains read, write, and acknowledgment codes, as well as a 512-byte data numbering scheme. Sending or receiving files over TFTP requires no security or encryption. TFTP can easily be implemented using a small amount of memory and that makes it a valuable tool for booting computers and devices without hard disk drives. Comparison between FTP vs TFTPIn this section we will compare the features of FTP and TFTP and what are the similarities and differences between them.
ConclusionProtocols are necessary for communication and tell you about the standards that need to be followed between multiple network devices. Two of the most commonly used protocols are file transfer protocol (FTP) and trivial file transfer protocol (TFTP). This post compared these two network protocols; discussed their significance and their drawbacks. As their name suggests, both of these are used to transfer files but there are also some differences between them which have also been discussed at the end. |
