Problems solved by technology

[0007] At this stage, some methods for judging the local network and the remote network have a certain locality. When judging the network status, certain prerequisites are required. Once the prerequisites do not meet the requirements, the network status between networked devices cannot be accurately judged.

Embodiment Construction

[0025] Such as figure 1 As shown, a method for automatically identifying local and remote networks includes the following steps:

[0026] Assume that both device A and device B are networked devices, and the specific connection network status is unknown;

[0027] Step 1: Determine whether the SSID and MAC address of the router connected to device A and device B can be obtained. For example, some devices (such as mobile phones, tablets, laptops, etc.) can directly obtain the SSID and MAC address of the connected router through the information displayed inside the device. Basic information such as SSID and MAC address, some devices (WIFI modules, smart home appliances, etc.) cannot intuitively display the SSID and MAC address of the connected router.

[0028] Step 2: According to step 1, execute the judgment of step 2, if the SSID and MAC address of the router connected to device A and device B can be obtained, then execute step 3, otherwise, then execute step 4.

[0029] Step...

Abstract

The invention relates to a method for automatically identifying local and remote networks. The method disclosed by the invention comprises the following steps of judging whether an SSID and a MAC address of a router connected to equipment A and equipment B can be obtained or not at first; defining a communication protocol of a local area network if the SSID and the MAC address of the router cannot be obtained, and enabling the equipment A and the equipment B to perform information interaction by utilizing the communication protocol; and finally, judging according to an information interaction content. By means of the method disclosed by the invention, network environments, where equipment is, can be distinguished rapidly; and whether the equipment is in the same local area network can be judged.

Description

technical field [0001] The invention belongs to the technical field of network communication and relates to a method for automatically identifying local and remote networks. Background technique [0002] There are many types of network classification standards, and everyone generally agrees on a general network classification standard based on geographical scope. According to this standard, various network types can be divided into four types: local area network, metropolitan area network, wide area network and Internet. [0003] Local area network (LocalAreaNetwork) is within a local geographical range (such as a school, factory and institution), connecting various computers. A computer communication network composed of external devices and databases connected to each other, referred to as LAN. It can be connected with a remote local area network, database or processing center through a data communication network or a dedicated data circuit to form a large-scale informati...
