DSR Multihoming SCTP Association Terminates Unexpectedly (Doc ID 2288315.1)

Last updated on MAY 25, 2023

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 7.0.1 and later


A multihoming SCTP association is established between DSR and HSS. 

The HSS sends a cross-path HEARTBEAT packet.

This packet is mistakenly balanced by IPFE to the MP2. 

MP2 responds with SCTP ABORT.

HSS considers SCTP association terminated and responds with an ABORT on subsequent DSR messages.
