The Economic Benefits of Distributed Broadband Services
Peter Fetterolf's paper The Economic Benefits of Distributed Broadband Services compares the legacy centralized BNG architecture with the spine-leaf design:
- identification of some challenges with legacy centralized BNG architectures,
- details of the new spine-leaf design, and
- assumptions and results of the total cost of ownership (TCO) model.
The analysis compares the legacy centralized BNG architecture with a distributed spine-leaf BNG architecture and shows a five-year TCO savings of 35%. We also present scenarios where both the legacy BNG and the spine-leaf BNG designs are deployed in central office data centers to compare their TCO. These approaches produced the most significant five-year cumulative TCO savings of 64%.
