Problem statement: This study addressed the users perceived quality of service requirements in content distribution and investigated the role of QoS. Aware Dominating set based Semantic Overlay Network (QADSON) in surrogate server selection to achieve the specified quality of service. Approach: At first, we constructed the QoS aware dominating set based semantic overlay network which was a virtual network of surrogate servers that was built on top of existing physical network with the purpose to implement new network services and features such as efficiency, exact-1 domination, controlled redundancy and fault tolerance that are not available in the existing network. We applied EFRRA content replication algorithm to disseminate the content among the surrogate servers and evaluated its performance in QADSON. Results: We assessed the efficiency, exact-1 domination, controlled redundancy and fault resiliency of QADSON in terms of mean response time, mean CDN utility, hit ratio percentage, rejection rate and CDN load. We extended the simulation experiments to analyze the role of QADSON in maintaining uniform CDN utility of above 0.95. Conclusion: We also investigated the quality of service requirements for the content distribution and evaluated performance of QADSON based CDN in terms of mean response time, latency, hit ratio percentage, mean CDN utility, rejection rate and CDN load
