About the Interconnection Measurement Project

Participating Internet Service Providers have installed a common tool to measure traffic at their interconnects, the points where ISPs exchange traffic with the greater Internet. This effort includes multiple ISPs, providing direct information on the capacity and utilization of interconnect links. All data and visualizations are of ingress capacity and utilization.

Across the 1,200+ links included in the data set, which represent the diverse and broadly substitutable routes available for Internet traffic flows, the Project reveals that capacity is roughly 50% utilized during peak periods, and that capacity continues to grow to address continued traffic growth. Further segmentation and analysis of the data is available, which will be regularly refreshed to provide a dynamic picture of how the Internet is evolving.

CITP and the participating ISPs will annually assess whether the project remains relevant as Internet interconnection continues to evolve.

The Interconnection Measurement Project

1Q2017 Update – Today, CITP updated the Interconnection Measurement Project website with the monthly data for January 2017 through March 2017.  The site now includes eighteen months of data, starting in October 2015.  Throughout the year and a half of data, aggregate peak utilization has remained below 50 percent, except in one instance where the monthly aggregate peak utilization reached just 51 percent (January 2016).  Over the eighteen-month period, aggregate interconnection capacity has grown by 74 percent, while aggregate peak usage has grown by only 58 percent.
