UE Network slicing Test

[emKiran]

Hi @aligungr ,
Im using Open5gs and UERANSIM for the 5G setup in my lab. Now I have scenario, I'm using 2 UEs with Network slice(SST) 1 and 2. According to the 3GPP specification SST: 1 is for EMBB and SST: 2 is for URLLC. I have deployed UEs in the VM. The gNodeB and UPF are deployed in the baremetal. The open5gs core network is on another system under the same network.
The 2 UEs gets attached to the network successfully and I will get IP for both the UEs which implies PDU session for both the UEs are successfull.
Now I'm trying to test both the UEs
The first UE has IMSI-001010000000070, dnn: embb ,SST: 1, UL- 1Gbps and DL -1Gbps, IP: 10.45.0.8
The second UE has IMSI-001010000000071, dnn:urllc, SST: 2, UL- 10Mbps and DL- 10Mbps , IP:10.46.0.6
According to the 3GPP specification the UE with SST: 2 must have very low latency compared to the UE with SST: 1
I have performed the test using Iperf3 tool for bandwidth and I have got the results of the bandwidth as expected
I have performed the ping test from each UE to the google.com and i cannot see any latency difference
Also I have tested send the file of 90Mb to the different system through each UE but i can see the UE with SST: 1 is much speeder than UE with SST: 2

My question is can we really achieve the low latency using gNodeB simulators if yes, does the UERANSIM support that?
If we cannot use simulators for slice testing do we need any gNodeB hardware?

Thanks & Regards,
