Data transmission method, server conversion device, client conversion device and system

Abstract

The invention discloses a data transmission method, a server conversion device, a client conversion device and a system, and relates to the field of computer technology, the main purpose of which is to simulate the use of multicast communication in the entire network environment under the limited conditions of the current network environment Function. The technical solution of the present invention includes: the server conversion program obtains the data message, and judges whether the data message is a multicast data message; if it is determined that the data message is a multicast data message, then the data message is The text is converted into a unicast data message; the converted unicast data message is sent to the client conversion program on the network side, so that the unicast data message is converted into a multicast data message by the client conversion program file and send it to the client. The invention is mainly applied in the process of sending data from the server to the client in the network environment.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method, a server conversion device, a client conversion device and a system. Background technique [0002] With the rapid development of computer technology and network technology, any computer can exchange information conveniently. In computer networks, there are two traditional data transmission methods: unicast and broadcast. Among them, unicast is a point-to-point connection between the client and the server, that is, a separate data transmission is established between the client and the server. Channel, the server sends data packets to the specified client; broadcast is a one-to-many connection between the server and the client, that is, the server sends data packets to all clients in a network segment, regardless of whether the client needs it, a network All clients in the segment will receive the broadcast packet. [0003] With the increasing popula...

Problems solved by technology

In practical applications, in order to prevent network traffic attacks generated during multicast communication and ensure the security and reliability of the entire network, the entire network may disable or turn off the multicast communication function; however, in this network environment, it may be necessary to Use multicast communication for data transmission to improve the efficiency of data transmission. Therefore, under the constraints of the current network environment, allowing the use of multicast communication functions in the entire network environment has become an urgent problem to be solved.
