gbproxy: Redundancy within proxy pair
Added by laforge almost 4 years ago.
Updated almost 3 years ago.
Description
A gbproxy pair features a redundant connection between the BSS and SGSN side.
Should either of the two proxies within a pair be inoperational, the NS-VCs over the E1 circuits on the BSS side of that one proxy are getting BLOCKED and traffic between BSS and SGSN transparently continues to flow via the other proxy of the pair.

Some message sequence charts describing how the state replication, pro-/de-motion should work.
There is also a wiki page describing our approach: Redundancy_between_GbProxy
pushed a patch to support the advertisement of foreing IP endpoints in IP-SNS. It's untested and just in gerrit for soliciting some early review at https://gerrit.osmocom.org/c/libosmocore/+/23521
I'm planning related TTCN3 tests, once I've introduced proper "full mesh NS-VCs on IP-SNS" in TTCN3.
