test D46046 for cc_cubic
loss resilience test
One data sender and one data receiver in LAN. Both are Virtual Machines (VMs). Each VM is hosted by Bhyve in a separate physical box (Beelink SER5 AMD Mini PC) that is using FreeBSD 14.1 release OS. The physical boxes (Beelink SER5 AMD Mini PCs) are connected through a 1Gbps Ethernet hub, which is connected to a 1Gbps router.
test config
Test TCP congestion control performance of cubic & newreno in VM environment with 1%, 2%, 3% or 4% incoming packet drop rate at the Linux receiver.

TCP friendly test
I design this test based on the TCP-friendly fairness ratio (Jain's fairness index) referenced in my publication "Exploring parallelism and desynchronization of TCP over high speed networks with tiny buffers".
Two data senders and one data receiver in LAN. Senders are Virtual Machines (VMs). The Linux receiver is a physical box(Beelink SER5 AMD Mini PC). Each VM is hosted by Bhyve in a separate physical box (Beelink SER5 AMD Mini PC) that is using FreeBSD 14.1 release OS. All physical boxes (Beelink SER5 AMD Mini PCs) are connected through a 1Gbps Ethernet hub, which is connected to a 1Gbps router.
test config
Test TCP friendly ratio of (Jain's fairness index) cubic vs. newreno in VM environment with congestion (packet drops) on the way to the Linux receiver.
