Quality of service is a process of using technology to work on a network to control traffic and ensure the performance of crucial applications but with total network capacity. This will help companies alter their overall network traffic by prioritizing particular high-performance applications. It is used with networks that carry traffic for resource-intensive systems. These services use the quality of service: Online gaming, Voice over IP, Streaming media, Internet protocol television, and more.

It will also help organizations enhance various applications’ performance and work on their network’s bit rate and delay. And also the packet rate. It will avoid delays in transmission and route to the internet. This will help the company to achieve predictable service quality applications and provide good user experiences.

How Does Quality of Service Work?

Quality of service is a technology that will mark packets to identify service types and then configure routers to create separate virtual queues for each application based on priority. Because of this, bandwidth is reserved for crucial applications that have been assigned priority access.

This also provides the capacity and workload of allocation to a particular flow in network traffic. It will help the network administrator to assign the order in which packets are handled and give the appropriate amount of bandwidth to each application of traffic flow. This will help to provide the customer packet in order from one point to another through the internet without any packet loss.


Quality of service is essential for many businesses to ensure their critical applications are available. It is also necessary to provide the bandwidth that is distinguishing. And data transmission will take place without causing any interruption in the traffic flow. Apart from it also help in enabling administrators to manage the organization’s internet resources. This process will help cut costs and avoid investments in link expansions.
