LTE bandwidth #124

Open daviddvs opened 6 years ago

daviddvs commented 6 years ago

My startup configuration is based on the lte example script. I have modified TDF parameter in order to be close to a real time simulation. After some TCP and UDP tests with iperf tool, I get upside/downside bandwidth value of around 2 Mbps for a connection between an UE and a wired host (connected to the S-GW through another Mininet OVS switch). OpenNet is running in an Ubuntu 14 VM on VirtualBox.

Are these measuements correct? Is there any parameter I could configure to improve those results?

This limitation is due to RB (resource block) implementation in NS-3 LENA (LTE) module. Please visit ns-3-users or check NS-3 LENA documents for further detail about RB implementation. Sorry for that we are not capable to give further comment for NS-3 LENA implementation issue.
