TCO Comparison: Private WAN vs. Managed Service
Enterprises typically use MPLS, SD-WAN, or Carrier Ethernet services to connect their locations. These managed network services are ubiquitous and easy to deploy; however, a recent ACG Research report indicates that it sometimes makes economic sense for an enterprise to build a private network with dark fiber.
The ACG Research TCO Comparison Report provides an overview of enterprise private wide-area networks (WANs) and compares the total cost of ownership (TCO) of a private WAN with dark fiber to a managed Carrier Ethernet service. It also identifies the criteria for when enterprises should consider the private WAN option:
- Link speeds greater than 70 Gbps
- Ultra-low-latency requirements
- Requirements for high-availability network topologies
