I can’t provide the full answer, only the starting point.
SQL*Net is sitting on top of TNS (Transparent Network Substrate) and is how your connection is established and then used to send commands and results between the client and server. You will need to dig into the SQL*Net architectural documentation to try find an answer. It is unlikely to be a ‘simple’ format, and I would expect it to be propriatary and subject to additional licenses to get to the underlying specifications.
