Efficient Usage of Resources in SDN by Modifying YANG Modules in Linux-based Embedded Systems

In a new paradigm of software-defined networking, NETCONF protocol takes a completely new role. The NETCONF protocol existed before the new paradigm of programmable networks and used in various purposes. In a domain of the programmable network, it is used as a southbound interface. With the YANG (yet another new generation) modeling language, NETCONF protocol has the ability to model configuration data for network elements. The lack of resources in embedded systems forces network developers to minimize data models on the network elements. In this paper the communication between client and server on NETCONF protocol, as well as usage of the YANG models to overcome the resource shortages, are described.
