Resumo: | The Fifth Generations of Mobile Networks (5G), driven by the aim to further connect today’s society, will have to make use of new emerging technologies such as Software Defined Networking (SDN) and Network Functions Virtulization (NFV) to cope with all the increasing traffic and services that are arising. Critical and Reliable services will make use of these technologies to create new mechanisms and/or to instantiate network functions that have very strict requirements in virtualized environments. The use of these Virtual Network Functions (VNFs) presents several advantages like fast re-instantiation in case of failure or scaling capabilities that are provided by nowadays Cloud infrastructures. In this thesis a study is made comparing the performance of Containers and lightweight Virtual Machines (Unikernels) for the instantiation of a network function in a virtualized environment with restricted resources. It is also implemented a mechanism to ensure the reliability of the VNF. Results show that Containers perform better in the use-case presented and the proposed reliability mechanisms ensure zero downtime for the VNF in case of failure. |

Os serviços Críticos e Fiáveis irão fazer uso destas tecnologias para criar novos mecanismos e/ou instanciar funções de rede que tenham requisitos muito rigorosos em ambientes virtualizados. O uso destas Funções de Rede Virtuais (VNFs) apresenta várias vantagens, como a rápida re-instanciação em caso de falhas ou a capacidade de serem escaladas nos serviços de Cloud fornecidos hoje em dia. Nesta dissertação é feito um estudo em que se compara o desempenho dos Containers e Máquinas Virtuais leves (Unikernels) para a instanciação de uma função de rede num ambiente virtualizado com recursos restritos. Também é implementado um mecanismo para garantir a fiabilidade da VNF. Os resultados demonstram que os Containers têm um melhor desempenho no caso de estudo apresentado e que os mecanismos de fiabilidade propostos asseguram a contínua actividade da VNF em caso de falha.2019-05-03T18:21:13Z2018-01-01T00:00:00Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/25911TID:202242307engFilipe, João Miguel Barracainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:50:12Zoai:ria.ua.pt:10773/25911Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T02:59:02.947495Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |

The use of these Virtual Network Functions (VNFs) presents several advantages like fast re-instantiation in case of failure or scaling capabilities that are provided by nowadays Cloud infrastructures. In this thesis a study is made comparing the performance of Containers and lightweight Virtual Machines (Unikernels) for the instantiation of a network function in a virtualized environment with restricted resources. It is also implemented a mechanism to ensure the reliability of the VNF. Results show that Containers perform better in the use-case presented and the proposed reliability mechanisms ensure zero downtime for the VNF in case of failure. |
