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