It should be noted that, in the above process, the management server stores the local area network IPv4 addresses and the port numbers of the local area network ports of the two electronic devices in correspondence with the corresponding device information.

And 2, establishing connection. The first electronic device and the second electronic device can establish a connection based on the local area network IPv4 address, or establish a connection based on the wide area network IPv4 address, which will be described below.

In an implementation manner, if it is determined that the first electronic device and the second electronic device are located in the same local area network based on the third IPv4 address and the fourth IPv4 address, the first electronic device and the second electronic device establish connection based on the local area network IPv4 address, that is, the first electronic device establishes connection with the second electronic device based on the third IPv4 address, the third port, the fourth IPv4 address, and the fourth port, and stores a corresponding relationship between the third IPv4 address, the port number of the third port, the fourth IPv4 address, and the port number of the fourth port, so as to obtain target connection information. The process of establishing the connection is the same as the process of establishing the connection based on the IPv6 address, and is not described herein again.

In another implementation manner, if the first electronic device determines that the first electronic device and the second electronic device are located in different local area networks based on the third IPv4 address and the fourth IPv4 address, the first electronic device and the second electronic device perform NAT traversal respectively, and then establish connection based on the wide area network IPv4 address. The process includes that a first electronic device performs NAT traversal based on a first NAT device, a second IPv4 address and a second port, sends a traversal message to a management server, the traversal message is used for indicating the second electronic device to perform NAT traversal based on first device information, the management server forwards the traversal message to the second electronic device, the second electronic device receives the traversal message, performs NAT traversal based on the NAT device of the second electronic device and the IPv4 address of the first electronic device, sends a traversal response to the first electronic device, the traversal response is used for indicating that NAT traversal is completed, the first electronic device receives the traversal response, establishes a connection with the second electronic device based on the first IPv4 address, the first port, the second IPv4 address and the second port, and stores a correspondence between the first IPv4 address, the IPv4 address of the first port, the second IPv4 address and the port number of the second port, thereby obtaining target connection information. The process of establishing the connection is the same as the process of establishing the connection based on the IPv6 address, and is not described herein again.

The above NAT traversal process is exemplarily described. The first electronic device sends a first message to a wide area network address of the second electronic device through the first NAT device based on the local area network address of the first electronic device, that is, the first electronic device sends the first message to the second IPv4 address and the second port through the first NAT device based on the third IPv4 address and the third port, where the first message carries the third IPv4 address, the third port, the second IPv4 address and the second port, and the first NAT device receives the first message and records a first entry to complete NAT traversal, where the first entry includes a correspondence between the third IPv4 address and the third port, and between the second IPv4 address and the second port, and through the first entry, the first NAT device can forward data from the wide area network address of the second electronic device to the first electronic device. The second electronic device can complete NAT traversal by using a method similar to that of the first electronic device, so that the second NAT device records a second entry, where the second entry includes a fourth IPv4 address and a fourth port, and a correspondence between the first IPv4 address and the first port, and the second NAT device can forward data from the wide area network address of the first electronic device to the second electronic device through the second entry.
