Uma arquitetura para provisão de fatias de rede fim-a-fim em ambientes multi-inquilinos
Resumo
Nos últimos anos, o mundo das telecomunicações experimentou progressos no desenvolvimento de tecnologias de comunicações móveis. O fatiamento de recursos em rede foi identificado como a espinha dorsal das redes móveis de próxima geração, graças à sua rápida evolução. No entanto, ainda existem algumas arquiteturas que permitem aplicar o conceito de fatiamento de recursos na nuvem. O projeto NECOS define e implementa uma arquitetura Slice as a Service para cenários de vários domínios, onde a ideia principal é exercitar o conceito de fatia de rede na nuvem como uma soluçao completa para provisionar serviços de ponta a ponta entre provedores federados. Portanto,o objetivo deste artigo é apresentar a arquitetura NECOS para provimento de fatias de recursos fim a fim, concentrando-se em dois componentes, o DC e o WAN Slice Controller, responsáveis pela alocação de recursos computacionais e de rede nos provedores de infraestrutura. Através dos resultados obtidos, o artigo mostra a viabilidade da arquitetura para fatiamento de recursos.
