Server message processing method, system, electronic equipment and readable storage medium

Abstract

The invention discloses a server message processing method, a system, electronic equipment and a readable storage medium. The method comprises the following steps: the NAT equipment receives an original message issued by a server deployed in an extranet to an intranet host; converting a message header target address of the original message into an intranet address of forwarding equipment to obtain a message after address conversion; based on the intranet address and the port of the forwarding equipment, sending the message subjected to address conversion to the forwarding equipment; the forwarding device receives the message sent by the NAT device; analyzing the message content of the message, and obtaining an intranet host address and an interception port carried by the message; and sending the message to a corresponding intranet host based on the intranet host address and the interception port. According to the invention, only one public network address needs to be occupied by the forwarding equipment, the public network address resource is prevented from being influenced, the message sending error caused by the aging of the mapping address of the NAT equipment is avoided, and the real-time performance of sending the message to the intranet host by the extranet server is ensured.

Description

technical field [0001] The invention relates to the technical field of communication between an external network and an internal network, in particular to a server message processing method, system, electronic equipment and a readable storage medium. Background technique [0002] Network Address Translation (NAT) is a protocol for converting an IP address in an IP datagram header into another IP address. In practical applications, NAT is mainly used to realize the function of private network accessing public network, so as to represent more private IP addresses through a small number of public IP addresses, and slow down the exhaustion of available IP address space. [0003] At present, most of the communication scenarios between the external network and the internal network are: the internal network initiates a message data request, waits for the response from the external network, and completes a request when receiving the response information sent by the external network....

AI Technical Summary

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a server message processing method, system, electronic device and readable storage medium to solve the problem of public network address resources that exist when a server on an external network actively sends a message to a host on an internal network. Problems such as limit, message data sending error, etc.
