Given some of the data we already had on hand, we instead
broke out market sizes by product segment and geography.
This allowed us to understand not just the global opportunity
in enterprise telecom, but also:
- limit the analysis to larger enterprises with a clear definition of employee counts and revenue;
- focus directly on the components of the WAN (not ancillary enterprise services such as mobile plans and IT outsourcing); and
- track how individual products and services like MPLS IPVPN and DIA contribute to the total market size.
This product explores:
- The total range of global WAN revenues across hundreds of runs of our model
- The contribution of each product to the total WAN market size including:
- MPLS port revenue
- DIA port revenue
- Local access revenue
- Business broadband revenue
- SD-WAN revenue
- Separate WAN market revenue data for nine geographic regions
- Results broken out both by product revenue and geographic region
