Business Case for a Common NFV Platform
The potential of NFV to improve service agility and reduce total cost of ownership requires an approach that allocates hardware, software, and human resources to meet the requirements for all services in an on-demand approach.
ACG Research has written a whitepaper, which was sponsored by VMWare and Affirmed Networks, that explores two emerging models of NFV deployment: 1) custom software stacks that aim to integrate as much of the model as possible into a single solution by a vendor and 2) a modular approach based on the deployment of a common virtualization platform where multiple VNFs and other NFV components are provided independently. The analysis evaluates each approach by comparing its TCO to the TCO of the traditional (appliance-based) approach where all approaches are serving identical functional requirements demand. The analysis determines that only one of these approaches will result in sustainable benefits to the operator.
