What is QoS and Why You Should Care

Why QoS is Vital for Application Efficiency

Quality of Service (QoS) is the measurement of the overall performance of a service. In IT circles, this service could be cloud computing, a network, or the performance of a software application. Specifically, we’ll focus on the importance of QoS in enterprise networks.

An optimally functioning network must provide predictable and measurable services as applications access or communicate through the networks. These applications could be voice, video, and sensitive data. It is important to note that organizations make use of QoS to meet the traffic requirements of these applications and prevent quality degradation caused by packet loss. This is the major reason to care about QoS.

  1. Traffic Shaping and Policing – QoS determines the ability of a network to provide better services to a set of users or applications, sometimes at the detriment of other users. This means that in a situation where you need a special set of users to have the best possible service, more bandwidth or resources will be directed to service their traffic. Network service providers and businesses use traffic shaping to keep their high-net worth consumer base happy.
  2. Helps Create and Service Priority Traffic – QoS also involves the detection of different types of network traffic coming from end users. This traffic could be gaming, video or audio traffic. Businesses can use this knowledge to make dynamic routing decisions with the aim of prioritizing the network traffic it deems most important. Therefore, if gaming is more important to your business growth, more network resources will be made available for gaming data types. This is known as a differentiated service model in IT circles.

As far as QoS implementation, it is important to know the two major processes: automatic QoS and manual QoS. Automatic QoS, also known as intelligent QoS, requires minimal setup and configuration when defining traffic priority. Automatic QoS makes automated decisions based on predefined priorities.

Manual QoS is generally configured by a router administrator. He or she will be tasked with configuring priorities. These priorities can be defined according to traffic type and IP addresses. Therefore, an experienced router administrator or network analyst will be required to set up and update the business’s QoS.
