Introduction to QoS and QoS Mechanisms Course Introduction
Introduction to QoS
As user applications continue to drive network growth and evolution, the demand to support various types of traffic is also increasing. Network traffic from business-critical and delay-sensitive applications must be serviced with priority and protected from other types of traffic. Quality of service (QoS) is a crucial element of any administrative policy that mandates how to handle application traffic on a network. QoS and its implementations in a converged network are complex and create many challenges for network administrators and architects. Many QoS building blocks or features operate at different parts of a network to create an end-to-end QoS system. Managing how these building blocks are assembled and how different QoS features are used can be a difficult task.
