[USRP-users] Suggested SFP+ for Ettus N310

2022-07-27 Thread Federico Civerchia
Dear Community, I have recently bought two new Ettus N310 and I have started to verify the connection with the hosts. The NIC interfaces mounted in the hosts are Intel X520-DA2 and Broadcom BCM57414 NetXtreme-E 10Gb/25Gb. Unfortunately, the benchmark for both USRP fails or I have errors like

Hi Rob, Marcus, thank you for your answers. Yes, I have packet loss with ping and also with iperf3 (considering udp) at low rates (500Mb, 1Gb). From the host side I can also see continuous disconnection and re-connection of the link. For the Intel X520-DA2 NIC, I have bought Intel SFP+ (E10GS

Yes, the issue was related to the optical cables in single mode. Using MMF cables resolved the problem. Thank you for your support. Federico On 28/07/22 21:22, Marcus D. Leech wrote: On 2022-07-27 11:06, Federico Civerchia wrote: Dear Community, I have recently bought two new Ettus N310

[USRP-users] Late packets performance Issues on N310

2022-10-12 Thread Federico Civerchia
Hi community, I am using openairinterface to perform some tests with 5G SA. During the test phase, I can see a lot of "LLL" (most of the time hundreds, sometime thousands of these) from time to time. These late packets do not represent an issue with lower throughput, but if I try to send

[USRP-users] Info about processor frequency

Dear community, I am working with a N310 in a 2x2 MIMO setup. What I noticed is that if I consider a processor with a base frequency lower than 3.5GHz, I have several real-time problems with many late packets (s). However, if I consider processor with 3.5GHz or higher base frequency, this
