Resumo: | Some studies are tackling the integration of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) in different environments (e.g., Cloud Computing and Wide Area Network). The use of NFV technology, along with SDN, will play a significant role in 5G networks, since they allow the network programmability and the fast delivery of new services. Although NFV/SDN architectures have clear potential benefits, they are still at an early stage of development. One of the main challenges is the definition of high-level policies necessary to simplify the configuration of NFV Management and Orchestration (NFV-MANO) operations, such as resource allocation and optimization mechanisms, and to meet the customers’ requirements. In this thesis, we intend to tackle part of this problem, namely, issues in the policy refinement procedures. We present the problem for the creation of a policy refinement procedure for NFV systems, as well as the requirements that we consider necessary for their composition. In this sense, we point out the need to have an approach that provides a functional solution for automated policy refinement in policy-based NFV management and orchestration systems. Such a method must support several features such as goal-oriented refinement and detection and resolution of policy conflicts. In this context, we propose the AuTomated POlicy Refinement SysteM for NFV (ATOM), an automated solution for the policy refinement process for Policy-Based Management Systems (PBM) in NFV scenarios (NFV-PBM). To achieve its goal, the ATOM comprises 3 functional blocks: NSChecker, NSPlanner, and Feedback Module. The NSChecker is a semantic verification system to find inconsistencies among policies defined in NS Request (NS-Req) and global policies previously created in the NFVI, i.e., application-specific policies. The NSPlanner provides a solution that enables NFV-MANO to record high-level goals extracted from Network Service Descriptor (NSD) and perform a fully automated policy refinement, that derives enforceable policies (Event-Condition-Action or ECA rules) to govern NFV-MANO behavioral choices while satisfying the goals. Besides, NSPlanner performs policy analysis between management-specific policies, i.e., rules that will be generated by the refinement process and stored in NFV-PBM to govern system behavior. Finally, the Feedback Module is a monitoring system that aims to assist the operator in the task of verifying if the enforceable policies are fulfilling the high-level goals. We conducted a performance evaluation of both NSChecker and NSPlanner. The results demonstrate that NSChecker is efficient even in scenarios with 50,000 NFV Infrastructure Nodes (NFVI-Nodes), while NSPlanner is efficient even in scenarios with 1000 goals and 1000 alarms pre-registered. |

O uso da tecnologia NFV, juntamente com SDN, terá uma função significante nas redes 5G, desde que elas permitem a programabilidade da rede e a rápida entrega de novos serviços. Embora as arquiteturas NFV/SDN tenham claros benefícios, elas ainda estão em um estágio inicial de desenvolvimento. Um dos principais desafios consiste na definição de políticas de alto nível para simplificar a configuração do NFV Management and Orchestration (NFV-MANO), tal como a alocação de recursos e a otimização de mecanismos. Nesta Tese, nós atacamos esse problema, conhecido como refinamento de políticas. Nós apresentamos o problema para a criação do procedimento de refinamento de políticas para NFV, bem como os requisitos que nós consideramos necessários para a sua composição. Neste sentido, nós apontamos a necessidade de se ter uma abordagem que proponha uma solução funcional para o refinamento de políticas automatizado para o NFV-MANO. Tal método deve suportar diversas ferramentas, tais como refinamento orientado à objetivos e a detecção e resolução de conflito entre políticas. Neste contexto, nós propomos o AuTomated POlicy Refinement SysteM for NFV (ATOM), uma solução automatizada para o processo de refinamento de políticas para Policy-Based Management Systems (PBM) em NFV (NFV-PBM). Para alcançar este objetivo, o ATOM é composto por 3 blocos funcionais: NSChecker, NSPlanner e Feedback Module. O NSChecker é um sistema de verificação semântica para encontrar possíveis inconsistências entre políticas definidas no NS Request (NS-Req) e políticas globais previamente criadas no NFVI, ou seja, políticas da aplicação. O NSPlanner provê uma solução que habilita o NFVMANO a registrar objetivos de alto nível, extraídos do Network Service Descriptor (NSD), e realizar o refinamento de políticas. Neste caso, ele deriva políticas executáveis (regras Event-Condition-Action ou ECA) para governar o comportamento do NFV-MANO enquanto satisfaz os objetivos. Além disso, o NSPlanner realiza a análise de políticas entre políticas de gerenciamento, ou seja, regras que foram geradas pelo processo de refinamento e armazenadas no NFV-PBM para governar o comportamento do sistema. Finalmente, o Feedback Module é um sistema de monitoramento que tem por objetivo auxiliar o operador na tarefa de verificar se as políticas executáveis estão satisfazendo os objetivos de alto nível. Nós conduzimos uma avaliação de desempenho tanto do NSChecker como do NSPlanner. Os resultados demonstraram que o NSChecker é eficiente mesmo em cenários com 50.000 NFV Infrastructure Nodes (NFVI-Nodes), enquanto o NSPlanner é eficiente m cenários com 1000 objetivos e 1000 alarmes previamente cadastrados.porUniversidade Federal de PernambucoPrograma de Pos Graduacao em Ciencia da ComputacaoUFPEBrasilAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessRedes de computadoresOntologiaA solution for goal-oriented policy refinement in NFV manegement and orchestration systemsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisdoutoradoreponame:Repositório Institucional da UFPEinstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPECC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

Some studies are tackling the integration of Network Function Virtualization (NFV) and Software-Defined Networking (SDN) in different environments (e.g., Cloud Computing and Wide Area Network). The use of NFV technology, along with SDN, will play a significant role in 5G networks, since they allow the network programmability and the fast delivery of new services. Although NFV/SDN architectures have clear potential benefits, they are still at an early stage of development. One of the main challenges is the definition of high-level policies necessary to simplify the configuration of NFV Management and Orchestration (NFV-MANO) operations, such as resource allocation and optimization mechanisms, and to meet the customers’ requirements. In this thesis, we intend to tackle part of this problem, namely, issues in the policy refinement procedures. We present the problem for the creation of a policy refinement procedure for NFV systems, as well as the requirements that we consider necessary for their composition. In this sense, we point out the need to have an approach that provides a functional solution for automated policy refinement in policy-based NFV management and orchestration systems. Such a method must support several features such as goal-oriented refinement and detection and resolution of policy conflicts. In this context, we propose the AuTomated POlicy Refinement SysteM for NFV (ATOM), an automated solution for the policy refinement process for Policy-Based Management Systems (PBM) in NFV scenarios (NFV-PBM).
