Description: The Graded Service is a quality of service model that allows for different levels of attention and resources to be offered to different types of traffic in a network. This approach is based on the premise that not all data or applications require the same level of service, which optimizes the use of available resources. In this model, applications and traffic are classified into categories that may include, for example, voice, video, and data, each with its own needs for latency, bandwidth, and reliability. This means that, for instance, voice calls may receive priority over file transfers, thus ensuring a smoother and more efficient user experience. The main characteristics of Graded Service include the ability to manage traffic dynamically, the allocation of resources based on demand, and the implementation of policies that ensure that agreed service levels are met. This approach is especially relevant in environments where network congestion can affect the quality of user experience, such as in mobile networks or multimedia content streaming. In summary, Graded Service is a key strategy to ensure that different types of traffic receive appropriate treatment, thereby improving efficiency and user satisfaction in complex network environments.
