Understanding OPNFV 21 on the OSS/BSS layer, which is the layer that improves competitiveness and generates revenue. Example Total-cost-of-ownership (TCO) Analysis Intel and the PA Consulting Group have created a comprehensive TCO analysis tool for the vCPE use case (see below). In one representative study conducted with British Telecom, the tool was populated with assumptions for an enterprise customer where physical network functions from the customer's premise were moved to the operator's cloud. In this study, the tool shows that the operator can reduce their total cost by 32% to 39%. The figure encompassed all costs including hardware, software, data center, staff and communication costs. The TCO analysis was conducted over a five-year period, and included a range of functions such as firewall, router, CGNAT, SBC, VPN and WAN optimization. These results are representative and will obviously change if another study has different assumptions. Also, as mentioned earlier, cost is only one of the many benefits of NFV. One study found 32%-39% TCO reduction for vCPE NFV Use Cases Since the initial group of companies that popularized NFV was made up primarily of telecommunications carriers, it is perhaps no surprise that most of the original use cases are related to that field. As we've discussed, NFV use cases span a broader set of industries. Instead of covering all use cases comprehensively, we are going to touch upon the three most common: vCPE (Virtual Customer Premise Equipment) vCPE virtualizes the set of boxes (such as firewall, router, VPN, NAT, DHCP, IPS/ IDS, PBX, transcoders, WAN optimization and so on) used to connect a business or consumer to the internet, or branch offices to the main office. By virtualizing these functions, operators and enterprises can deploy services rapidly to increase revenue and cut cost by eliminating truck rolls and lengthy manual processes. vCPE also provides an early glimpse into distributed computing where functionality in a centralized cloud can be supplemented with edge compute. vEPC (Virtual Evolved Packet Core) Both the sheer amount of traffic and the number of subscribers using data services has continued
