Purpose
This test is intended to show uplink traffic flow is with higher priority gbr bearer configured in microslice.
Test infrastructure
Celona network w/ (1) AP
1 UE under test
Iperf3 server
UE on QCI 3
SIM of the device is mapped to device group where an application (QCI3) - the application here has a server IP as filter i.e. all traffic to < server IP> will be mapped to QCI3 on the UE
Configured ports in CSO UI mapped to device group.
Test characteristics
This test involves the following parameters and/ or variables (in addition to those described in the General Test Details and Characteristics article and steps to configure MicroSlices in Celona Orchestrator -
Recorded Data
In addition to the information described in the General Test Details and Characteristics section and the test characteristics described, the following information is recorded:
Observe the traffic flow is mapped to the configured GBR bearer
UE throughput should be preserved
Procedure
Start UL UDP traffic on UE using iperf3
Please note the UE and the iperf servers must be in sync at least to ensure these values are accurate
Command on UE
Iperf3 -c <client ip> -b 2M -u -t 999 -l1300 -I 1 -p <port> -e
Command on Server
Iperf3 -s -i 1 -u -e -p <port>
Observe the traffic flow is mapped with the GBR bearer configured
Start TCP dump or pcap file capture at eNodeB/gNodeB
