Embodiment 1

[0105]This embodiment will describe how to use SDN to perform network architecture for wireless networks. Please refer to figure 1 , which is a method flowchart of a network architecture method of the present invention, applied to a wireless network, and the method includes:

[0106] S101: Split the functions implemented by the serving gateway SGW, the public data gateway PGW and the mobility management entity MME in the wireless network;

[0107] What needs to be said here is that the functions mainly refer to the data plane functions that can be completed by the above-mentioned physical devices. Taking PGW as an example, PGW integrates many data plane functions, such as mobile IP, data packet filtering, general data transmission platform ( General Data Transfer Platform, GTP) tunnel management, security and billing, and more. There are many kinds, so I won't list them all here.

[0108] S102: Deploy the split function in a centralized control network element (Single Networ...

Embodiment 2

[0119] This embodiment is a device embodiment corresponding to the first embodiment, and the structure and connection relationship between the devices will be further described. Please refer to figure 2 , which is a device structure diagram of a network architecture device of the present invention, applied to a wireless network, and the device includes a function splitting unit and a deployment unit:

[0120] A function splitting unit 201, configured to split the functions that can be implemented by the serving gateway SGW, the public data gateway PGW and the mobility management entity MME in the wireless network;

[0121] The deploying unit 202 is configured to deploy the split function in the centralized control network element SNC, the data rule matching entity Entry, the distribution entity Distributor, the network address translation NAT, the function node network FNN, and the broadcast node Radio according to the business type of the function. in Node;

[0122] Wherein...

Embodiment 3

[0136] This embodiment will further describe how to reasonably and effectively allocate services to these FNs that are endowed with service functions after implementing the SDN wireless network architecture in which the control layer and the data plane are separated. Please refer to Figure 4 , which is a method flowchart of a service allocation method of the present invention, which is applied to a wireless network of a software-defined network SDN, where the wireless network of the SDN at least includes a broadcast node Radio Node, a centralized control network element SNC and a functional node network FNN.

[0137] The application scenarios need to be explained here. The application basis of the technical solution in this embodiment is a wide range of SDN wireless network architectures that can realize the separation of the control layer and the data plane. Of course, it can also be specifically implemented on the basis of the first embodiment. of.

[0138] The method speci...

Abstract

The present invention provides a network architecture method, and traffic distribution method and related device, comprising: in a wireless network, splitting the functions performed by a PGW, an SGW, and an MME; according to the traffic type of said functions, deploying the split functions in a centralized control network element, a data rule matching entity, a distribution entity, a network address translator, a functional node network, and a broadcast node; it can be seen that decoupling the functions in an MME, PGW, and SGW in a wireless network, splitting the functions from their original physical entities, and deploying the functions to functional nodes (FN) in a functional node network (FNN) allows for the implementation of SDN architecture of a wireless network. An SNC determines the operating states of the FNs by means of monitoring the traffic loads of the FNs in the FNN, and distributes traffic according to different operating states, such that the traffic distribution can be adjusted dynamically according to changes in FN operating state.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network construction method, a service distribution method and related devices. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture proposed by the cleanslate research group of Stanford University in the United States. The main idea of ​​SDN is to separate the control layer from the data All network devices in the network are regarded as managed resources, then the concept of network operating system (Network OS) can be abstracted by referring to the principle of operating system. On the one hand, the network operating system abstracts the specific details of the underlying network devices, and at the same time provides a unified management view and programming interface for upper-layer applications. In this way, based on the network operating system platform, users can develop various a...
