Symptoms

ACTUAL BEHAVIOR  
---------------
In an Active-Active Elastic Charging Engine (ECE) setup, it is observed that there is a network issue between Diameter Gateway (DGW|dgw) Site1 and HTTP Gateway (HTTP GW) Site2 and same with dgw site2 to http site1.

As per the setup, SITE2 customers rating request passed to SITE1 DWG should be routed to SITE2 HTTP GW for rating in SITE 2. Similarly SITE1 customers rating request passed to SITE2 DWG should be routed to SITE1 HTTP GW for rating in SITE1 ECE.

While doing the performance testing via Seagull, online rating request are timed out as request is not reaching/delayed request ece-http load balancer on site2.
Both these scenarios are not working in Cloud Native Setup, seeing DIAMETER_TOO_BUSY (3004) and timeout error.
It is observed that there is a network latency issue between dgw site1 and ece-http site2 and same with dgw site2 to ece-http site1

EXPECTED BEHAVIOR
-----------------------
Usage rating should go fine.
