Daniel Willmann 37518b3409 Don't route messages to an SGSN if it is down 
If an SGSN in a pool is down we expect the messages to instead be sent
to a different SGSN in the pool. That SGSN will not necessarily know
what to do with those messages, but it should (implicitly) detach that
UE so that it can reattach at the new SGSN. Otherwise UEs on a failed
SGSN would simply stop working as the messages would never be forwarded
anywhere.

About osmo-gbproxy

osmo-gbproxy is a proxy for the Gb interface within the 3GPP GERAN (GPRS/EDGE RAN) architecture. It is part of the Osmocom Open Source Mobile Communications projects.

It allows you to aggregate many Gb links/connections into one. It also has the ability to convert between different Gb interface protocol stacking, such as from Gb-over-FrameRelay to Gb-over-IP.

Until 2021 it used to be part of the osmo-sgsn git repository, and before that (until 2017) part of openbsc.git
