I recently upgraded my network from 1Gbp to 10Gbps. With the 1Gbp network, I had a transfer speed on LAN of about 100-120MB/s.

My network has: 1 pyhsical router bridged. 2 physical wired NICs for WAN and LAN. 1 host machine Debian based OS, running hypervisor/VMM KVM/Qemu/Virt manager. 1 VM router OPNsense (FreeBSD based).

In SDNs I use mininet and create different topologies such as a tree, fat tree, linear, and others, connecting them with the Ryu controller to monitor flows. The switch I used is OVSK and the links are TC link with bw=0.01MBps, delay=1s, loss=50-90%, queue size=5-100packets, and use_htp=True. Also, change the used queue and Qos by "ovs-vsctl -- set Port s1-eth1 qos=@newqos .....". But when returning to the monitored flow I found that collision and Tx/Rx drop/error were always zero and did not change. The traffic generates using continuous ping, Iperf3, and python server and clients script.
