Description

technical field

[0001] The present invention relates to the technical field of QoS (Quality of Service, quality of service), in particular to a dynamic bandwidth adjustment system and method for realizing gateway QoS guarantee. Background technique

[0002] QoS is a security mechanism of the network and a technology used to solve problems such as network delay and congestion. Among them, the bandwidth speed limit is one aspect of the QoS technology. In the case of network congestion, once a device occupies a large amount of bandwidth, other devices will not be able to use the bandwidth normally. QoS bandwidth speed limit solves this problem: for devices that occupy a large amount of bandwidth resources, set the maximum amount of bandwidth they can use, so that when the total bandwidth is certain, other devices can use bandwidth resources normally. Setting the upper limit of the bandwidth that can be used by each device not only ensures that all devices can enjoy a certain ...

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] see figure 1 As shown, the main application scenario of the embodiment of the present invention is: PC, mobile phone, IAD (Integrated Access Device, integrated access device) and other terminals can be connected to the gateway through various interfaces such as Ethernet and wireless local area network, and the gateway can be connected to the gateway through various interfaces. Access to the telecommunications backbone network with input technologies, such as: GPON (Gigabit-Capable Passive Optical Network, Gigabit Passive Optical Network), Ethernet, WiFi (Wireless Fidelity, wireless compatibility certification), etc. When the network is congested, enable the gateway QoS function.

[0042] see figure 2As shown, the embodiment of the present invention provides a dynamic bandwidth adjustment system for gateway QoS guarantee, inc...
