Abstract(s)
O projeto aqui apresentado, consiste na implementação de um mecanismo de automatização e manipulação de instanciação de serviços numa rede de operadora, em ambiente de virtualização.
Como objetivos, definiu-se a automatização da instanciação dos serviços de rede Epipe (Ethernet Virtual Private Wire Service), VPLS (Virtual Private LAN Service) e VPRN (Virtual Private Routed Network).
Para tal, foi necessário definir uma arquitetura baseada numa rede IP/MPLS(Internet Protocol/ Multi Protocol Label Switching), utilizando equipamentos Nokia Service Router 7750 na versão virtual, onde foram manipulados com o software GNS3.
Para a manipulação de serviços de rede, recorreu-se ao protocolo NETCONF, linguagem YANG (Yet Another Next Generation), e para a automatização, a ferramenta Ansible. Mais concretamente, foram utilizados os módulos netconf_config, sros_config e netconf_get do Ansible.
Como resultados obtidos, conseguiu-se instanciar e automatizar os serviços de rede definidos nos objetivos, através de uma rede IP/MPLS constituída por vários equipamentos de rede Nokia, um servidor Linux e também vários equipamentos terminais a simular o lado do cliente.
Conclui-se que é possível a automatização de serviços de rede nos equipamentos Nokia, utilizando a ferramenta Ansible e protocolo NETCONF.
The project presented here, consists in the implementation of an automation mechanism and manipulation of service instantiation in a carrier network, in a virtualization environment. As objectives, we defined the automation and instantiation of the Epipe (Ethernet Virtual Private Wire Service), VPLS (Virtual Private LAN Service) and VPRN (Virtual Private Routed Network) network services. To do this, it was necessary to define an architecture based on an IP/MPLS (Internet Protocol/ Multi-Protocol Label Switching) network, using Nokia Service Router 7750 devices in its virtual version, where they were manipulated with the software GNS3. For the manipulation of network services, we resorted to the NETCONF protocol, YANG language, and for automation, the Ansible tool. The netconf_config, sros_config and netconf_get modules of Ansible were used. As results obtained, we managed to instantiate and automate the network services defined in the objectives, through an IP/MPLS network consisting of several Nokia network equipment, a Linux server and several terminal equipment to simulate the side of Client. It is concluded that it is possible to automate network services in Nokia devices, using the Ansible tool and NETCONF protocol.
