Many complex networks in the real world have community structures -- groups of well-connected nodes with important functional roles.

In this work, we propose to use `Ricci flow metric', to define the distance between two nodes in a network.

Analysis of Internet topologies has shown that the Internet topology has negative curvature, measured by Gromov's "thin triangle condition", which is tightly related to core congestion and route reliability.
