A.2 Advanced Load Balancing

We will describe Inbound Load Balancing using “Weighted round robin” algorithm for three Internet servers:

1. Web server,

www.example.com,

using WAN1 – WAN2, with ratio of 1:2

FTP server,

ftp.example.com,

using WAN1 –WAN4, with ration of 1:2:3:4

3. Mail server,

mail.example.com

using WAN3 & WAN4, with ratio of 3:4

The ratio of 1:2 means that every return of IP address from WAN1, there will be two returned IP addresses

from WAN2 for the DNS request.

For the Load Balancing “Weighted round robin” algorithm, you should specify the data rate of each individual

WAN ports.

bandwidth. The

bandwidth must be the correct

value provided by ISP, or the

not work properly.

Do the same configuration for

the other WAN ports.
