Hello Johannes,
FYI, there already was a discussion about GSMTAPv3:

but unfortunately, nobody has invested time into this (yet?).
1) Why the design with encapsulating it in UDP?
This gives us a possibility to "demux" multiple GSMTAP streams on the
receiving side, e.g. if you are running multiple processes.
2) The format of gsmtap doesn't seem very
extensible [...]
ACK. I definitely support the idea of using TLVs.
With best regards,
Vadim Yanitskiy.
