In this embodiment, the above-mentioned electronic device can upgrade the original message forwarding application running in the second memory area to target message forwarding when the number of established connections in the second memory area is a preset value (for example, 0). application.

In practice, after the client (such as the terminal devices 101, 102, and 103 shown in FIG. 1 ) sends a message forwarding request to the above-mentioned electronic device, the above-mentioned electronic device will establish a connection between the client and the background server (such as the background server shown in FIG. 1 ). server 107, 108, 109), and generate connection information. Wherein, the above-mentioned connection information can include: the port number of the client, the IP address (Internet Protocol Address, Internet Protocol Address) of the client, the IP address of the background server, the port number of the background server, TCP (Transmission Control Protocol, transmission control protocol ) sequence number, ACK (Acknowledgment, confirmation character) number, statistical information (such as the number of packets), etc. After receiving the update request and passing the verification of the target message forwarding application information, each time the above electronics receives a message forwarding request sent by a client, it can determine whether the number of connections established in the second memory area is the above preset value , if it is not the above preset value, a connection can be established in the first memory area. When the number of connections in the second memory area drops to the preset value, the original message forwarding application running in the second memory area is upgraded to a target message forwarding application.

In this embodiment, the above-mentioned electronic device can upgrade the original message forwarding application running in the second memory area to the target message forwarding application through the following steps: first, the above-mentioned electronic device can load the above-mentioned target message forwarding application.

To verify the user information performing the upgrade operation, it can be determined whether the user indicated by the user information has the hot upgrade authority to determine whether the verification has passed. If yes, the user information has passed the verification; if not, the user information has passed the verification. User information failed verification. To verify the operation time of performing the upgrade operation, you can determine whether the operation time is greater than the operation time of the last upgrade operation to determine whether the verification is passed. If it is greater, the operation time passes the verification; if it is not greater, the Operation time failed validation. To verify the verification information of the above-mentioned target message forwarding application, it may be determined whether the above-mentioned verification information passes the verification by matching the above-mentioned MD5 value with a preset value.
