test TCP CC in VM over 1Gbps LAN
Contents
Linux VM receiver
One data sender and one data receiver and 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 hub, which is connected to a 1Gbps router.
test config
Test TCP congestion control performance of CUBIC & NewReno in VM environment with 1% incoming packet drop rate at the Linux receiver. Then, also test with 2% drop rate.
