5. Network Quality of Service (QoS) Quality of Service (QoS) refers to the ability of an application to request a guaranteed level of networking service in the form of bandwidth, latency or jitter.

6. Network Quality of Service (QoS) Two well-know types of QoS: Integrated Services (IntServ) Integrated Services (IntServ) Differentiated Services (DiffServ) Differentiated Services (DiffServ)

7. Network Quality of Service (QoS) Misconception for QoS in CVR: Once the QoS is available, it will solve all CVR’s networking problems. Once the QoS is available, it will solve all CVR’s networking problems. Bandwidth provisioning is the only form of QoS needed by CVR applications. Bandwidth provisioning is the only form of QoS needed by CVR applications.
