vCPE Deployment Best Practices 2
What You Will Learn
• The State of NFV
• What is vCPE?
• Implementation Options
• Takeaways
vCPE Deployment Best Practices 4
• CSPs need automated & speedy service delivery, with a lucrative cost structure– Requires agile, efficient and well-orchestrated networks
• NFV and SDN move from theory to practice at an accelerated pace– Field trials in 2015– Mass deployments from 2016
Programmable Networks are a Must
Top rated NFV use case among service providers: virtual CPE (vCPE) for business services
Infonetics Research Survey, 2014
vCPE Deployment Best Practices 5
• D-NFV places virtualized networking functions (VNFs) wherever it makes the most functional and economic sense– At the data center, POP and at the customer edge
Distributed NFV (D-NFV)
EconomicsTradeoff between network
and IT costse.g., for international services
PerformanceSome applications are more effective at the customer premises
e.g., end-to-end QoS, response time, survivability in case of access failure
PolicyDictated by regulations
and policiese.g., information location,
access control policy
Some functions MUST run at the customer
premisese.g., end-to-end encryption
and WAN optimization
Feasibility
vCPE Deployment Best Practices 7
• Then: many single-purpose, hardware-based devices (router, load balancer, firewall, etc.)
• Now: virtualized appliances dynamically added or dropped as needed
• Some or all CPE networking functionality is virtualized & relocated
A New Approach to CPE (Customer Premises Equipment)
vCPE Deployment Best Practices 8
Market Drivers
• Fast introduction of new services• No forklifts at the customer’s• Fast response to competition• Value-added services at a premium• Improve QoE to reduce churn
• Simplify operations, management• Lower costs due to truck rolls• Single device: less power and
space, better reliability• Cost-effective new technologies
Conventional appliance-based CPEs:• Mass quantities, CapEx- and OpEx-intensive• Slow and expensive to deploy and maintain• Difficult to roll out new services quickly
NFV-enabled vCPE:
vCPE Deployment Best Practices 10
• All virtualized functions reside at the data center• Basic switch/router as the pCPE at the customer premises• Fits SME services
Scenario A: All VNFs are in the Network

DistributedNFV
• NID w/integrated x86 to host VNFs, or• Colocated standard server + NID
– No traffic offload for faster hardware processing• Fits value-added services (e.g., international business services)• Fits early NFV deployments – no need for full scale

• VNFs placed to optimize cost, performance, policy compliance • Fits value-added services with high networking costs and stringent
performance needs (e.g., international business services)

vCPE Deployment Best Practices 13
• Bandwidth efficiency • Security• Survivability• Performance• Diagnostics and real QoE
What Might be Affected?
Function location should ensure:• Maximum flexibility• Agility• Effective performance
vCPE Deployment Best Practices 15
• vCPE is a prime candidate for first commercial NFV deployments– Especially in business services
• Sweet spot for SPs: hardware abstraction, shorter & flexible service introduction
• VNF placement in vCPE architecture: data center, customer edge, both
• Function location affects:– Efficiency– Security– Survivability– Performance– Diagnostics and QoE
Conclusion
vCPE Deployment Best Practices 16
• Award-winning D-NFV-enabled networking devices, part of RAD’s Service Assured Access (SAA) solutions
• Support any vCPE implementation scenario
• Special VFs for central locations:– Service demarcation and traffic monitoring– VFs for VAS, such as application awareness
• RAD’s D-NFV Alliance offers 3rd-party applications, tested and approved by RAD
