Evolução das Redes: A Era das Redes Programáveis

ENTERING A NEW ERA IN THE SP NETWORK EVOLUTION

IP unleashes new wave of innovation and service revenues

Discontinuity #1:TDM limits new services, forces architectural shift

Discontinuity #2:Commoditization of IP services plus high traffic growth limits profitability, forces architectural shift

SDN e NFV: diferenças e similaridades técnicas

Function/location separation

Initial focus on atomic network functions, but topology focus

coming

Reduced power usage(elasticity/scalability)

Control/ data plane separation

Focus on network function connectivity (logical topologies)

COTS hardware

Vendor-independence

Rapid service innovation

Improved operational efficiency

Standardized, open interfaces

Dynamic changing of network functions

Centralized orchestration and management

Consistent policy

SDN e NFV: Benefícios

SDN Software Defined Networking Modificar o comportamento da rede (customização da rede) Otimizar a rede para o funcionamento de aplicações de negócio Programabilidade

NFV Network Function Virtualization Melhorar a elasticidade de recursos Reduzir os custos de serviços de rede Virtualização

Benefícios em comum Flexibilidade para novas estruturas e novos serviços Redução no custo de infra de rede Habilitar novas aplicações
