The union of all shortest path trees GUspt is the maximally observable part of a network when traffic follows shortest paths. Overlay networks such as peer to peer networks or virtual private networks can be regarded as a subgraph of GUspt. We investigate properties of GUspt in different underlying topologies with regular i.i.d. link weights. In particular, we show that the overlay GUspt in an Erdös-Rényi random graph Gp (N) is a connected GPc (N) where Pc ∼ log N/N is the critical link density, an observation with potential for ad-hoc networks. Shortest paths and, thus also the overlay GUspt, can be controlled by link weights. By tuning the power exponent α of polynomial link weights in different underlying graphs, the phase transitions in the structure of GUspt are shown by simulations to follow a same universal curve FT (α) = Pr[GUspt is a tree]. The existence of a controllable phase transition in networks may allow network operators to steer and balance flows in their network. The structure of GUspt in terms of the extreme value index α is further examined together with its spectrum, the eigenvalues of the corresponding adjacency matrix of GUspt.
