Peter Fetterolf's paper presents an in-depth economic and environmental comparison between Juniper's MX and PTX Series Routers and those from a leading competitor, focusing on key metrics such as total cost of ownership  that is composed of both capital expenditure and operational expenditure. The study compares the carbon footprint and power efficiency of Juniper’s routers and those of a leading competitor. The analysis highlights that Juniper routers offer significant advantages over its competition in terms of longevity, cost savings, and environmental impact. The analysis presents detailed TCO models of four different network use cases.
