Simulation Analysis of Characteristics and Application of Software-Defined Networks

Software-defined network (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of higher-level functionality. This research includes comparison of multiple scenarios of the software-defined network, which are based on different types of coverage and local area networks (LAN), i.e. a traditional LAN. Differences are evident in the scenario of network performance and can be perceived as advantages and disadvantages of SDN in relation to the traditional network. The parameters used in the analysis are data rate, packet delay (i.e. latency), packet loss, throughput, the cost of network performance and others. The application and the simulation demonstration of a software-defined network is shown in the graphical network simulator GNS and emulator Mininet. This research has analysed the advantages and disadvantages of a software-defined network over a conventional network, taking into account various parameters and stakeholders.
