The NSF International Research Network Connections Program (IRNC) funds five projects to provide network connections linking U.S. research networks with peer networks throughout the world. Links funded by this program support science and engineering research and education applications. The visualization below depicts the layer two links between the IRNC funded routers at city granularity.

You can select the router nodes or the links to display additional information. You can use the drop-down menu icon ( ) in the upper-right hand side of the display to include or exclude the links by project.
