Abstract

Software Defined Networking (SDN) is an architectural network approach that allows software-based load balancer applications to control, programme and manage the network. SDN separates the network configuration and data traffic from the root hardware infrastructure, to ensure integrated and harmonious control of the network. The SDN enables network behaviour to be programmed in a centralised manner using APIs. Furthermore, users programme, manage the entire network and implement network devices consistency by adopting a common SDN layer while disregarding the complexity of the root network technology in the legacy network. In this project, SDN offers a lot of benefits to find. SDN centralised network provisioning, allowing for enterprise management and provisioning to be centralised. More VLANs, for example, are being created and part of the physical LANs, which produce links of Gordian Knot and dependencies. As a matter of fact, SDN offers benefits such as lower operating cost, administrative efficiency, improvements in server utilization and a better control of virtualization. However, SDN consists of limitations such as security problems and managing load balancing. Security and load balancing are two common problems in SDN since hardware routers and switches have been removed from the network, and security features such as firewalls are no longer available in the network architecture. These limitations and disadvantages of SDN are discussed and examined in this final year project to ensure that SDN offers ways that are widely used in the future. Therefore, the SDN approach is simulated using Mininet, and OpenDayLight to evaluate the characteristics and performance of the security and load balancing to be operated on the network.
