FYI: Last night I a) merged the SCTP support for libosmo-netif to master b) moved the sua code from osmo-iuh into the libosmo-sccp repository, where we now build a shared libosmo-sigtran.so, which will be linked by the MSC, SGSN and HNB-GW code for the IuCS/IuPS interface. Unlike the spec demands, we will not use SCCP in M3UA in SCTP here, but will use SUA in SCTP as a simplification. Furthermore, the SUA code in libosmo-sigtran does not yet a) fully implement all the correct state machine transitions and inactivity timers (this is to be done) b) implement the ASP management state machines This is done as a short-cut as we initially only want to communicate between our own network elements. What's important is that we can use wireshark for decoding the protocol stacking that we use, and that the SCCP USER SAP is specified in a way that will enable us to put SCCP+M3UA or other sigtran dialects underneath the RANAP code in the future, as needed.
