I find a custom-made  openwrt  firmware can show per ip realtime speed rate , its core was  'cat /proc/net/tiger_ip_stat'.

root@Openwrt:~# cat /proc/net/tiger_ip_stat
IP=192.168.3.1   session_quota=0  upload_quota=0  download_quota=0  session=0 traffic=26535252  upload=4950  download=0
IP=192.168.3.109   session_quota=0  upload_quota=0  download_quota=0  session=0 traffic=746  upload=1240  download=14930
IP=192.168.3.112   session_quota=0  upload_quota=0  download_quota=0  session=0 traffic=746  upload=0  download=0
IP=192.168.3.115   session_quota=0  upload_quota=0  download_quota=0  session=0 traffic=1101  upload=0  download=0

I try to find but only found  a project has slight relation
