A multi-routing method for the coexistence of POS machine wifi and Ethernet

Abstract

The invention relates to a multi-routing mechanism for the coexistence of WIFI and Ethernet in a POS machine. Firstly, the priority level of the network connection management module in the POS terminal based on the android system is canceled, and the ports of the WIFI module and the Ethernet module are independently controlled; when the network is connected , respectively add the DNS server IP address, analyze the requested link URL at the same time, determine the service requirement type of the currently requested link URL, and configure the route of the link URL; the link URL request command that requires Internet service is sent to the connection port of the WIFI module, The request command of the link website that requires financial transaction services is sent to the connection port of the Ethernet module; using the above mechanism, the two network connections of the POS terminal can exist at the same time, and the DNS can be added or deleted in time according to the status of network connection or disconnection Address information; at the same time, according to the current link request and application requirements, different service requests are used to send different network connections, which ensures the security of the POS terminal when conducting transactions.

Description

technical field [0001] The invention relates to the technical field of communication, and specifically refers to a multi-routing method for the coexistence of WIFI and Ethernet in a POS machine. Background technique [0002] To access the network, the existing POS terminal equipment must connect to the AP (Access Point, access point) through WIFI, or connect to the Ethernet through a wired network port, or dial up to the Internet through a 3G module. On the multimedia POS machine running the Android system, at the same time, since only one network connection can be opened in the network connection management module, according to the set priority, if the priority of the opened network connection is lower than the priority of the current connection, then Close the open connection and keep the current connection; if the priority is higher than the current connection, when the current network connection is closed, the open connection will take effect. At this time, the applicati...

On the multimedia POS machine running the Android system, at the same time, since only one network connection can be opened in the network connection management module, according to the set priority, if the priority of the opened network connection is lower than the priority of the current connection, then Close the open connection and keep the current connection; if the priority is higher than the current connection, when the current network connection is closed, the open connection will take effect. At this time, the application requirements that two network connections exist at the same time cannot be met. However, in Multimedia POS machines provide Internet services and financial transaction services. When different services have different requirements for security, financial transaction services have much higher requirements for network security than Internet services, so the financial transaction service network and Internet services Network isolation requires two network connections to exist at the same time and be connected to different networks, but this requirement cannot be met in the existing technology, so it will limit the development of POS machine security field
