Service calling method, device and equipment and computer readable storage medium

Abstract

The embodiment of the invention provides a service calling method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining a protocol address and a port of a first application when a second application calls the service of the first application to achieve the service calling; searching a floating address having a mapping relationship with the protocol address and a floating port having a mapping relationship with the port from a preset mapping relationship list; and establishing network connection between a first application and a second application by adopting the searched floating address and floating port, thereby realizing service calling between the second application and the first application.

Description

technical field [0001] The present application relates to the technical field of communication, and relates to but not limited to a service calling method, device, equipment and computer-readable storage medium. Background technique [0002] Currently, due to the rapid development of Internet technology, Internet Protocol (Internet Protocol, IP) address resources are in sharp shortage. Therefore, many applications work with intranet addresses behind a firewall. When the application needs to provide services externally, the gateway will assign a floating IP (Floating IP) and floating port (Floating port) to the application for access by external devices; and the gateway will assign the application's internal IP, internal port, floating IP and The floating port is used for Network Address Translation (NAT). However, some applications will carry their internal IP and internal port in the payload of the message. When this kind of message passes through the NAT conversion of the...

Problems solved by technology

However, this solution needs to set up different application-layer address gateways in advance for different application protocols. Every time a new protocol appears, it is necessary to develop its corresponding packet parsing rules; The text needs to be analyzed in depth, which increases the response time of the service

More importantly, the above application gateway cannot work for applications whose message payload format is not fixed or whose message payload is encoded or encrypted (such as blockchain, peer-to-peer P2P).
