Quality of Services (QoS) in Linux Operating System
Keywords:
QoS, Linux, traffic control, differentiated services, Diffserv, network emulator, Netem module, Traffic Control (TC)Abstract
Quality of Service (QoS) is a fundamental characteristic of contemporary computer networks, enabling the prioritization of network traffic and the allocation of network resources according to specific criteria. The Linux operating system provides a powerful set of QoS tools, including Traffic Control, Differentiated Services, and Network Emulator. These utilities enable you to establish traffic categories, impose bandwidth constraints, and give precedence to traffic according to diverse criteria such as IP address, port number, protocol, and packet size. In addition, the Netem module allows you to emulate various network conditions for testing and debugging network applications and services. In summary, Quality of Service (QoS) functionalities within Linux offer a versatile and effective system for overseeing network traffic, guaranteeing that essential applications and services obtain the required bandwidth and resources for optimal operation.
