  3. Today’s network infrastructure • Diverse network functions (NF). • Providing desired overall functionality or service. • Adding new services • New service instances take weeks to activate • New service types may take months up to years • New service types require either new equipment or upgrading of existing equipment

  4. Today’s network infrastructure Cisco thinks about 50 billion devices will be connected by 2020, after coming out with an earlier analysis in January that claimed 8.7 billion connected devices in 2012. Wehave to simplifyingnetworkdesign, increase agility, speedupdeploymentof new services.

  5. What is NFV ? NFV – Network Functions Virtualization Likewise VM Virtualization – NF and part of the infrastructure is implemented as a software. Result – from dedicated proprietary appliance to COTS hardware

  6. NFV in nutshell

  7. NFV in nutshell

  8. Terms and definition ofNFV Network Function (NF) Network Function Set (NF Set Physical Network Function (PNF) An Virtualized Network Function (VNF) Network Function Virtualization Infrastructure (NFVI)

  9. Terms and definition of NFV NFV-Resource (NFV-Res) NF Forwarding Graph VNF forwarding Graph NFV Orchestrator

  10. NFV HighLevelArchitecture OSS / BSS NFV Scope NFV Management and Orchestration(MANO) Virtualized Network Functions (VNFs) VNF VNF VNF VNF Service End-Points(End-users, Other Services) NFV Infrastructure (NFVI) Virtual Infrastructure Virtual Computing Virtual Networking Virtual Storage Physical Infrastructure Other Networks Storage Compute Network

  11. Benefits of NFV ReduceCapex – reducingpurpose-built hardware, supportingpay-as-grow ReduceOpex – reducingspace, power, coolingofequipment AccelerateTime-to-Market – reducingthetime to deploy new networkingservices Deliver Agility and Flexibility – scaleup or downservices, inovation

  12. Existing NFV solutions • CloudNFV – taking NFV to theCloud • Implementing NFV based on cloudcomputing and SDN in multi-vendorenvironment. • Thenetwork and applications are not just equal, butthesame – in thecloud. • Productofcooperationbetween 6WIND, CIMI, DELL, EnterpriseWeb, OvertureNetworks and Qomos • Contrail – developed by Juniper • networkingsolutionthatautomates and orchestratesthecreationofhighlyscalablevirtualnetworks. • Cisco ONE • offers the broadest approach to open, programmable networks, including SDN controllers, open APIs, and virtual network infrastructures across a variety of deployment models.
