Network resource processing method and device, gateway, controller and storage medium

Abstract

The embodiment of the invention provides a network resource processing method and device, a gateway, a controller and a storage medium. Through the application network resources are stored locally. Only the currently occupied network resources need to be additionally stored in a preset resource list, and the corresponding relationship between the network resources and an occupation identifier forjudging whether the network resources are occupied by the network server or not does not need to be created for each network server which currently establishes the communication connection, so that the storage space of the gateway can be saved. The gateway selects a first network resource from the at least one network resource. Whether a first network resource is occupied currently needs to be judged. Whether the first network resource exists or not can be searched in the preset resource list, and only part of network resources in the first preset resource set are generally stored in the preset resource list. The network resources stored in the preset resource list are less, so that the determination efficiency of determining whether the first network resource is currently occupied or notcan be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a network resource processing method, device, gateway, controller and storage medium. Background technique [0002] Network Address Translation (NAT, Network Address Translation) technology is a conversion technology that converts a private IP (Internet Protocol, Internet Protocol) address into a public IP address, or converts a public IP address into a private IP address, and is widely used In the scenario where each LAN is connected to the Internet, it not only solves the problem of insufficient public IP addresses, but also enables the LAN to effectively avoid external attacks, hide and protect terminals located in the LAN. [0003] Wherein, the terminals located in the local area network can access the Internet through the gateway. The gateway has reserved IP and multiple ports, and the IP and each port can be combined into a group of network resources arbitraril...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that in related technologies, the number of corresponding relationships that the gateway needs to maintain is equal to the product of the total number of reserved network resources and the number of network servers that have established communication connections, resulting in a very large number of corresponding relationships that need to be maintained , will take up a lot of storage space on the gateway

[0007] Secondly, if another terminal located in the local area network also requests to establish a communication connection with another network server located in the Internet, after the gateway selects a group of network resources from multiple groups of network resources, it needs to judge the selected group of network resources. Whether it is currently occupied or not, it is necessary to search for the occupancy identifier corresponding to the group of network resources in the corresponding relationship created for each network server that has currently established a communication connection, and then determine whether the selected group of network resources is currently occupied, because the corresponding The number of relationships is very high, resulting in an inefficient determination of whether the selected set of network resources are currently occupied
