Confirm srsUE and srseNB do not work with DPDK? #1445
-
|
Hey everyone. Just wanted to confirm that only the srsRAN Project gNB works with DPDK, and not the UE or eNB from this repo? I see that the gNB has an option in CMAKE to build for DPDK, but this is not there for the UE or eNB. I am experiencing instability between the UE and eNB when I start sending data via iperf (at pretty high speeds, 20 MHz bandwidth). Additionally I am experiencing instability intermittently when data is flowing. When these errors happen I get Underflow warnings from the UE, and I was hoping that DPDK might help solve the issue. I have already done all the performance tuning I can think of (except DPDK). |

Hi, srsRAN 4G does not support the use of DPDK. For stability issues, consider using the performance script that comes with srsRAN Project. In scenarios where you are transmitting over-the-air, try adjusting the gain values, this may give you a more stable connection between the UE and gNB. You can use the console metrics to inform how these changes are impacting the radio link. It is worth noting that srsUE is not intended to be used in high-throughput or deployment-capable scenarios, and some performance issues should be expected. |
