Target port determination method, apparatus and device, and readable storage medium

Abstract

The invention discloses a target port determination method, which comprises the following steps of: when a target request is obtained, determining target state data from state data respectively corresponding to a plurality of port sections; determining a target port section corresponding to the target state data by utilizing a preset corresponding relationship; traversing the target state data, and when idle information is detected, determining a port corresponding to the idle information in the target port segment as a target port; according to the method, traversal detection does not need tobe carried out on all ports; whether the idle port exists in the corresponding port segment or not is judged by utilizing the state data, and the target port is determined when the idle port exists in the port segment, so that the time required for determining the target port is reduced, the time required for the whole NAPT conversion is further reduced, and the information sending time delay isreduced; in addition, the invention also provides a target port determination device, target port determination equipment and a computer readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a method for determining a target port, a device for determining a target port, equipment for determining a target port, and a computer-readable storage medium. Background technique [0002] NAPT (Network Address Port Translation), that is, network address port translation, uses a legal public network address to correspond to different internal addresses with different protocol port numbers, and converts internal network addresses and ports into external network addresses and ports. That is, the conversion between <internal address + internal port> and <external address + external port>. NAPT is commonly used in access devices, and it can hide small and medium-sized networks behind a legal IP address. NAPT is also called "one-to-many" NAT, or PAT (Port Address Translations, port address translation), address overloading (address overloading). [00...
