Good Day every one! =0A=0AWe have a situation and we are looking for a solu=
tion (the=0Aclient is specific to implement this way):=0A=0AWe are using Fr=
eeBSD FW cluster (2 units) for our DMZ zone.=0AWe are using CARP for VIP an=
d round robin load balance. The=0Aresult is not always balance, most of the=
 times it is 80/20.=0AWe are looking at the following solution:=0AImplement=
 a solution that provides LB based on the=0Afollowing factors:=0A=0A1.=C2=
=A0=C2=A0=C2=A0 CPU=0A2.=C2=A0=C2=A0=C2=A0 Memory=0A3.=C2=A0=C2=A0=C2=A0 Et=
hernet traffic utilization=0A=0ATheoretically I can think when a packet com=
es to FW1, if it is busy (say CPU is 80%) then we need to implement a solut=
ion to send the packet to FW2 and vice verse. =0AI heard that some tools ex=
ist to complement CARP for this purpose, but could not find at Google. =0A=
=0AI would highly appreciate any suggestions on this (or alternate solution=
s =E2=80=93 we know we can use LB appliances, but we will have to many of t=
hem for several other servers too). =0A=0AI would appreciate your help or a=
ny alternate suggestions on how we can achieve this solution (apart from CA=
RP). =0A=0A=0AHave lots of fun,=0A =0ASincerely, =0A=0A =0AHari=0A=0A=0A=0A=
