In previous part of the topic we have learned about TFTP - Trivial File Transfer Protocol in quite general way. However, with the consultations of Computer Network Support technicians, there is following lines has been mentioned in respect to the TFTP.
Now lets just jump in into field where we will get to know how really TFTP works. Well, the scenario is quite easy to understand as TFTP sends a read and write command towards the server side in order to initiate communication, usually it sends a command specifically to Port-69 which comprises of a transmission mode and name of the file. In response of the request, by accepting the request the server answering the host using a particular data packet initiated from a newly port that will be kept engaged until the session remains alive. As the host gets the response back, it starts sending the bulk of data packets towards the server. All the data packets are of equal sized, for instance, 512 bytes. Against each of the data packets the server will respond back either it has been received successfully or not.
When the transmission comes to end the host will initiate to transfer a file consisting of less than the fixed size of 512 bytes which will point the server that communication is going to end by this. If somehow the very last packets comprises of 512 bytes as well, then it will merely sends an empty packets signaling server for the termination. However, the stuff may be a little bit confusing, but not to worry at all as you can better approach to Computer Remote Support expertise in order to guide yourself in forming up your own network setup.
