1. 1. Best Practices for vCPE Deployment How to Ensure Optimal Results and Avoid Pitfalls June 2015
2. 2. vCPE Deployment Best Practices 2 What You Will Learn • The State of NFV • What is vCPE? • Implementation Options • Takeaways
3. 3. The State of NFV
4. 4. 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
5. 5. 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) Economics Tradeoff between network and IT costs e.g., for international services Performance Some applications are more effective at the customer premises e.g., end-to-end QoS, response time, survivability in case of access failure Policy Dictated by regulations and policies e.g., information location, access control policy Some functions MUST run at the customer premises e.g., end-to-end encryption and WAN optimization Feasibility
6. 6. What is vCPE?
7. 7. 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)
8. 8. 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:
9. 9. Implementation Options
10. 10. 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 Network TesterFirewall PBX VNFs Customer Site Customer Network Data Center Orchestrator
11. 11. vCPE Deployment Best Practices 11 Distributed NFV • 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 network redesign Scenario B: All VNFs at the Customer Edge Network Customer Site RouterFirewall VNFs PBX Customer Site Router VNFs Firewall PBX Customer Network Orchestrator Customer Network
12. 12. vCPE Deployment Best Practices 12 • 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) Scenario C: VNFs at the Network & Customer Edge Network Tester PBX VNFs Customer Site Customer Network Data Center RouterFirewall VNFs Orchestrator Distributed NFV
13. 13. 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
14. 14. Takeaways
15. 15. 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
16. 16. 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 RAD’s vCPE Offering ETX-2 L2/L3 Demarcation with D-NFV MiNID Miniature Programmable NID RADview Network Management and Orchestration
