An application-aware system and method based on software-defined and user-centric networks

Abstract

The invention discloses an application awareness system and method based on software definition and user-centered network, including an access layer application awareness module, a VUC layer application awareness module and an RC layer application awareness module; wherein the access layer application awareness module is deployed in In the base station, the preliminary identification of the application type and the classification of the application traffic are realized; the VUC layer application awareness module is generated centered on the user through software definition, and manages all base stations in the user cell; the RC layer application awareness module is generated through the software The defined form manages the VUC layer application awareness module and controls the global network. Based on the user center, the flexibility is higher, and the overhead of the RC layer and the VUC layer is small, and the access layer is based on the machine learning module to perceive more comprehensive and comprehensive information.

Description

technical field [0001] The invention belongs to the network architecture of a 5G mobile communication system, and in particular relates to a software-defined and user-centric network-based application perception system and method thereof. Background technique [0002] At present, a large number of domestic and foreign research institutions have begun to conduct research on the 5G wireless network architecture. In order to efficiently control the wireless network, the related 5G wireless network architecture research has introduced the idea of ​​software definition to achieve unified control of the wireless network. Research on application-aware technology, one of the key technologies of SDN, is also in full swing. [0003] The University of Minnesota and Bell Labs Alcatel-Lucent jointly proposed an SDN-based application-aware data plane. By deploying the application awareness module of the data plane on the Openflow switch, the localization of application awareness is real...

AI Technical Summary

Problems solved by technology

[0006] First of all, the existing application-aware architecture lacks the ability to cooperatively perceive networks of multiple standards. It senses on the data plane through the switch, and the controller summarizes the perceived application information, and analyzes and identifies the applications that cannot be recognized by the switch.

This architecture cannot distinguish between applications transmitted in networks of different standards

[0007] Secondly, the existing application-aware architecture aggregates all the perceived information to a single controller for analysis and processing, and the signaling overhead and information interaction in the network will occupy a large amount of network resources.

[0008] Finally, the user's personalized service is difficult to achieve

Application perception is based on the flow as a unit and based on the data plane. It is difficult to distinguish the applications generated by each user, especially the application information transmitted by the same user through different standard networks cannot be sensed and aggregated.

At present, most of the existing application perception research focuses on how to improve the accuracy of perception and reduce overhead, while ignoring user-based application perception research, which cannot provide targeted application perception to meet the individual needs of users. information
