Virtualized Network Functions (VNF) Orchestration and Network Routing in 5G Communication Network
Nipun Agarwal · 2024
The latest wireless technology, 5G, promises increased network capacity, reduced costs, and improved energy efficiency. To achieve these benefits, businesses and service providers use advanced technologies such as Virtualized Network Functions (VNFs) and Software Defined Networking (SDN) to minimize expenses. This study focuses on the challenge of optimizing virtual network functions and routing data through them to create a seamless service chain. To test this scenario, a network was designed with specific requirements and an optimization problem was formulated to minimize costs while meeting service and cloud provider requirements. Quality of service, network, and topology constraints were considered, including a congestion limit on links. As this is a complex problem, a small-scale network was simulated using MOSEK in MATLAB to obtain optimal results, and a heuristic algorithm was developed and compared to the optimal results.
