The Osmocom Signal Transfer Point is a SS7 Transfer Point implementing MTP routing as well as SIGTRAN SG (Signaling Gateway) functionality.
The program is currently part of the libosmo-sccp git repository, as it is basically just a small main loop + VTY interface wrapped around the libosmo-sigtran code.
SIGTRAN protocol support¶OsmoSTP supports all transport protocols implemented in [[libosmo-sigtran:]]. At time of this writing (October 2017), this includes:
- SCTP + M3UA + SCCP
- SCTP + SUA
- IPA + SCCP (experimental
We're looking for contributions/funding to add more protocols like M2UA, M2PA
traffic mode support¶
OsmoSTP currently only implements override and doesn't implement the load-share or broadcast traffic modes. Contributions in whatever form are welcome.
