Problems solved by technology

[0003] At present, NAT IP is usually issued synchronously when user services activate broadband services. When a large number of user services need to be activated in batches, this method requires the orchestration controller to issue NAT IP resources to each user at the same time. The problem of high concurrency of servers can also easily cause waste of NAT IP resources

Abstract

The invention relates to the technical field of network virtualization, and discloses a method and device for allocating an NAT IP and a storage medium, and the method comprises the steps: analyzing message feature information based on a first user message which is sent by any client and aims at a target service, and if the NAT IP corresponding to the message feature information does not exist, sending the first user message to the client; if not, generating an address request event based on the message feature information, sending the address request event to the arrangement controller, after receiving an NAT IP returned by the arrangement controller, establishing a corresponding relation between the client and the NAT IP based on the message feature information and the NAT IP, analyzing target message feature information based on a target user message sent by the client, and sending the target message feature information to the arrangement controller; and searching the NAT IP corresponding to the target message feature information in the corresponding relationship, and allocating the NAT IP to the target user message, so that the mode of allocating the NAT IP to the client according to the demand avoids high concurrency of an orchestration controller and waste of NAT IP resources.

Description

technical field [0001] The present disclosure relates to the technical field of network virtualization, and provides a method, device and storage medium for allocating NAT IP. Background technique [0002] Currently, Network Address Translation (NAT) technology is widely used in gateway devices for communication between private networks such as corporate LANs, institutional LANs, and personal LANs and public networks. NAT is a technology that maps the Internet Protocol (IP) address of the internal private network into a legal public network IP address, but shields the real address of the private network user, making each private network IP address invisible to each other. And perform many-to-one conversion between the private network IP address of each LAN and the public network IPv4, which solves the problem of insufficient public network IPv4 addresses to a certain extent, and at the same time improves the security of private network users. [0003] At present, NAT IP is ...
