Abstract: Techniques and architecture are disclosed for inferring a unified topological model of a hidden topology comprising dispersing data packets from a source to at least one receiver, and collecting individual end-to-end packet statistics; collecting aggregate end-to-end statistical measurements between a plurality of enclaves situated at an edge of an unknown network; identifying shared path correlations relating to shared links traversed between at least one root enclave and one or more leaf enclaves; constructing topological metrics as a directed tree corresponding to shared path correlations; inferring a unified topological model and routing paths of the unknown network based on the plurality of topological metrics collected by the plurality of enclaves; validating consistency between the subsequent end-to-end statistical measurements and the unified topological model of the hidden topology; and updating the inferred unified topological model of the hidden topology in accordance with observed inconsistencies.
