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

• 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
