Port configuration processing method, port configuration processing device and port configuration processing system on basis of network access

Abstract

The invention provides a port configuration processing method, a port configuration processing device and a port configuration processing system on the basis of network access. The port configuration processing method includes that CGN (carrier-grade NAT) equipment receives user identification, private network IP (internet protocol) addresses and application port network access information transmitted by terminals and acquires corresponding public network IP addresses according to the private network IP addresses, a first group of access ports used for accessing an application port of the first priority level and a second group of access ports used for accessing an application port of the second priority level. If an application port on an application server is determined to belong to the application port of the first priority level corresponding to the user identification according to pre-stored user identification and corresponding information of the application port and the first group of access ports and the second group of access ports are all occupied, then access ports in the second group are released and access can continue. By the port configuration processing method, the port configuration processing device and the port configuration processing system on the basis of network access, log server resources are saved while users can be guaranteed to access network application of high priority level continuously, and access viscosity of the users can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a method, device and system for processing port configuration based on network access. Background technique [0002] With the development of the Internet, the number of broadband users has increased sharply, and IP public addresses have been exhausted. In order to solve the problem of insufficient IP addresses, Network Address Translation (NAT) technology was proposed and Carrier-Grade Network Address Translation (Carrier-Grade NAT, CGN) devices support network access by multiple terminal devices. There are three types of NAT technologies: static address translation (Static NAT), dynamic address translation (Pooled NAT), and network address port translation (Port-Level NAT, NAPT). [0003] At present, NAPT is the most commonly used conversion method, that is, the CGN device converts the private IP address of the terminal device for network ac...

Problems solved by technology

[0004] However, if the fixed number of access ports allocated by the CGN device is used up during the process of users accessing various network applications, they cannot continue to access the remaining important application ports on the application server, which has certain limitations.
