Abstract
With the continuous expansion of data center services and the aging of equipment, there is a growing need to enhance network services and development. Despite their widespread use, traditional IP networks exhibit limitations in terms of network management efficiency and cost-effectiveness, presenting challenges in configuring networks according to established protocols and promptly addressing changes in traffic load and network issues. Adding complexity, current networks often have a vertically integrated structure.
To address these issues, an emerging concept known as Software Defined Networking (SDN) has gained traction in network design and administration. SDN offers the ability to dynamically allocate network resources, contrasting with the limitations of conventional approaches. This paper delves into the performance challenges faced by existing national data center networks and demonstrates the potential improvements that can be achieved through the adoption of Software Defined Networking (SDN). Additionally, the study employs a modeling methodology to assess the value of these network enhancements, considering various factors such as capital and operational expenses and overall ownership costs in the two scenarios. The techno-economic assessment (TEA) model, implemented using tools like Mininet, Observium, and MS Excel, comprises dedicated sections for cost benefit modeling.
The integration of Software-Defined Networking in Ethiopia's national data center is a strategic move that aligns both with social and economic benefits. The consideration of downtime costs adds a crucial dimension to its implementation. From a social standpoint, the adoption of SDN reflects the government's commitment to enhanced public service delivery and inclusivity. By optimizing network performance, SDN enables citizens to access crucial services efficiently, fostering a sense of equal opportunity. This technological advancement supports good governance by enabling effective resource allocation and timely service provision, ultimately enhancing the trust citizens have in the government's dedication to meeting their needs. The paper thus emphasizes the significant potential of SDN adoption for bolstering both technical and social aspects of national data center networks.
