Linux software based uplink QoS scheduling method and device

Abstract

The invention discloses a Linux software based uplink QoS (Quality of Service) scheduling method and device, and relates to the field of IP network data transmission. The method comprises the following steps: clustering uplink data of residential gateway equipment to IMQ virtual interface equipment for speed limiting, wherein the flow control and scheduling of data packets are realized, and at the same time, the flow direction of data in the residential gateway is not changed; identifying the characteristics of the data packets at the IMQ virtual interface equipment of an uplink data exit of the residential gateway equipment, placing the data packets in different priority queues according to the corresponding relation of the data packet characteristics and the priority queues; and processing the data packets in the corresponding queue according to an absolute priority strategy by using the priority queues, so as to realize the priority guarantee during data packet forwarding process. According to the method and device based on the Linux software, not only the functions of classifying, scheduling and marking the data packets are realized, but also the uplink QoS scheduling in the residential gateway equipment based on the Linux inner core is realized. In addition, the hardware cost is reduced, and the market competitiveness is improved.

Description

technical field [0001] The invention relates to the field of IP (Internet Protocol, Internet Protocol) network data transmission, in particular to a method and device for realizing uplink QoS (Quality of Service, Quality of Service) scheduling based on Linux (an embedded operating system) software. Background technique [0002] QoS is a security mechanism implemented by network devices to ensure data flow, and is usually used to improve network packet delay and congestion problems. [0003] At present, real-time services such as VoIP (Voice over Internet Protocol, voice telephony based on IP protocol), IPTV (Internet Protocol Television, interactive network television) and other real-time services are more and more widely used in the network. The delay requirement is high. Under normal circumstances, if the network is only used for a specific non-time-limited application system, QoS is not particularly required, such as Web (web page) applications or E-mail (email) settings....

AI Technical Summary

Problems solved by technology

However, at present, gateway devices generally implement the function of QoS guarantee for uplink business traffic by adding additional switching chips and adopting hardware methods, which requires high hardware requirements, resulting in high costs.
