The Trade-offs between QoS and QoE
QoS and QoE are both important goals for network service providers and customers, but they are not always aligned or achievable at the same time. There are trade-offs between QoS and QoE that need to be considered and balanced, depending on the network conditions, resources, and objectives. For example, providing a high QoS for all network services or users may be costly, inefficient, or impractical, and may not lead to a high QoE for all of them. Conversely, providing a high QoE for all network services or users may be subjective, unpredictable, or incompatible, and may not require a high QoS for all of them. Therefore, network service providers and customers need to understand the differences and similarities between QoS and QoE, and how they are affected by various factors, such as bandwidth allocation and reservation, to optimize their network performance and satisfaction.
- In a customer centric org., high QOE could be the ultimate goal which leads more revenue, and to acheive that a better QoS strategy and solution with balanced ROI is the key
