Embodiment Construction

[0028] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0029] The system and method of NAT (Network Address Translation, Network Address Translation) resource adaptive allocation and conversion of multiple Data Planes based on NFV of the present invention are as follows:

[0030] The system for realizing adaptive allocation and conversion of NAT resources of multiple Data Planes based on NFV is mainly characterized in that the system includes:

[0031] EMS management module, used to configure the corresponding relationship between IPG port and Data Plane;

[0032] The vBras virtual management module is connected with the EMS management module through a gateway interface, and is used for receiving and processing traffic load in DataPlane;

[0033] SDN switch module, is connected with described vBras virtual management module by switch interface, in order to for...

Abstract

The present invention relates to a system for realizing adaptive allocation of NAT resources of multiple Data Planes based on NFV, which includes an EMS management module, a vBras virtual management module, an SDN switch module and an SDN controller module. A method for adaptive allocation and conversion of NAT resources of multiple Data Planes. The system and method for realizing adaptive allocation and conversion of NAT resources of multiple Data Planes based on NFV of this invention can evenly allocate NAT resources according to the number of Data Planes, and at the same time, the allocation process is only processed when the Control Plane plane is initialized, so in When Data Plane processes traffic, it will not affect the speed of establishing NAT session flow tables. Using this system can also dynamically change the number of Data Planes and ensure that no traffic interruption occurs. At the same time, the programming of this method is simple and can be effective Adding it to the actual software engineering project ensures the dynamic expansion of the virtual machine's business capabilities and has a wider range of applications.

Description

technical field [0001] The present invention relates to the field of communications, in particular to the field of network address translation, in particular to a system and method for realizing adaptive allocation and transformation of NAT resources of multiple Data Planes based on NFV. Background technique [0002] At present, the global communication industry has begun to enter a new historical stage, that is, the software-defined network stage. The main technical feature of this stage is the transformation of the network architecture, that is, from a vertical closed architecture to a horizontal open architecture, which is reflected in the separation of network control and forwarding, network Decoupling and virtualization of hardware and software, cloudification of networks and ITization, etc. Representative technologies include SDN, NFV and cloud computing. The advent of this stage provides a powerful weapon for the deepening transformation of the telecom network, which ...
