Problems solved by technology

[0004] For example, both A and B have N IP addresses. Due to the large-scale activities held in A, the IP addresses in A are exhausted, and because the population of B moves to A, the address utilization rate of B drops to 50%.

Embodiment Construction

[0090] In practical applications, one or more IP address resources need to be shared between multiple CGN devices (including but not limited to routers / firewalls with NAT or Network Port Address Translation (NAPT) functions) to optimize address resources the goal of. The NAPT may also be referred to as network port address translation (PAT).

[0091] In order to realize the sharing of IP address resources, the following modules can be applied:

[0092] A. User configuration module;

[0093] The user configuration module is used to perform configuration involving IP addresses, and may perform at least one of the following operations:

[0094] 1) Device sharing priority configuration;

[0095] 2) Apply for threshold configuration;

[0096] 3) release threshold configuration;

[0097] 4) Occupation strategy in release state;

[0098] 5) Application step length;

[0099] 6) Failure holding time.

[0100] B. IP address resource application / release module;

[0101] The IP a...

Abstract

The invention discloses a method, device and system for realizing address sharing. An address pool for unified management of IP addresses is configured on an AAA server; the AAA server can allocate IP addresses for CGN equipment according to the configured address pool. The technology for realizing address sharing in the present invention realizes the sharing of IP address resources between CGN devices, so it can solve the problem of resource load sharing between CGN devices, improve the sharing rate of IP address resources, and realize resource optimization; and in IP Address management provides operators with a more convenient platform. In addition, because the IP address is uniformly managed by the AAA server, there is no need to configure an address pool on the CGN device, so the CGN device can start without an address pool.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing address sharing. Background technique [0002] With the depletion of IPv4 addresses, Network Address Translation (NAT) technology is more and more widely used. However, address resources cannot be dynamically shared among carrier-grade NAT (Carrier Grade NAT, CGN) devices. NAT public network address pools are directly or indirectly configured on devices, which may cause some device address pool resources to be tight, and The phenomenon that some device address pool resources are surplus. [0003] For operators, the total number of IP addresses is limited, and the imbalance between regions and time often leads to sometimes tight and sometimes surplus IP addresses. [0004] For example, places A and B also have N IP addresses. Due to the large-scale activities held in region A, the IP addresses in region A are exhausted, and because the ...
