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...

Abstract

The invention discloses a dynamic bandwidth adjustment system and method for realizing gateway QoS guarantee, and relates to the technical field of QoS. The system includes a CPU, a packet filtering system kernel space component netfilter, a packet filtering system user space component iptables, and a gateway LAN side access device And the ARP module, the speed-limited interface is set in the CPU, the CPU, the packet filtering system user space component iptables, and the gateway LAN side access device are all connected to the packet filtering system kernel space component netfilter, and the gateway LAN side access device is also connected to the ARP module. The invention can realize the dynamic bandwidth adjustment, make the device use the bandwidth to the greatest extent, and effectively improve the utilization rate of network resources in the gateway QoS mode.

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 ...
