Problems solved by technology

In a dual-active network, different port usage ranges are assigned to each network device. However, link failures and device failures will inevitably occur in the network. unbalanced
However, due to the fixed port resources allocated, after the port resources of the non-faulty network device are used up, the new packets cannot be NAT-transformed, resulting in service interruption of some private network terminals, so that the dual-active network continues to provide network The stability of the service is poor

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] First, a brief description will be given of related concepts involved in the method provided by the embodiment of the present invention.

[0025] NAT dynamic address translation is used to establish the address mapping relationship between the internal network and the external network. This method is generally applicable to the networking environment where a large number of terminals on the internal network need to access the external network.

Abstract

The embodiment of the invention provides a port resource allocation method and device. The port resource allocation method comprises the following steps: detecting the port resource use condition of each network equipment in a dual-master network; determining first network equipment with the minimum use of port resources in the dual-master network according to the port resource use condition of each network equipment; and distributing port resources which are not used on the first network equipment to each network equipment in the dual-master network. According to the scheme of the invention,the stability of continuously providing network services by the dual-master network can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a port resource allocation method and device. Background technique [0002] In the Internet, a network device equipped with NAT (Network Address Translation, Network Address Translation) technology can convert the IP address in the IP (Internet Protocol, Internet Protocol) data packet header into another IP address. The address is converted to a public network IP address, effectively alleviating the problem of insufficient IP addresses in the Internet. In the PAT (Port Address Translation) mode, the network device allows multiple private network IP addresses to be mapped to different ports of the same public network IP address, so that multiple private network terminals can share the same public network IP address. [0003] In a dual-active network, each network device is in a hot backup relationship. Each network device uses the same IP address for NAT conversion....
