Ing. Tomáš Halagan  Today’s network infrastructure  NFV in nutshell  Terms and definitions of NFV  NFV High Level Architecture  Benefits of NFV  Existing NFV solutions  Which is better – SDN or NFV ?  My work  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  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.  We have to simplifying network design, increase agility, speed up deployment of new services.  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  Network Function (NF)  Network Function Set (NF Set  Physical Network Function (PNF) An  Virtualized Network Function (VNF)  Network Function Virtualization Infrastructure (NFVI)  NFV-Resource (NFV-Res)  NF Forwarding Graph  VNF forwarding Graph  NFV Orchestrator OSS / BSS NFV Scope Virtualized Network Functions (VNFs) VNF VNF VNF VNF (End-users, Other Services) NFV Infrastructure (NFVI) Virtual Infrastructure Virtual Computing Virtual Storage Virtual Networking Physical Infrastructure Other Networks Compute Storage Network NFV Management and Orchestration (MANO) Service End-Points  Reduce Capex – reducing purpose-built hardware, supporting pay-as-grow  Reduce Opex – reducing space, power, cooling of equipment  Accelerate Time-to-Market – reducing the time to deploy new networking services  Deliver Agility and Flexibility – scale up or down services, inovation  CloudNFV – taking NFV to the Cloud • Implementing NFV based on cloud computing and SDN in multi-vendor environment. • The network and applications are not just equal, but the same – in the cloud. • Product of cooperation between 6WIND, CIMI, DELL, EnterpriseWeb, Overture Networks and Qomos  Contrail – developed by Juniper • networking solution that automates and orchestrates the creation of highly scalable virtual networks.  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.  Focusing on NFV, SDN and their interconnection  Propose simple plugin to SDN controller, which could be as orchestrator and manages VNFs, NFVIs, their deployment to customers  Use The Best... • Linux for Servers • Mac for Graphics • Palm for Mobility • SDN for networks • NFV for services • Windows for Solitaire
