System and method for trivial file transfer protocol including broadcasting function

Abstract

A system and method for a Trivial File Transfer Protocol (TFTP) includes a broadcasting function in which a new option is added to the TFTP to allow several clients to connect with one server to simultaneously download files. The method includes a first step of transmitting, by a first client, an extended read request message to request broadcasting file transmission to a server; a second step of transmitting, by the server, an option acknowledgement message notifying that the first client is a master client to the first client; a third step of transmitting, by a second client, the extended read request message to request broadcasting file transmission to the server; a fourth step of transmitting, by the server, the option acknowledgement message notifying that the second client is not a master client to the second client; a fifth step of broadcasting, by the server, data and then waiting to receive an acknowledgement message from the first client; and a sixth step of effecting, by the server, repetition from the fifth step until the server transmits all remaining data when the server receives the acknowledgement message from the first client.

Description

technical field [0001] The present invention relates to a system and method for simplifying a file transfer protocol (hereinafter referred to as "TFTP"), and more particularly, to a system and method for TFTP including broadcast functionality, wherein new options are added to TFTP, To allow multiple clients to connect to a server to download files at the same time. Background technique [0002] In most systems, data is represented as units called files. Files and parts of files need to be transferred in order to transfer data between systems. [0003] In systems interconnected by a network, where a user of one system wishes to receive data from other systems to his or her system, or transfer data from his or her system to other systems, i.e. when the systems wish to communicate with each other In the case of communication, rules and regulations are required to allow these systems to communicate with each other. The rules and regulations are referred to as protocols. [0...

Problems solved by technology

[0027] Also, although RFC2090 is adopted to support multicast for TFTP, there is a high possibility that multicast will not be necessary depending on the situation

In the case of file transfer for normal operation in an environment where an internal network is established in one device, where one main part acts as a TFTP server and the rest acts as a TFTP client, there is a one-to-one transfer that takes too much time and causes a transfer error high probability of
