Other than the above, there's perhaps the option of using some other protocol which is TCP based e.g., FTP, SCP etc., as this might give better performance than TFTP. The remote host may be specified on the command line, in which case tftp uses host as the default host for future transfers (see the connect command below.) Options-4.
If you have a number of routers/sites that have direct connectivity between themselves and they are geographically closer to each other than back to your hub, one option you have is to set up a router as the TFTP server. tftp is a client for the Trivial file Transfer Protocol, which can be used to transfer files to and from remote machines, including some very minimalistic, usually embedded, systems. If you can reduce the latency, then you can transfer more blocks in any given period of time. If you have a round-trip latency of 100ms between your client and server then you can at most transfer 10-blocks of data per second. Slow tranfer over the WAN is sometimes caused by low bandwidth, but more usually it's due to high latency. Servers listen on port 69 for the initial client-to-server packet to establish the TFTP session, then use a port above 1023 for all further packets during that. There are measurements in the aforementioned RFC that show a 2.8x performance improvement when using 1428-byte blocks compared to 512-byte blocks. The default TFTP blocksize is 512-bytes, but if your client and server both support RFC 2348 TFTP Blocksize Option then the blocksize can be increased to approximately 1450-bytes.
Now, run the following command on your TFTP server to find the IP address of the TFTP server. The tftp-hpa client program should be installed.
#Tftp client install#
With this in mind there are really only two ways to increase TFTP performance. To install the tftp-hpa TFTP client on Ubuntu, run the following commands: sudo apt update. As you may be aware, the way TFTP works is that it transfers a single data packet containing one block of data, and that packet must be acknowledged before the next packet can be sent.
