Benefits •  Improved experiences for your

customers •  Faster fulfillment times, newer

methods to service ordering •  Deploy new applications and

network services at web speed •  Accelerate your time to revenue •  Cut operational costs significantly

Benefits of NFV approach

NFVI

11 © 2015 Cisco and/or its affiliates. All rights reserved. Cisco Confidential

•  Many entry points •  Replace PNF with VNF •  Use an Orchestration solution to

provision your PNFs •  Implement a NFVI and manually deploy

VNFs •  Build an ETSI like reference architecture

(NFVI, VIM, VNFM, Orchestrator) -- OR --

•  Adopt a pre-packaged ETSI like evolved platform w/ •  + pre-packaged solutions + easy to

use Portal

How do you start this journey?

•  Better customer experience •  Customizable portal

•  Faster time to market •  Significantly reduces in-house integration

time for the base platform

•  Pre-packaged solutions / functions reduces ROI period

•  Focus on business services, rather than underlying stack

Examples of pre-packaged services •  Cloud VPN - Highly secure business

connectivity and routing (VPN) for site-to-site, and remote access

•  Cloud MPLS - Security services delivered over your existing MPLS VPN connectivity

•  Cloud iWAN services – Secure connectivity over flexible transport options, using hybrid WAN (MPLS or Internet) with Dynamic Multi-point VPN overlay

Benefits of adopting an Evolved Platform

Service Fulfillment in the virtual world

•  Automated Business process & rules driven

•  Service provisioning will be through orchestration engines

•  Opportunities to customize and/or create new services

Adoption Challenges •  Solution deployment

(upgrade, new services, etc.) are lot more (near) real-time

•  Integration with OSS/BSS is lot more dynamic

•  Challenges various aspects of current Solution development and Operational processes
