SCION Path Oracle
SCION Path Oracle is an HTTP service deriving dynamic path metrics in SCION. networks. Applications can donate their experienced performance on a path to the Path Oracle, which derives an internal network view from those donations. Other clients may query the Path Oracle for scores to a given destination AS to perform a more sophisticated path selection.
This service gets implemented in the course of a master thesis at the Otto von Guericke University in Magdeburg.
