This setting specifies the LAN servers that handle requests for the
service, and the relative weight values.
The amount of traffic that is distributed to a server is proportional to
the weight value assigned to the server relative to the total weight.
Example:
With the following weight settings on a PePLink Balance:
demo_server_1: 10
demo_server_2: 5
The total weight is 15 = (10 + 5)
Matching traffic distributed to demo_server_1:
67% = (10 / 15) x 100%
Matching traffic distributed to demo_server_2:
33% = (5 / 15) x 100%
