Description:
With NAT enabled, UDP/TCP Scaled Traffic Streams/Flows say ~4 Million Scenario with 24K Subscribers.
All the Traffic flows are not getting resolved completely
To Reproduce
Steps:
We are trying to bring up 24K Subscribers with 180 Flows(traffic streams snippet json is below)
Wait for all 24K subscribers to get established.
Look for all the scaled traffic (say around 3Million) flows are getting resolved
Even after 10mins of waiting, didnot see all traffic flows got resolved.
Version (bngblaster -v):
root@SN-STD-25-421167005:/home/supervisor # bngblaster -v
Version: 0.8.34
Compiler: GNU (9.4.0)
IO Modes: packet_mmap_raw (default), packet_mmap, raw
root@SN-STD-25-421167005:/home/supervisor #
Steps to reproduce the behavior:
1. ...
**Expected behavior**
All Traffic flows are to be resolved in scaled case, as we should not see any limitation here.
**Screenshots**
Blaster Snapshot showing all traffic streams not resolved
**Additional context**
