Embodiment 1
[0043] A method for automatically batch upgrading data communication terminals based on a multicast protocol, comprising:
[0044] Step S100: The upgrade server invokes the upgrade file and encapsulates the upgrade file into a data network packet according to the set multicast sending address, receiving address, source port number, and destination port number, and pushes it to the networking device in a multicast manner;
[0045] Step S200: After receiving the multicast data, the networking device forwards the data to each data communication terminal joining the multicast group;
[0046] Step S300: The data communication terminal triggers the upgrade when it detects that there is a matching upgrade file in the multicast group, such as figure 2 Shown:
[0047] After the data communication terminal is powered on, it detects the multicast group and requests to join. After joining, it detects whether there is an upgrade file in the multicast group. If it exists, it enters the st...
Embodiment 2
[0054] combine figure 1 As shown, an automatic batch upgrade system for data communication terminals based on a multicast protocol includes a communication-connected upgrade server, a networking device, and a data communication terminal. The upgrade server includes a data stream encapsulation module, a port setting module, a storage module and The control module consists of:
[0055] The storage module is used for importing and storing upgrade files, so as to realize the storage of different types of upgrade files. ;
[0056] The port setting module is used to specify the corresponding multicast sending address, receiving address, source port number and destination port number, and pass it to the data stream encapsulation module;
[0057] The port setting module integrates the following functional interfaces: the configuration interface of the local server IP address (i.e. the multicast source address), the multicast destination IP address interface, the port number interfac...

Abstract
The invention discloses an automatic batch upgrade method for data communication terminals based on a multicast protocol. The upgrade server calls the upgrade file and encapsulates the upgrade file into a data network packet according to the set multicast sending address, receiving address, source port number, and destination port number. , and push it to the networking device in the form of multicast; after receiving the multicast data, the networking device forwards the data to each data communication terminal that joins the multicast group; the data communication terminal detects that there is a match in the multicast group The upgrade is triggered when the file is upgraded. Also disclosed is an upgrade system, which includes an upgrade server connected by communication, a networking device and a data communication terminal. The upgrade server is composed of a data flow encapsulation module, a port setting module, a storage module and a control module. By building a multicast upgrade environment, the data communication terminal automatically detects the upgrade data and triggers the upgrade after it is powered on, so that the batch upgrade of the data communication terminal is realized and the efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of data communication terminal equipment, in particular to an automatic batch upgrade method for data communication terminals based on a multicast protocol. Background technique [0002] The multicast protocol (multicast protocol) can copy the data sent by a host to multiple hosts joining the multicast through a network switch or routing device. It is a one-to-many communication method. The advantages include: 1) It can save The system resources and bandwidth of the host that sends the data; 2) Multicast is selectively copied to the host that requires it; 3) Multicast can be widely spread across the public network, while broadcast can only be spread within the LAN or a dedicated broadcast network ; 4) The multicast can save the bandwidth of the network backbone. [0003] Data communication is widely used in all aspects of people's life in the digital information age. As a data communication terminal carryi...
