<p>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. <IMAGE></p> |
