technical field

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

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 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 simultaneously and be connected to different networks, but this requirement cannot be met in the prior art, which will limit the development of the POS machine security field.
