Dynamic bandwidth allocation method, SDN controller and computer readable storage medium

Abstract

A dynamic bandwidth allocation method for a software-defined network requires wireless access point (AP) and router. First total bandwidth information of the AP and second total bandwidth informationof the router are retrieved. Bandwidth values of the AP and of the router are configured according to the first and second total bandwidth information respectively. On a first client connecting to theAP, it is determined whether there is sufficient bandwidth for the AP and the router according to bandwidth information currently required by the first client, and connection is permitted if there issufficient bandwidth for the AP. Bandwidth values of the AP and of the router are configured as third and fourth values for voice calls according to the bandwidth information currently required by the first client.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a dynamic bandwidth allocation method, an SDN controller and a computer-readable storage medium. Background technique [0002] The 4th generation (4G) long term evolution (Long Term Evolution, LTE) network uses Wi-Fi to achieve the purpose of off-loading in order to meet the increasingly higher bandwidth requirements. [0003] Wi-Fi calling (Calling) does not require any third-party software to make calls when the mobile phone is connected to a Wi-Fi network. The mobile phone that supports Wi-Fi Calling uses the Internet Security Protocol (Internet Protocol Security, IPsec) and the Internet Key Exchange Protocol (Internet Key Exchange, IKE) to send Internet multimedia sub- The system (IP Multimedia Subsystem, IMS) registers to conduct voice calls with remote users. [0004] In the enterprise network environment, in order to improve the call quality of Wi-Fi...
