[XL] Change in libosmo-sigtran[master]: Add TCAP based loadsharing/routing
by daniel 28 Nov '25

28 Nov '25

Attention is currently required from: laforge, lynxis lazus, pespin. daniel has uploaded a new patch set (#16) to the change originally created by lynxis lazus. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/41309?usp=email ) The following approvals got outdated and were removed: Code-Review+1 by pespin, Verified-1 by Jenkins Builder Change subject: Add TCAP based loadsharing/routing ...................................................................... Add TCAP based loadsharing/routing TCAP based loadsharing will share the load based on the TCAP oTID and dTID. Because TCAP are session based, a TCAP session based tracking is implemented, to allow following traffic to forwarded to the same ASP. This TCAP session tracking is similar to IP connection tracking. ASPs within an AS can use the new IPA TCAP ROUTING protocol to register for specific TCAP ranges. TCAP sessions initiated by a peer (traffic towards such loadsharing AS/ASP), will use the oTID of the `TCAP Begin` to loadshare and select a ASP. Further if the TCAP session was initiated by a `loadshared` ASP, the oTID will be added to the session tracking.
