| dc.description.abstract | In this digital age, newly emerged network services and applications have made a huge demand for network performance. A large amount of traffic being generated from this very fastgrowing rate of network traffic has made traditional network technologies reach their limit of capabilities. This huge traffic often causes frequent link congestions, and imbalanced traffic loads and network performance degradation issues on traditional Data Center Networks (DCN) services. To mitigate these increasing demands and challenges, there have been numerous Information Technology (IT) temporary solutions developments in the past decade which do not fix the necessity of modern network problems. So that creative and effective methods of handling multiple applications and services with flexible traffic management and control mechanisms are still needed. In this study, Software Defined Networking (SDN) is used to improve the performance of network services, applications and systems as a whole. The traffic needs to be analysed by identifying network patter. From the test results, we can conclude that using the proposed new architecture, Software Defined Networking (SDN) on existing Internet subscriptions, it is possible to achieve an average response time for Mail service 111.3ms, Web service is 99.7ms, for social media applications 110.5ms and for VoIP applications 113.62ms. The cumulative response time for SDN-based DCN for Internet services and applications is 108.78ms, which has 32.22ms relative improvement and with better throughput for all network traffic being transmitted in typical DCN.
