Review and List of the Top TFTP Servers with Features, Comparison, and Pricing. Select the Best TFTP Server From This List Based on Your Requirements:

In the Computer Networking Infrastructure or Client/Server Architecture, transferring files is the fundamental aspect to transfer data from one end to another. Now, when it comes to transferring files, the first thing which comes to our mind is – FTP (File Transfer Protocol).

Undoubtedly, FTP is the most reliable and secure means of exchanging data with a host computer. Besides, it is the most widely used client/server protocol with many advantages and applications, as well.

Yet, there are situations when organizations or users require a simple method to transfer data over a network. That’s the reason the TFTP protocol came into existence.

TFTP Server

What Is The TFTP Server?

TFTP stands for a Trivial File Transfer Protocol that is uniquely developed to simplify the sophisticated way of the file transfer. Or you can say that the TFTP server is a simply designed protocol that works on User Datagram Protocol. Unlike FTP, it does not use Transmission Control Protocol (TCP) to transfer the data.

Most importantly, the implementation of the TFTP server protocol is applied where there are no security and authentication mandatory. It is the reason why TFTP is rarely exercised in a computer network because the lack of security makes it vulnerable over the internet.

As a result, the application of the TFTP server protocol is usually helpful in transferring boot as well as configuration files among linking computers in a confined network setup.

Generally, the data transfer in the TFTP server initially starts with port 69. Additionally, the sender and receiver can select the data transfer ports after the connection starts.

A TFTP server requires a minimal amount of storage for its implementation. With this feature, it becomes a precise, organized way to boot computers that do not possess any storage drives. Also, making itself a core element of PXE (Preboot Execution Environment) and network boot protocol.

How Does TFTP Work?

TFTP is the lightweight and more straightforward file transfer protocol, it is somewhat similar to FTP. But offers fewer features than FTP and hence comes with a smaller footprint. Let’s see the basic theory of operation and how does the TFTP server work.

  • Like FTP, TFTP also uses the same client/server software to establish a connection between two computers. It is an application layer protocol (client-server) that has TFTP client software for TFTP clients; and TFTP server software for TFTP servers.
  • Note, TFTP uses the User Data Protocol (UDP) layer to transport data over the network. As UDP is much more straightforward than the complicated TCP layer, it requires less code space. Hence, it makes TFTP fit inside tiny storage.
  • Now, a TFTP client has to open the server socket on the server’s IP address on UDP port 69. It is because of the server relies on port 69 for connection with the client. The client has to establish a UDP connection to the server.
  • After the connection gets established, the client can send the message request to the server. There are different types of message requests to the server.
  • For Example, the client can send a Read Request (RRQ) if it wants to fetch any file from the server. Or Write Request (WRQ) to transfer any file over the network.
  • The TFTP divides the message to be sent in the blocks of 512 bytes. The noticeable part – the last block of every file is always lesser than 512 bytes. So, the receiver could interpret that it’s the last block from the sender.
  • Each block is then transferred as a TFTP data message, and every block is assigned with a TFTP number. Now, each block is carried separately inside a UDP message.
  • Since not every time the size of the last block would be less (in case if its exact multiple of 512), then the sender sends another block of zero bytes to convey that the transfer part is over.

Since the TFTP follows check and pause protocol, it sends each block one by one in succession. At first, when the sender sends the first block, it starts a preset block timer. If for the sent block, an acknowledgment is received within the block timer, then the second block of the file is sent. And if not, again, the first block of the file is sent. Hence, this is the way TFTP achieves flow control.

TFTP Message Requests

The TFTP usually has five different types of messages, as given below.

  • RRQ: It is the request made by the TFTP client to read or fetch a file from the server.
  • WRQ: It is the request made by the TFTP client to transfer or send a file over the server.
  • DATA: These are the TFTP DATA messages that contain blocks of a file to be sent over the server.
  • ACK: It is the response from the receiving side against acquiring a block of the file to the sender.
  • ERROR: It is a message sent to the peer concerning any invalid operation performed.

TFTP Server Configuration Uses

Majority of IT professionals and Networking System Admins use TFTP server for:

  • Transferring files between devices in a local setup.
  • For upgrading codes of files.
  • Backing up network configurations as well as router configurations files.
  • Booting of devices remotely without any storage drives.
  • Booting of computer in a restrained setup without any hard disk
Fact Check: According to the International Data Corporation Research, in the first quarter of 2019, revenue from the worldwide server market increased by 4.4% compared to the previous year.

Check the statistics graph below:

TFTP-server-market-share

The current scenario of the overall server market depicts that robust growth may remain. Although, there may be some declining points such as a reduction in market share by the second quarter of 2019, further Average Selling Prices (ASP) could support revenue growth for many vendors.
