Good Day every one! =0A=0AWe have a situation and we are looking for a solu=
tion (the client is specific to implement this way):=0A=0AWe are using Free=
BSD FW cluster (2 units) for our DMZ zone. We are using CARP for VIP and ro=
und robin load balance. The result is not always balance, most of the times=
 it is 80/20. =0AWe are looking at the following solution:=0A=0AImplement a=
 solution that provides LB based on the following factors:=0A=0A1.=09CPU=0A=
2.=09Memory=0A3.=09Ethernet traffic utilization=0A=0ATheoretically I can th=
ink when a packet comes to FW1, if it is busy (say CPU is 80%) then we need=
 to implement a solution to send the packet to FW2 and vice verse. =0A=0AI =
heard that some tools exist to complement CARP for this purpose, but could =
not find at Google. =0A=0AI would highly appreciate any suggestions on this=
 (or alternate solutions =E2=80=93 we know we can use LB appliances, but we=
 will have to many of them for several other servers too). =0A=0AHave lots =
of fun,=0A=0ASincerely, =0A=0AHari=0A=0A=0A      Add more friends to your m=
essenger and enjoy! Go to
