Feature: Configurable retry timings for SMF / UPF heartbeats
mgumz opened this issue · comments
Between SMF and UPF continuous heartbeat requests are sent to detect availability of the associated UPFs. If these heartbeat requests are not replied in a given time frame, the UPF is considered to be unavailable and thus all the sessions are released.
The timeout value at the moment is hardcoded and rather strict:
Lines 643 to 647 in 09e97cb
5s for the first timeout
0.5 time out for retries
5 retries
Which makes it like 7.5s to deduce the UPF is not reachable.
For some deployment scenarios that is a really tight deadline to meet.
With a configurable values the situation could be adjusted to the concrete deployment scenario.
Closed. Implemented in release 2.8.3.
