Emulating Software Defined Network Using Mininet and OpenDaylight Controller Hosted on Amazon Web Services Cloud Platform to Demonstrate a Realistic Programmable Network

Abstract

In this paper, a Software Defined Network was created in Mininet using python script. An external interface was added in the form of an OpenDaylight controller to enable communication with the network outside of Mininet. The OpenDaylight controller was hosted on the Amazon Web Services elastic computing node. This controller is used as a control plane device for the switch within Mininet. The OpenDaylight controller was able to create the flows to facilitate communication between the hosts in Mininet and the webserver in the real-life network. In order to test the network, a real life network in the form of a webserver hosted on the Emulated Virtual Environment-Next Generation (EVE-NG) software was connected to Mininet.

Load balancing using openday light SDN controller: Case study

“…Prior to this universities have had to build their own research sites from scratch before that. [5][6][7][8] Any system that wants to communicate with an SDN controller must be knowing the OpenFlow protocol to work in its domain. The SDN controller push converts into a switch/router flow table via this interface, enabling network administrators to track partition traffic, control flows for optimum performance and check for various different configurations and applications [4].…”

“…Hence, this program is dynamic in nature as it continue to update this information every minute. In this research a test-bed has been implemented under Linux, using Mininet software to emulate the network, the open-source [6] OpenDaylight platform (ODL) as SDN controller, and Python programming language to define the fat-tree topology and to write the load balancing algorithm program, and iPerf to test network performance. The fig.…”

“…Mininet is a network emulator that allows prototyping large networks on a single machine [6]. It runs a collection of end-hosts, switches, routers, and links on a singleLinux kernel.…”

“…The OpenDaylight Project (ODL) [6]is a highly available, modular, extensible, scalable and multiprotocol controller infrastructure built for SDN deployments on modern heterogeneous multivendor networks. ODL provides a model-driven service abstraction platform that allows users to write apps that easily work across a wide variety of hardware and south-bound protocols.…”

Uma Avaliação sobre a Tolerância a Falhas no Plano de Dados em Controladores SDN

“…Em uma rede SDN o controlador executa um papel fundamental. Por este motivo, pode-se observar diversos esforços concentrados no controlador no sentido de avaliar seu desempenho [Zulu et al 2018], torná-lo distribuído [Kohler et al 2018], escalável [Bianco et al 2017, Karakus andDurresi 2017], confiável [Curic et al 2018, Venâncio et al 2018, seguro e tolerante a falhas [Gonzalez et al 2016]. Estes atributos foram ou estão sendo implementados nos diversos controladores disponíveis para uso.…”
