If you understand network engineering, you probably know that the requirements for networks are growing every year. At the same time, it is consumers who now determine what the network will be like in the future. Because they want not only to use the available resources, but to consume the highest quality content. And if your network does not have enough resources to meet the needs of consumers, then you need to solve this problem as soon as possible. And this can be done with the help of Quality of Service.

What is Quality of Service

Imagine that you have a corporate network under your management. You perform diagnostics and identify the following problems: low data transfer speed, packet loss, traffic delays. Of course, all these problems will significantly affect the quality of work of network users. For example, if the company's employees need access to IP telephony or high-quality video content. As a result, the organization's employees will not be able to effectively perform their work duties. This means that the company will suffer significant losses. It is in such a situation that experienced network engineers recommend implementing QoS tools.

Quality of Service (QoS) is a technology that includes a set of algorithms and mechanisms that are used to process various types of traffic, taking into account their priority on network devices. By implementing QoS tools, it is possible to use available channel resources more efficiently. This is required in conditions of severe resource shortages in modern networks. And also with increasing service and user requirements directly to network services.

Thus, Quality of Service is a powerful tool, the implementation of which allows to provide a given level of quality of service when transmitting types of traffic that are critical to various network characteristics. QoS can be used both in global and corporate networks.

How to learn to configure Quality of Service

First of all, it is worth noting that knowledge on setting up Quality of Service is highly specialized. That is, if you are a novice network engineer who wants to learn more about how networks work, then you should pay attention to Cisco CCNA course. Whereas the course “Quality of Service (QoS): Quality of Service in IP Networks” is more suitable for experienced specialists who want to improve their skills.

During the course you will learn:

• how to set up traffic classification and marking;
• why Traffic Shaping and Traffic Policing are needed;
• what is Queuing / Congestion Management;
• When to use Congestion Avoidance.
