Problems solved by technology

Therefore, the number of TCP connections established by the front-end processor on the network side is relatively large, which greatly wastes network resources.
In addition, when multiple outlet terminals exchange outlet service packets with the front-end processor at the same time, since the front-end processor needs to establish different TCP connections for all outlet terminals, the service load of the front-end processor will be too large, and it is likely to cause Leading to the paralysis of the front-end processor, so that the transmission of network service packets cannot be realized

Embodiment 1

[0077] In this embodiment, the implementation process of the present invention is described by taking the above-mentioned outlet terminal as a POS machine and the above-mentioned outlet service message as a POS message as an example. In addition, in this embodiment, the number of TCP connections directly established between one network device and the front-end processor is taken as an example for description.

[0078] When the outlet terminal is a POS machine, and the outlet service message is a POS message, see image 3 , since the POS message carries a transmission protocol data unit (TPDU) for identifying various information of the POS message, therefore, preferably, when the present invention carries the identification of the terminal of the network point in the service message of the network point , the terminal identifier set for the terminal of the current network point may be carried in the TPDU in the service message of the network point, for example, carried in the s...

Embodiment 2

[0119] In this embodiment, the implementation process of the present invention is described by taking the described network point terminal as a TCP terminal, that is, the network point terminal connected to the network device through TCP, and the described network point service message as a TCP data message as an example. . In addition, in this embodiment, the number of TCP connections directly established between one network device and the front-end processor is taken as an example for description.

[0120] When the network point terminal is a TCP terminal, and the network point service message is a TCP data message, the TCP data message only carries TCP data, and there is no TPDL similar to the POS message that can be used for identification The field of various information of TCP data message, therefore, the present invention can increase identification domain in TCP data message, for example, in the head of TCP data message The identification field is added at the end, an...

Abstract

The method thereof comprises: setting different terminal IDs respectively corresponding to different network-point terminals; the network device establishes the TCP connection with the front-end processor; the amount of TCP connections are less than the amount of the network-point terminals; after the current network device directly connected to the network-point terminal receives the network-point service message, it adds the terminal ID corresponding to the current network-point terminal into the network-point service message, and then sends it to the front-end processor through the TCP connection; the front-end processor adds the service process result and the terminal ID corresponding to the current network-point terminal into the network-point service message constructed by itself, and sends it to the current network device; in term of the terminal ID carried by the network-point message the current network device sends the network-point service message from the front-end processor to the current network-point terminal.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and system for transmitting network point service messages. Background technique [0002] At present, with the continuous development of information technology and network economy, outlet business has been widely used by people. In outlet business, outlet terminals, such as POS machines and various TCP terminals, are installed at each outlet, and users log in to the front-end processor in the background through each outlet terminal to perform various transactions. For example, set up POS machines in major shopping malls, supermarkets and gas stations, and connect the POS machines to the front-end computers in the bank responsible for card account processing. After that, when users consume, they only need to swipe their cards on the POS machines You can pay the amount you spend. [0003] figure 1 It is a schematic structural diagram of a system for realizing network ...
