Data is forwarded along the pathway using a best-effort approach.

|
|
Data is forwarded along the pathway using DiffServ.
|
|
|
Data is not forwarded along the pathway.

|
|
Data is forwarded along the pathway using IntServ but not provided preferential treatment.

Detailed explanation-1: -What happens when an edge router using IntServ QoS determines that the data pathway cannot support the level of QoS requested? Data is forwarded along the pathway using IntServ but not provided preferential treatment.
Detailed explanation-2: -There are three models for implementing QoS. QoS is implemented in a network using either IntServ or DiffServ. IntServ provides the highest guarantee of QoS, it is very resource-intensive, and therefore, not easily scalable. DiffServ is less resource-intensive and more scalable.
Detailed explanation-3: -Quality of service (QoS) is the use of mechanisms or technologies that work on a network to control traffic and ensure the performance of critical applications with limited network capacity. It enables organizations to adjust their overall network traffic by prioritizing specific high-performance applications.
