Implementación de servicios de networking mediante DevOps : implementación de una SD-WAN open source mediante máquinas virtuales y ansible.

Abstract

The increasing volume of data traffic and the need for greater capacity in Wide Area Networks (WANs) present significant challenges. As WAN devices strive for enhanced performance, they often encounter rising costs. This dilemma has spurred the development of technologies such as Software-Defined Networking (SDN) and the virtualization of network functions to overcome the constraints of current devices. To fully comprehend this issue, we must examine the key attributes of expanding WANs, such as efficiency and scalability, which are vital for achieving optimal performance. Although enhancing WAN device performance with specialized hardware is one approach, it can be cost-prohibitive and may introduce other limitations. Innovative solutions like SD-WAN and network virtualization offer promising alternatives. These technologies not only streamline network complexities but also boost bandwidth, performance, and redundancy. They facilitate centralized management and control as well. The principal aim of this thesis project is to implement an open-source SD-WAN using virtual machines and Ansible. Initially, it will involve exploratory research on SDN, open-source SD-WAN solutions, DevOps, Ansible, and virtualization technologies pertinent to SD-WAN implementation. Subsequent to evaluating the performance, characteristics, architecture, benefits, and drawbacks of each component, a comparative analysis will be conducted to select the optimal SD-WAN for integration with DevOps tools like Ansible and virtual machines. The project will culminate in presenting a virtualization design, emphasizing the automation capabilities of Ansible, and demonstrating the results from deploying an SD-WAN on VyOS.
