O que é o GENI?

• Laboratório virtual para explorar o futuro da internet.– Entender: Redes globais e suas relações com a

sociedade;– Inovar: Além das fronteiras da ciência e da

engenharia;– Transformar: A pesquisa em redes e a sociedade

como um todo.

Objetivos do GENI

• Suportar pesquisas em escala em uma infraestrutura compartilhada, heterogênea e equipada.

• Permitir uma configuração em “profundidade”, promovendo inovações e novos desenvolvimentos em redes, segurança, tecnologia, serviços e aplicações.

• Prover um ambiente colaborativo para instituições e empresas fomentarem as descobertas e inovações.

Objetivos do GENI

Infraestrutura

• Programável: software para controlar o comportamento dos nós.

• Virtualização: múltiplos pesquisadores utilizando o mesmo equipamento.

• Ecossistema: diferentes recursos operados por diferentes organizações em prol do GENI.

• Fatias: recursos compartilhados e reservados em diversas localizações.

Participantes

• NSF – National Science Foundation• GENI Project Office: BBN Technologies• 83 times (Setor acadêmico e privado)• Parceiros: Internet2, National Lambda Rail• Empresas: AT&T, Arista, Cisco, Fujitsu, HP, IBM,

Microsoft...

Rede GENI

Estrutura

Design GENI

• Subconjuntos (porções) dentro do substrato de rede

• Sem limites na arquitetura de rede• Clean-slate e arquitetura atual

Espirais (fases)

• 1ª espiral: Desenvolvimento dos planos técnicos e operacionais.

• 2ª espiral: Integrar protótipos, estruturas e melhorar arquiteturas, ferramentas e serviços.

• 3ª espiral: Suportar experimentos na rede GENI, aumentar os recursos disponíveis e facilitar a participação, conexão e configuração.
