Vendor Independent SDN Architecture Solution

The evolution of mobile communication and its integration into our daily lives has led to a rapid increase in user data and new service innovations. The emergence of two new concepts Software Defined Network (SDN) and Network Function Virtualization (NFV) has radically changed the evolution of network functions and the architectures. While these concepts are considered as drivers for designing low-cost cloud network architectures, limited attention paid to architectural designs based on the harmony between and within the network layers that do not create vendor dependency for the system to operate end-to-end. Open-source standards have been published to ensure interoperability, but the standards do not contain details for each use case. SDN solutions developed by vendors are designed for commercial purposes, and these architectures are wholly or partly vendor dependent. Telecommunication companies are entering a vicious circle in their architectural designs. With 5G Technology offering more bandwidth, high demand of IoT (Internet of Things) increased the pressure of this vicious circle of telecommunication companies. In this paper, SDN Confederation architecture, which solves vendor dependence, is exemplified with Representational State Transfer Application Protocol Interface (REST API) and OpenFlow Experimenter messages working in harmony between and within the layers are presented.
