Ultimate purposes of technological evolution:
(1) Save money: less spending in deployment and operation;
(2) Make money: discover new revenue stream (VNFaaS)

Conclusion
Top NFV/SDN Use Case in Operators’ Networks: vCPE
vCPE is implementing with many strategies◦Distributed vCPE
◦ vCPE on Aggregation SW or PE Router
◦ Centralized vCPE
=> There is also Hybrid mode which combines Centralized with Distributed vCPE => new trend
