Bandwidth resource allocation method of Internet of Things intelligent gateway

Abstract

The invention discloses a bandwidth resource allocation method of an Internet of Things intelligent gateway, and relates to the technical field of software defined networks (SDN). The bandwidth resource allocation comprises the following steps of: A, constructing a hierarchical network slice architecture; B, adopting an OVS software virtual switch technology carry out internal transformation on awireless AP based on an Openwrt system, wherein a network interface is completely taken over by an ovs network bridge after transformation, and the AP supports an SDN forwarding plane of an openflow protocol; C, acquiring AP end related information, analyzing according to the acquired information, and acquiring a bandwidth resource allocation node according to the network slice architecture. Aiming at scenes of different flow demands and differentiated service quality demands of different services of a wireless local area network, the invention provides a software-defined Internet-of-Things intelligent gateway virtualization bandwidth resource allocation method, so as to realize dynamic scheduling of bandwidth slices and bandwidth resources of an intelligent gateway wireless network.

Description

technical field [0001] The invention relates to the technical field of software-defined network (SDN), in particular to a method for allocating bandwidth resources of an intelligent gateway of the Internet of Things. Background technique [0002] Wi-Fi is a wireless local area network technology based on the IEEE802.11 standard. It can provide users with wireless network access services. Its biggest feature is flexibility and convenience. With the popularity of wireless networks and the rapid increase in the number of wireless terminal devices led by IoT technology, wireless local area networks are favored by more and more users. Not only individual users, but more and more enterprises, schools, governments, etc. are using routers, wireless access points and other equipment to build wireless local area networks. On the one hand, they can improve their work and communication efficiency, and on the other hand, they can also attract and assist customers. [0003] In the tradit...

AI Technical Summary

Problems solved by technology

In the case of a large number of multiple types of user groups accessing at the same time, because different business traffic has different requirements for QoS, there are often problems such as uneven bandwidth allocation, resulting in poor user experience

However, the flow control function of traditional APs can only limit the global bandwidth, which cannot meet the different needs of various user groups in complex access scenarios.
