Introduction Open Daylight was introduced as a part of the effort of the Linux Foundation to create an open-sourced SDN platform to satisfy the current requirements of modern networking. It was inaugurated in 2013 and since then grew to be one of the most employed SDN controllers in different sectors: providers of communication services, cloud applications and corporate environments. Architecture of Open Daylight At the core, OpenDaylight is designed around a Model Driven Service Abstraction Layer (MD-SAL). This abstraction layer helps in interaction between the SDN applications and the network devices underneath regardless of who the device is manufactured by. In this way the MD-SAL architecture allows the northbound and southbound communications to be designed to operate independently under the SDN environment hence achieving scalability and flexibility. Dealing with a southbound interface This comprises of a system that performs communication with...
