Software-defined networking (SDN) represents a new structure of computer network that simplifies and improves network management by splitting the control plane and data plane. Since SDN is regarded as a new research issue, the application of SDN in practice faces some barriers. Most network devices such as routers and switches that implement SDN functionalities are expensive. An alternative solution in SDN research and experiments is to use network emulators. By using Mininet, an open source network emulator, this study simulates SDN implementations in different environments. Results show that the simulation environment affects building network topology time. | DALAT UNIVERSITY JOURNAL OF SCIENCE Volume 11 Issue 1 2021 80-92 EMULATION OF SOFTWARE-DEFINED NETWORK USING MININET Do Van Khoaa Tran Ngo Nhu Khanha a The Faculty of Information Technology Dalat University Lam Dong Vietnam Corresponding author Email khoadv@ Article history Received February 20th 2020 Received in revised form October 4th 2020 Accepted December 29th 2020 Available online February 5th 2020 Abstract Software-defined networking SDN represents a new structure of computer network that simplifies and improves network management by splitting the control plane and data plane.

INTRODUCTION The vigorous growth of the internet and information communication technology along with novel technologies such as mobile cloud computing big data and the rapidly increasing demand for digital transformation require a proportional development of infrastructure for bandwidth convenient access and flexible management Masoudi amp Ghaffari 2016 . Expansion of network infrastructure to meet these requirements will probably make management and configuration tasks more complicated and time- consuming Xia et al. 2015 . Software-defined .
