PyTNT is a python based tool built off of Scamper to detect MPLS tunnels on Internet paths. PyTNT uses the same MPLS discovery techniques as TNT, but includes more recent features for integration with large topology measurement platgorms.
PyTNT is the result of a replication paper presented at IMC 2025.
PyTNT was developed and tested with Python 3.10.12, but should be compatible with any python version that can run the scamper API. The only package outside of the python standard library is Scamper.
