Integration of virtual network functions and physical network functions

Integration of virtual network functions and physical network functions

Abstract

A Virtualização de Funções de Rede e as Redes Definidas por Software têm estado no centro da evolução das redes, prometendo uma forma mais flexível e eficiente de as gerenciar através da instanciação on-demand de Funções de Rede e da sua reconfiguração conforme o necessário. No entanto, à medida que novos mecanismos são desenvolvidos, é também necessário a realização de testes sobre estas tecnologias antes destas serem adotadas em implementações em contexto real. É aqui que esta dissertação contribui, propondo e avaliando uma arquitetura de sistema que integra um testbed físico sem fios, com um ambiente baseado em nuvem. Isto permite que os nós sem fios físicos se tornem parte do ambiente de nuvem, permitindo o seu uso e configuração como Funções de Rede Virtuais. Os resultados demonstraram a viabilidade do sistema, dada a capacidade da testbed em instanciar Funções de Rede virtuais e físicas quando requisitadas tanto nos nós sem fios físicos quanto no servidor OpenStack.

Network Functions Virtualization (NFV) and Software Defined Networking (SDN) have been in the center of network evolution, promising a more flexible and efficient way of managing networks through the on-demand instantiation of network functions (NFs) and reconfigurability of the network as necessary. Nevertheless, as new mechanisms are developed, such technologies require testing before their adoption into real-world deployments. This is where this dissertation contributes, by proposing and evaluating a system architecture that integrates a physical wireless testbed with a cloud-based environment. This allows physical wireless nodes to become part of the cloud environment, enabling its use and configuration as virtual NFs (VNFs). Results showcased the system feasibility, with the testbed being able to instantiate on-demand virtual and physical NFs, in the physical wireless nodes and in an OpenStack data-center.
