Quality of Service

Quality of Service

Network traffic classification: what it is, how it works, and what classes there are

Modern networks handle many types of traffic simultaneously: video, voice, online games, corporate services, and background downloads. Each of these has its own requirements for connection quality. For example, stable bandwidth is important for streaming video, while minimal latency and jitter are important for voice services. Background file transfers, on the other hand, can be interrupted without serious damage. If all traffic is processed equally, critical services will quickly begin to suffer from overload.

How to Use QoS to Ensure the Internet Access Quality

Not all internet traffic is equally important. An online video without picture freezing or a Skype call without voice stuttering is more critical than downloading a large file using a torrent client. The Quality of Service (QoS) function of a router, shaper, or deep packet inspection (DPI) system allows you to prioritize which traffic is more important and provide it with most of the bandwidth.

Limiting subscribers' data download: QoS and profit

Usually, when we talk about the quality of service (QoS) we describe ways for speed limitation for individual users, applications and protocols by prioritizing traffic. Thereby it allows a rational use of bandwidth and prevents performance degradation.

QoS Management Helps Operators during the Pandemic

Availability and quality of Internet connection are the main indicators Broadband provider’s work.

Ways to effectively allocate bandwidth

In today's world, Internet access is one of the main services provided to users of computers, tablets, smartphones, and other devices. Access speed, in other words, the bandwidth of the channel provided or the data transfer rate, is of great importance in terms of the quality of the service provided.
